Abstract
Introduction: The lipid lowering class of drugs known as "Statins" are
being increasing recognized for their pleiotropic effects which include
anti-inflammation, antioxidant, vasodilatation, improved endothelial
function and stabilization of atherosclerotic plaques. These effects may
counteract, to some extent, the deleterious impact of surgical stress on
various organ systems during the perioperative period. Areas covered: A
literature review was undertaken to examine current evidence for the
effect of perioperative statin use on postoperative morbidity and
mortality. A search of PubMed, Medline and Scopus databases was performed
using a combination of search terms including statins and perioperative
risk reduction, outcomes, morbidity and mortality. Further searches were
made on specific areas such as statins and thrombosis, kidney injury,
renal protection, cancer, cost and safety. Expert opinion: Current
evidence supports a reduction in cardiovascular morbidity and mortality
associated with perioperative statin use in high risk patients undergoing
non cardiac surgery and this represents a very cost effective application
of statin therapy with few adverse events reported. Data is emerging that
point to other benefits such as renal protection but this requires further
confirmation from prospective studies. Future research needs to address
the questions of the optimal type, timing and dosage of statin therapy as
well as whether there are problems associated with abrupt withdrawal and
adverse effects associated with long term use. Informa UK, Ltd.

Abstract
CONTEXT The Airtraq is a disposable optical laryngoscope that is available
in a double-lumen tube version. Inserting a double-lumen tube is generally
more difficult compared to conventional endotracheal intubation, mainly
due to its configuration. OBJECTIVE The aim of this study was to compare
the Airtraq with the Macintosh laryngoscope for intubation with a
double-lumen tube in patients undergoing elective thoracic surgery. The
main outcome was time needed for successful intubation. DESIGN
Prospective, randomised clinical trial. SETTING A single centre,
University Hospital of Wu rzburg, Germany, between July 2009 and June
2011. PATIENTS After a scout laryngoscopy with a Macintosh laryngoscope,
60 adult patients were intubated by an anaesthesiologist with either an
Airtraq (n=30) or a Macintosh laryngoscope (n=30). MAIN OUTCOME MEASURES
The time needed for correct intubation, checked by flexible bronchoscopy,
was recorded. The intubation difficulty scale (IDS) and Cormack and Lehane
grade were noted. Haemodynamic variables and any evidence of oropharyngeal
trauma were documented as well as postoperative sore throat, hoarseness
and dysphagia. RESULTS The mean time needed for correct intubation was
20.1+/-16.5 s in the Airtraq group and 17.5+/-10 s in the Macintosh group
(P=0.86). All intubations in both groups had an IDS less than 4. The
Cormack and Lehane grade was I in all 30 patients in the Airtraq group; in
the Macintosh group, it was I and II in 17 and 13 patients, respectively.
The incidence of hoarseness was significantly higher in the Airtraq group
24 h postoperatively (P=0.01). CONCLUSION There was no significant
difference between the Airtraq and the Macintosh laryngoscopes regarding
the time needed to insert a double-lumen tube during elective thoracic
surgery. Only subtle enhancement of visualisation and a higher incidence
of hoarseness were observed in the Airtraq group. The Airtraq device did
not result in superior patient safety in this setting. 2013 Copyright

Abstract
Background-Vorapaxar is a novel antagonist of protease-activated
receptor-1, the primary receptor for thrombin on human platelets that is
also present on vascular endothelium and smooth muscle. Patients with
peripheral artery disease are at risk of systemic atherothrombotic events,
as well as acute and chronic limb ischemia and the need for peripheral
revascularization. Methods and Results-The Trial to Assess the Effects of
SCH 530348 in Preventing Heart Attack and Stroke in Patients With
Atherosclerosis (TRA2degreeP-TIMI 50) was a randomized, double-blind,
placebo-controlled trial of vorapaxar in 26 449 patients with stable
atherosclerotic vascular disease (myocardial infarction, stroke, or
peripheral artery disease). Patients with qualifying peripheral artery
disease (n=3787) had a history of claudication and an ankle-brachial index
of <0.85 or prior revascularization for limb ischemia. The primary
efficacy end point was cardiovascular death, myocardial infarction, or
stroke, and the principal safety end point was Global Utilization of
Streptokinase and t-PA for Occluded Coronary Arteries (GUSTO) bleeding. In
the peripheral artery disease cohort, the primary end point did not differ
significantly with vorapaxar (11.3% versus 11.9%; hazard ratio, 0.94; 95%
confidence interval, 0.78-1.14; P=0.53). However, rates of hospitalization
for acute limb ischemia (2.3% versus 3.9%; hazard ratio, 0.58; 95%
confidence interval, 0.39-0.86; P=0.006) and peripheral artery
revascularization (18.4% versus 22.2%; hazard ratio, 0.84; 95% confidence
interval, 0.73- 0.97; P=0.017) were significantly lower in patients
randomized to vorapaxar. Bleeding occurred more frequently with vorapaxar
compared with placebo (7.4% versus 4.5%; hazard ratio, 1.62; 95%
confidence interval, 1.21-2.18; P=0.001). Conclusions-Vorapaxar did not
reduce the risk of cardiovascular death, myocardial infarction, or stroke
in patients with peripheral artery disease; however, vorapaxar
significantly reduced acute limb ischemia and peripheral
revascularization. The beneficial effects of protease-activated receptor-1
antagonism on limb vascular events were accompanied by an increased risk
of bleeding. Clinical Trial Registration-URL:

Abstract
Background: The intensity of antiplatelet therapy during percutaneous
coronary intervention (PCI) is an important determinant of PCI-related
ischemic complications. Cangrelor is a potent intravenous adenosine
diphosphate (ADP)-receptor antagonist that acts rapidly and has quickly
reversible effects. Methods: In a double-blind, placebo-controlled trial,
we randomly assigned 11,145 patients who were undergoing either urgent or
elective PCI and were receiving guidelinerecommended therapy to receive a
bolus and infusion of cangrelor or to receive a loading dose of 600 mg or
300 mg of clopidogrel. The primary efficacy end point was a composite of
death, myocardial infarction, ischemia-driven revascularization, or stent
thrombosis at 48 hours after randomization; the key secondary end point
was stent thrombosis at 48 hours. The primary safety end point was severe
bleeding at 48 hours. Results: The rate of the primary efficacy end point
was 4.7% in the cangrelor group and 5.9% in the clopidogrel group
(adjusted odds ratio with cangrelor, 0.78; 95% confidence interval [CI],
0.66 to 0.93; P = 0.005). The rate of the primary safety end point was
0.16% in the cangrelor group and 0.11% in the clopidogrel group (odds
ratio, 1.50; 95% CI, 0.53 to 4.22; P = 0.44). Stent thrombosis developed
in 0.8% of the patients in the cangrelor group and in 1.4% in the
clopidogrel group (odds ratio, 0.62; 95% CI, 0.43 to 0.90; P = 0.01). The
rates of adverse events related to the study treatment were low in both
groups, though transient dyspnea occurred significantly more frequently
with cangrelor than with clopidogrel (1.2% vs. 0.3%). The benefit from
cangrelor with respect to the primary end point was consistent across
multiple prespecified subgroups. Conclusions: Cangrelor significantly
reduced the rate of ischemic events, including stent thrombosis, during
PCI, with no significant increase in severe bleeding. (Funded by the

Abstract
Background: UCP2 (uncoupling protein 2) plays an important role in
cardiovascular diseases and recent studies have suggested that the A55V
polymorphism can cause UCP2 dysfunction. The main aim was to investigate
the association of A55V polymorphism with cardiovascular events in a group
of 611 patients enrolled in the Medical, Angioplasty or Surgery Study II
(MASS II), a randomized trial comparing treatments for patients with
coronary artery disease and preserved left ventricular function.Methods:
The participants of the MASS II were genotyped for the A55V polymorphism
using allele-specific PCR assay. Survival curves were calculated with the
Kaplan-Meier method and evaluated with the log-rank statistic. The
relationship between baseline variables and the composite end-point of
cardiac death, acute myocardial infarction (AMI), refractory angina
requiring revascularization and cerebrovascular accident were assessed
using a Cox proportional hazards survival model.Results: There were no
significant differences for baseline variables according genotypes. After
2 years of follow-up, dysglycemic patients harboring the VV genotype had
higher occurrence of AMI (p=0.026), Death+AMI (p=0.033), new
revascularization intervention (p=0.009) and combined events (p=0.037) as
compared with patients carrying other genotypes. This association was not
evident in normoglycemic patients.Conclusions: These findings support the
hypothesis that A55V polymorphism is associated with UCP2 functional
alterations that increase the risk of cardiovascular events in patients
with previous coronary artery disease and dysglycemia. 2013 Gioli-Pereira

Abstract
Purpose: In this prospective study, the effects of fresh frozen plasma
(FFP) included in pump priming for congenital heart surgery in infants and
children on post-bypass coagulation profiles were evaluated. Materials and
Methods: Either 20% albumin (50-100 mL) or FFP (1-2 units) was added to
pump priming for patients randomly allocated into control or treatment
groups, respectively. Hematologic assays, including functional fibrinogen
level, and rotational thromboelastometry (ROTEM) were measured before skin
incision (baseline), after weaning from car-diopulmonary bypass (CPB) and
heparin reversal, and at 24 hours (h) in the intensive care unit (ICU).
Results: All the baseline measurements were comparable between the control
and treatment groups of infants and children. After heparin reversal,
however, significantly higher fibrinogen levels and less reduced ROTEM
parameters, which reflect clot formation and firmness, were demonstrated
in the treatment groups of infants and children. At 24 h in the ICU,
hematologic assays and ROTEM measurements were comparable between the
control and treatment groups of infants and children. Transfusion
requirements, excluding FFP in pump prime, and postoperative bleeding were
comparable between the control and treatment groups of infants and
children. Conclusion: Although clinical benefits were not clearly found,
the inclusion of FFP in pump priming for congenital heart surgery in
infants and children was shown to improve the hemodilution-related
hemo-static dysfunction immediately after weaning from CPB and heparin
reversal. Yonsei University College of Medicine 2013.

Abstract
Background In this study, cardiac surgery with minimally invasive reversed
C sternotomy was compared with conventional sternotomy in patients
undergoing valve replacement or septal defect repair. Methods In this
prospective randomized study, 35 patients were assigned into one of two
groups for elective cardiac surgery under general anesthesia: Group A
(reversed C sternotomy group) and Group B (conventional sternotomy group).
Intraoperative variables, intubation time, postoperative drainage volume,
pulmonary function tests, sleep quality and quality of life, and
requirement for blood transfusion were compared. Results A significant
difference between the two groups was found in blood transfusion
requirement, extubation time, and drainage volume. Forced expiratory
volume in one second and functional vital capacity were significantly
lower in Group B than in Group A at postoperative Month 1. Total sleep
component score of Pittsburg Sleep Quality Index in Group B patients was
significantly worse at postoperative Month 1. Postoperative assessment of
quality of life (physical and mental) also showed a significant difference
between the two groups. Conclusion These preliminary findings suggest that
creating an access point without compromising the integrity of the sternum
seems to be an advantageous and appropriate technique for suitable
patients undergoing cardiac surgery. 2013 Georg Thieme Verlag KG

Abstract
We aimed to determine the optimal adjunctive anticoagulation regimen for
percutaneous coronary intervention (PCI) in patients presenting with acute
coronary syndrome (ACS) initially treated with fondaparinux. The optimal
adjunctive anticoagulation regimen for PCI in these patients is unclear.
In this open-label, prospective, randomized, multicenter pilot study, we
compared treatment with unfractionated heparin (UFH) versus bivalirudin in
patients with non-ST-segment elevation ACS initially treated with
fondaparinux and undergoing early invasive strategy. The randomized
population consisted of 100 patients (62.7 +/- 12.7 years, 68% men), all
of whom were on clopidogrel. During the angioplasty, patients were
randomized to either bivalirudin or UFH therapy in a 1:1 fashion. Baseline
clinical and angiographic characteristics were similar except for a higher
body mass index in the UFH group (29.4 +/- 4.7 vs. 27.3 +/- 4.2, P =
0.02). Major bleeding was the primary outcome; a major bleeding event was
documented in only 1 patient from the bivalirudin group (2%) and in none
from the UFH group (P = 0.49). There was no death, Q-wave MI, or acute
revascularization in either group. There was no documentation of stent
thrombosis, reinfarction, and catheter thrombus. Data from this
prospective, multicenter pilot study suggest that bivalirudin, compared to
standard-dose UFH, has a similar safety profile in terms of peri-PCI
bleeding and thrombotic events and can be used safely in ACS patients
initially treated with upstream fondaparinux who undergo PCI. (J Interven

Abstract
BACKGROUND: The amount of allogeneic blood transfusion may relate to worse
outcome in cardiac surgery. The reinfusion of red blood cells (RBCs) lost
by patients, including those of chest drains, is a promising strategy to
minimize allogeneic transfusions. STUDY DESIGN AND METHODS: To verify this
hypotheis, 1047 cardiac surgery patients were randomly assigned to either
traditional intraoperative blood salvage followed by chest drain insertion
or intra- and postoperative strategy with the Haemonetics cardioPAT
system. Allogeneic RBC transfusion rate (primary endpoint) and
postoperative complications (secondary endpoint) were recorded at the time
of discharge from the hospital and at first month follow-up visit,
respectively. RESULTS: The cardioPAT arm received 1.20 units of allogeneic
RBCs per patient, whereas the control group required 2.11 units per
patient, and this difference proved to be highly significant (p = 0.02).
We observed a comparable 45-day mortality rate but a lower rate of deep
vein thrombosis (p = 0.04) and atrial fibrillation (p = 0.04) in the
cardioPAT arm. DISCUSSION: A significant reduction in patient exposure to
allogeneic RBCs was observed in the cardioPAT system arm. Complications
were slightly less frequent in the cardioPAT group. The use of the
cardioPAT is a safe and effective strategy to reduce allogeneic RBC
transfusions in cardiac surgery. 2012 American Association of Blood

Abstract
While coronary artery bypass grafting (CABG) has been the standard of care
for patients with unprotected left main coronary artery disease, advances
in percutaneous coronary intervention (PCI) have made stent placement a
reasonable alternative in selected patients. In this review, we address
the results of studies comparing PCI with CABG, discuss the invasive
evaluation of these patients, and the technical approach to percutaneous
revascularization. Furthermore, we discuss future pivotal trials, which
will help define long-term outcomes comparing PCI with surgery.

Abstract
The use of prothrombin complex concentrates (PCCs) and fibrinogen
concentrates (FIBCs) to achieve hemostasis in the perioperative setting as
alternatives to allogeneic blood products remains controversial. To
examine the efficacy and safety of PCCs and FIBCs, we conducted a
systematic review-in accordance with the Preferred Reporting Items for
Systematic Reviews and Meta-Analysis statement-to compare the use of these
transfusion alternatives in bleeding surgical patients. We performed a
literature search of English articles published between July 1997 and July
2012 in MEDLINE via PubMed, The Cochrane Library, and CINAHL. Five
randomized trials and 15 nonrandomized studies with a comparator group
were included in the final review. Studies were sorted into 1 of the
following 3 clinical settings: cardiac surgery, non-cardiac surgery, and
reversal of warfarin anticoagulation. Risk of bias was assessed using the
Cochrane risk of bias tool. With the exception of 2 randomized controlled
trials, the existing body of literature on the use of PCCs and FIBCs in
the perioperative setting was assessed to have a high degree of
methodological bias. Overall, prospective studies in the cardiac surgery
grouping suggested that patients receiving FIBC and/or PCCs required less
allogeneic blood transfusion and had less chest tube drainage. In studies
of warfarin reversal, PCCs more rapidly corrected the International
Normalized Ratio compared to plasma; however, in the setting of
intracranial hemorrhage, functional outcomes were poor regardless of the
reversal strategy. With regards to safety outcomes, reporting was not
uniform and raises concerns of underreporting. Adequately powered,
methodologically sound trials would be required for more definitive
conclusions to be drawn about the efficacy of PCCs and FIBC over
conventional blood components for the treatment of perioperative
coagulopathy in bleeding patients. 2013 Elsevier Inc.

Abstract
Background: Cytomegalovirus (CMV) causes several complications following
cardiac transplantation including cardiac allograft vasculopathy. Previous
studies suggested that immunosuppressive treatment based on everolimus
might reduce CMV infection. Aiming to better characterize the action of
everolimus on CMV and its interplay with patient/recipient serology and
anti-CMV prophylaxis, we analyzed data from 3 large randomized studies
comparing various everolimus regimens with azathioprine (AZA)- and
mycophenolate mofetil (MMF)-based regimens. Methods: CMV data were
analyzed from 1009 patients in 3 trials of de novo cardiac transplant
recipients who were randomized to everolimus 1.5 mg/day, everolimus 3
mg/day, or AZA 1-3 mg/kg/day, plus standard-dose (SD) cyclosporine (CsA;
study B253, n = 634); everolimus 1.5 mg/day plus SD- or reduced-dose
(RD)-CsA (study A2403, n = 199); and everolimus 1.5 mg/day plus RD-CsA or
MMF plus SD-CsA (study A2411, n = 176). Results: In study B253, patients
allocated to everolimus experienced almost a 70% reduction in odds of
experiencing CMV infection compared with AZA (P < 0.001). In study A2403,
CMV infection was low in both everolimus arms, irrespective of CsA dosing,
and in study A2411, patients allocated to everolimus experienced an 80%
reduction in odds of experiencing CMV infection, compared with MMF (P <
0.001). CMV syndrome/disease was rare and less frequent in
everolimus-treated patients. Subgroup analyses showed that the benefit
everolimus provides, in terms of CMV events, is retained in CMV-naive
recipients and is independent of anti-CMV prophylaxis or preemptive
approaches. Conclusions: Everolimus is associated with a lower incidence
of CMV infection compared with AZA and MMF, which combined with its
immunosuppressive efficacy and antiproliferative effects may positively
impact long-term outcomes. 2012 John Wiley & Sons A/S.

Abstract
Objective: To compare the outcome of short-term (<24 hours) versus
longer-term (>24 hours) antibiotic prophylaxis (ABP) in Diabetic patients
undergoing coronary artery bypass graft (CABG) surgery and its impact on
in-hospital incidence of deep Sternal Wound Infection (DSWI) /
Mediastinitis. Patients and method: We performed a cross sectional
comparative study in 160 Diabetic patients undergoing CABG from October
2010 through April 2012. Comparison was made between 80 diabetic patients
receiving less than 24 hours of prophylactic antibiotics with another 80
diabetic patients receiving more than 24 hours of prophylactic antibiotics
undergoing isolated CABG. Surgical Site infection (SSI) was assessed on a
daily basis during the patient's stay in the Department of Cardiac
Surgery, Mayo Hospital/KEMU, Lahore. Diagnosis of identified SSI were
based on fever, pain, redness, secretion, purulent drainage, positive
cultures, clear dehiscence of the sternotomy wound. Results: In-hospital
incidence of Deep Sternal Wound Infection (DSWI)/Mediastinitis was 7.50%
in the group <24h of ABP and 1.25% in the group receiving >24 h of ABP
therapy, and the difference was statistically significant (P=0.042).The
proportion of patients with deep-organ-space involvement (mediastinitis)
and sepsis requiring rewiring were 7 patients (8.75%) for <24 hours and 1
patients (1.25%) in >24 hours of ABP (P=0.030). Similar results were
observed in terms of mortality (8.75% Vs 1.25%). However, the
microorganisms isolated showed a similar distribution in both groups.
Morbidity, infections and the composite outcomes occurred more commonly in
diabetic patients. Conclusions: Diabetes mellitus is an important risk
factor for mortality and morbidity among those undergoing CABG. This study
documents the higher incidence of deep Sternal Wound Infection (DSWI) /
Mediastinitis associated with less than 24h of ABP therapy, suggesting the
need for prolonged ABP in Diabetic patients undergoing CABG.

Abstract
Background: Transvenous lead extraction (TLE) has undergone an explosive
evolution by increasing technology due to incremental problem of lead
infections and malfunctions. We aimed to present our experience in TLE
with Evolution Mechanical Dilator Sheath. Methods: Between June 2009 and
November 2012, Evolution Mechanical Dilator Sheath was used for extraction
of 213 pacemaker (PM) and implantable cardioverter-defibrillator (ICD)
leads in 103 patients in our center. Indications for extraction,
procedural success and complications were defined according to HRS
Guidelines. Results: Indications for TLE were infection in 62 patients
(60.1%), lead malfunction in 40 patients (38.8%) and lead displacement in
1 patient (0.97%). Extracted devices were PM in 40 cases (38.8%), ICD in
42 cases (40.7%) and CRT-D in 21 cases (20.3%). Among 213 leads, 48
(22.5%) were right ventricular, 71 (33.3%) were defibrillator coil, 73
(34.2%) were atrial and 21 (9.8%) were coronary sinus electrodes. Median
time from the preceding procedure was 92 months (18- 264 months). Clinical
success was 99% and complete procedural success with Evolution system
alone was 88.3% (91 patients). Major complications were observed in 1
(0.97%) patients without any mortality. Conclusions: Our experience has
confirmed that the hand powered Evolution system is an effective
extraction tool for chronically implanted pacemaker/ICD leads. Randomized
controlled studies are required to evaluate success and complication rates
in comparison to other techniques. (Figure Presented).

Abstract
Bone marrow derived CD34+ and CD133+ cells, which exhibit endothelial
phenotypes, have been shown to contribute to neovascularization. It has
been shown that selected bone marrow stem cells (BMCs) were more effective
than unselected BMCs in the infarcted myocardium. Therefore we conducted a
systematic review to examine the effectiveness of selected BMCs on
improving LVEF from RCTs to treat CMI. We searched Medline, EMBASE, and
Cochrane database from inception to March 2012. The included studies met
the following criteria: (1) randomized controlled trials (2) CMI patients
who received coronary artery bypass graft (CABG) (3) BMCs were infused
intramuscularly (4) cell injection in periinfarct zone (6) Studies that
had up to 6 month follow-up. The initial search identified 8,433
references, 6 RCTs were met the inclusion criteria. Two of 6 trials
injected selected bone marrow stem cell such as CD34+ and CD133+ and 4 of
6 trials injected unselected BMC to the treatment group. Significant
treatment effect in the studies in which the treatment group injected
CD34+ and CD133+ selected BMC as indicated the LVEF change of 8.61% (95%
CI 6.52 to 10.70) and the studies that infused unselected BMC showed
improvement in LVEF by 4.81% (95% CI, 2.07 to 7.55). The results showed
that selected BMCs were more effective than unselected BMCs. However, the
trials infused selected BMCs tended to use less rigorous study design that
those using unselected BMCs. That is, the trials which were infused
selected stem cell they neither conduct bone marrow aspiration nor sharm
injection in the control group to ascertain blindness. Also they assessed
outcomes with echocardiography instead of MRI that was known to more
precise tool. The intervention effect might be overestimated due to the
study design. Therefore these treatment effects depending on the
difference cell type should be interpreted cautiously.

Abstract
Purpose: Heart transplant recipients who are sensitized pre transplant are
at increased risk for the development of antibody mediated and cellular
rejection post transplantation. The use of induction therapy with
anti-thymocyte globulin (ATG) may reduce the incidence of antibody
mediated rejection (AMR), but this has not been formally studied in a
randomized controlled trial. The purpose of this study was to determine
the impact of ATG induction on the incidence of AMR in a large
single-center experience. Methods and Materials: We identified 170 heart
transplant (HTx) patients transplanted between January 1994 and October
2011, with pre-transplant panel reactive antibodies (PRA) > 10%. Induction
therapy was given based on the treating physician's preference. One-year
outcomes were assessed, including the incidence of treated rejection and
pathology-defined AMR. Results: Of the 170 HTx, 91 received ATG induction
and 79 did not. The mean pre-transplant PRA was significantly higher in
the ATG group (59 +/- 31% vs 43 +/- 32%>,p=0.0015). In the ATG induction
group, there were fewer treated rejection episodes (14% vs 30%,p= 0.01)
and fewer pathology-defined AMR episodes (12% vs 26%, p=0.016). There was
no difference in the incidence of cellular rejection (12% in both groups).
(Table presented) Conclusions: ATG induction therapy for sensitized
patients results in fewer treated rejection epiosdes and a decreased
incidence of pathology-defined AMR. This suggests that ATG induction is
beneficial in sensitized patients, and the results should be confirmed
with a randomized trial.

Abstract
Purpose: Novel therapies are emerging for treatment of AMR, but minimal
data is available comparing efficacy and safety with prevailing
treatments. We tested whether the efficacy of bortezomib (Bzb) in lowering
donor antibody antibodies (DSA) was improved over standard plasmapheresis
(PP)/ IVIG or rituximab therapy for AMR. Methods and Materials: Ten adult
heart transplant recipients with DSA mean fluorescence intensity (MFI)
>1000, biopsy-proven, and/or clinically suspicious AMR were treated for 20
episodes between February 2010 to August 2012. Treatment consisted of PP
(5 days) with IVIG (2 g/kg), rituximab (375 mg/m2), and/or Bzb (0.7-1
mg/m2 x 4) at least 30 days apart. Antibody titers were measured via
single antigen Luminex assay before and after therapy. Parametric and
non-parametric comparisons, linear and logistic regression were used as
appropriate to assess outcomes. Results: There was a greater reduction in
DSA with Bzb therapy (beta-0.58, 95% CI 0.16-0.90, p-0.01) when adjusting
for time to AMR. In those with compromised ejection fraction, there was
improvement after Bzb therapy (p-0.03). Patient survival in both groups
was 100% at 60 days. Conclusions: Compared to PP/IVIG or rituximab, Bzb
was more effective in reducing DSA without a significant effect on the
incidence of infection or survival in this limited data set. There is
indication for a randomized controlled trial comparing Bzb to standard AMR
therapies to help determine clinical and survival benefit. (Table
presented).

Abstract
Purpose: Cardiac allograft vasculopathy (CAV) is a progressive form of
atherosclerosis occurring in heart transplant (HTx) recipients,
contributing to increased morbidity and mortality. High intensity interval
training (HIIT) is effective in patients with coronary artery disease,
resulting in reduced progression of atherosclerosis, but its effect in HTx
has not been investigated. We hypothesized that HIIT also would reduce the
progression of CAV in HTx patients. Methods and Materials: Forty-three
clinically stable HTx recipients > 18 years old, were randomized to either
HIIT or control group (standard care) for one year. Baseline and one year
maximal exercise testing on a treadmill, together with measurement of
inflammatory biomarkers and intravascular ultrasound (IVUS), were
performed. Results: The mean+/-SD age was 51 +/-16 years, 67% were male
and time post HTx was 4.0 +/-2.2 years. VO2peak (mL/kg/min) improvement
was 2.9+/-2.9 in the HIIT group as compared to -0.3+/-2.9 in the control
group (p<0.001), corresponding to 89% and 82% of expected VO2peak level,
respectively. IVUS analysis revealed a mean increase [95% CI] in percent
atheroma volume (PAV) of 0.9 [-0.3, 1.9]% in the HIIT group, as compared
to 2.5 [1.6, 3.5]% in the control group (p=0.021). Similarly, mean
increase [95%CI] in maximal intimal thickness (MIT) was 0.02 [0.01, 0.04]
mm in the HIIT group as compared to 0.05 [0.03, 0.08] mm in the control
group (p=0.054). Qualitative plaque progression (virtual histology
parameters) and inflammatory activity (biomarkers) were similar between
the two groups during the study period. Conclusions: High intensity
interval training among maintenance HTx recipients resulted in a
significantly slower rate of CAV progression as assessed by PAV, and
borderline significant by MIT. Furthermore, improvement in VO2peak was
significantly greater in patients treated with HIIT, suggesting that
routine implementation of exercise protocols could help reduce morbidity
and mortality among HTx recipients.

Abstract
Importance: Infections due to Staphylococcus aureus are serious
complications of cardiothoracic surgery. A novel vaccine candidate (V710)
containing the highly conserved S aureus iron surface determinant B is
immunogenic and generally well tolerated in volunteers. Objective: To
evaluate the efficacy and safety of preoperative vaccination in preventing
serious postoperative S aureus infection in patients undergoing
cardiothoracic surgery. Design, Setting, and Participants: Double-blind,
randomized, event-driven trial conducted between December 2007 and August
2011 among 8031 patients aged 18 years or older who were scheduled for
full median sternotomy within 14 to 60 days of vaccination at 165 sites in
26 countries. Intervention: Participants were randomly assigned to receive
a single 0.5-mL intramuscular injection of either V710 vaccine, 60 mug
(n=4015), or placebo (n=4016). Main Outcome Measures: The primary efficacy
end point was prevention of S aureus bacteremia and/or deep sternal wound
infection (including mediastinitis) through postoperative day 90.
Secondary end points included all S aureus surgical site and invasive
infections through postoperative day 90. Three interim analyses with
futility assessments were planned. Results: The independent data
monitoring committee recommended termination of the study after the second
interim analysis because of safety concerns and low efficacy. At the end
of the study, the V710 vaccine was not significantly more efficacious than
placebo in preventing either the primary end points (22/3528 V710 vaccine
recipients [2.6 per 100 person-years] vs 27/3517 placebo recipients [3.2
per 100 person-years]; relative risk, 0.81; 95% CI, 0.44-1.48; P = .58) or
secondary end points despite eliciting robust antibody responses. Compared
with placebo, the V710 vaccine was associated with more adverse
experiences during the first 14 days after vaccination (1219/3958 vaccine
recipients [30.8%; 95% CI, 29.4%-32.3%] and 866/3967 placebo recipients
[21.8%; 95% CI, 20.6%-23.1%], including 797 [20.1%; 95% CI, 18.9%-21.4%]
and 378 [9.5%; 95% CI, 8.6%-10.5%] with injection site reactions and 66
[1.7%; 95% CI, 1.3%-2.1%] and 51 [1.3%; 95% CI, 1.0%-1.7%] with serious
adverse events, respectively) and a significantly higher rate of
multiorgan failure during the entire study (31 vs 17 events; 0.9 [95% CI,
0.6-1.2] vs 0.5 [95% CI, 0.3-0.8] events per 100 person-years; P = .04).
Although the overall incidence of vaccine-related serious adverse events
(1 in each group) and the all-cause mortality rate (201/3958 vs 177/3967;
5.7 [95% CI, 4.9-6.5] vs 5.0 [95% CI, 4.3-5.7] deaths per 100
person-years; P = .20) were not statistically different between groups,
the mortality rate in patients with staphylococcal infections was
significantly higher among V710 vaccine than placebo recipients (15/73 vs
4/96; 23.0 [95% CI, 12.9-37.9] vs 4.2 [95% CI, 1.2-10.8] per 100
person-years; difference, 18.8 [95% CI, 8.0-34.1] per 100 person-years).
Conclusions and Relevance: Among patients undergoing cardiothoracic
surgery with median sternotomy, the use of a vaccine against S aureus
compared with placebo did not reduce the rate of serious postoperative S
aureus infections and was associated with increased mortality among
patients who developed S aureus infections. These findings do not support
the use of the V710 vaccine for patients undergoing surgical
interventions. Trial Registration: clinicaltrials.gov Identifier:

Abstract
BACKGROUND: The benefits of coronary-artery bypass grafting (CABG) without
cardiopulmonary bypass in the elderly are still undetermined. METHODS: We
randomly assigned patients 75 years of age or older who were scheduled for
elective first-time CABG to undergo the procedure either without
cardiopulmonary bypass (off-pump CABG) or with it (on-pump CABG). The
primary end point was a composite of death, stroke, myocardial infarction,
repeat revascularization, or new renal-replacement therapy at 30 days and
at 12 months after surgery. RESULTS: A total of 2539 patients underwent
randomization. At 30 days after surgery, there was no significant
difference between patients who underwent off-pump surgery and those who
underwent on-pump surgery in terms of the composite outcome (7.8% vs.
8.2%; odds ratio, 0.95; 95% confidence interval [CI], 0.71 to 1.28; P =
0.74) or four of the components (death, stroke, myocardial infarction, or
new renal-replacement therapy). Repeat revascularization occurred more
frequently after off-pump CABG than after on-pump CABG (1.3% vs. 0.4%;
odds ratio, 2.42; 95% CI, 1.03 to 5.72; P = 0.04). At 12 months, there was
no significant between-group difference in the composite end point (13.1%
vs. 14.0%; hazard ratio, 0.93; 95% CI, 0.76 to 1.16; P = 0.48) or in any
of the individual components. Similar results were obtained in a
per-protocol analysis that excluded the 177 patients who crossed over from
the assigned treatment to the other treatment. CONCLUSIONS: In patients 75
years of age or older, there was no significant difference between on-pump
and off-pump CABG with regard to the composite outcome of death, stroke,
myocardial infarction, repeat revascularization, or new renal-replacement
therapy within 30 days and within 12 months after surgery. (Funded by

Abstract
BACKGROUND: Previously, we reported that there was no significant
difference at 30 days in the rate of a primary composite outcome of death,
myocardial infarction, stroke, or new renal failure requiring dialysis
between patients who underwent coronary-artery bypass grafting (CABG)
performed with a beating-heart technique (off-pump) and those who
underwent CABG performed with cardiopulmonary bypass (on-pump). We now
report results on quality of life and cognitive function and on clinical
outcomes at 1 year. METHODS: We enrolled 4752 patients with coronary
artery disease who were scheduled to undergo CABG and randomly assigned
them to undergo the procedure off-pump or on-pump. Patients were enrolled
at 79 centers in 19 countries. We assessed quality of life and cognitive
function at discharge, at 30 days, and at 1 year and clinical outcomes at
1 year. RESULTS: At 1 year, there was no significant difference in the
rate of the primary composite outcome between off-pump and on-pump CABG
(12.1% and 13.3%, respectively; hazard ratio with off-pump CABG, 0.91; 95%
confidence interval [CI], 0.77 to 1.07; P=0.24). The rate of the primary
outcome was also similar in the two groups in the period between 31 days
and 1 year (hazard ratio, 0.79; 95% CI, 0.55 to 1.13; P=0.19). The rate of
repeat coronary revascularization at 1 year was 1.4% in the off-pump group
and 0.8% in the on-pump group (hazard ratio, 1.66; 95% CI, 0.95 to 2.89;
P=0.07). There were no significant differences between the two groups at 1
year in measures of quality of life or neurocognitive function.
CONCLUSIONS: At 1 year after CABG, there was no significant difference
between off-pump and on-pump CABG with respect to the primary composite
outcome, the rate of repeat coronary revascularization, quality of life,
or neurocognitive function. (Funded by the Canadian Institutes of Health

Abstract
Background: Kidney dysfunction is a strong determinant of prognosis in
many settings. Methods: A systematic review and meta-analysis was
undertaken to explore the relationship between estimated glomerular
filtration rate (eGFR) and adverse outcomes after surgery. Cohort studies
reporting the relationship between eGFR and major outcomes, including
all-cause mortality, major adverse cardiovascular events, and acute kidney
injury after cardiac or noncardiac surgery, were included. Results:
Forty-six studies were included, of which 44 focused exclusively on
cardiac and vascular surgery. Within 30 days of surgery, eGFR less than 60
mlmin1.73 m was associated with a threefold increased risk of death
(multivariable adjusted relative risk [RR] 2.98; 95% confidence interval
[CI] 1.95-4.96) and acute kidney injury (adjusted RR 3.13; 95% CI
2.22-4.41). An eGFR less than 60 mlmin1.73 m was associated with an
increased risk of all-cause mortality (adjusted RR 1.61; 95% CI 1.38-1.87)
and major adverse cardiovascular events (adjusted RR 1.49; 95% CI
1.32-1.67) during long-term follow-up. There was a nonlinear association
between eGFR and the risk of early mortality such that, compared with
patients having an eGFR more than 90 mlmin1.73 m the pooled RR for death
at 30 days in those with an eGFR between 30 and 60 mlmin1.73 m was 1.62
(95% CI 1.43-1.80), rising to 2.85 (95% CI 2.49-3.27) in patients with an
eGFR less than 30 mlmin1.73 m and 3.75 (95% CI 3.44-4.08) in those with an
eGFR less than 15 mlmin1.73 m. CONCLUSION:: There is a powerful
relationship between eGFR, and both short-and long-term prognosis after,
predominantly cardiac and vascular, surgery. 2013, the American Society

Abstract
Background: Pediatric cardiac surgery patients are at high risk for
bleeding, and the antifibrinolytic drug tranexamic acid (TA) is often used
to reduce blood loss. However, dosing schemes remain empirical as a
consequence of the absence of pharmacokinetic study in this population.
The authors' objectives were thus to investigate the population
pharmacokinetics of TA in pediatric cardiac surgery patients during
cardiopulmonary bypass (CPB). Methods: Twenty-one patients were randomized
to receive TA either continuously (10 mg/kg followed by an infusion of 1
mgkgh throughout the operation, and 10 mg/kg into the CPB) or
discontinuously (10 mg/kg, then 10 mg/kg into the CPB and 10 mgkgh at the
end of CPB). Serum concentrations were measured at eight time points with
chromatography-mass spectrometry and the data were modeled using Monolix
(Lixoft, Orsay, France). Results: Tranexamic acid pharmacokinetics was
ascribed to a two-compartment open model. The main covariate effects were
body weight and CPB. Representative pharmacokinetic parameters adjusted to
a 70-kg body weight were as follows: systemic clearance, 2.45 l/h; volume
of distribution in the central compartment, 14.1 l; intercompartmental
clearance, 5.74 l/h; and peripheral volume, 32.8 l. In accordance with
this model, the authors proposed a weight-adjusted dosing scheme to
maintain effective TA concentrations in children during surgery,
consisting of one loading dose followed by a continuous infusion.
Conclusions: The authors report for the first time the pharmacokinetics of
TA in children undergoing cardiac surgery with CPB, and propose a dosing
scheme for optimized TA administration in those children. 2013, the

Abstract
The psychological and neurological impact of cardiac surgery has been of
keen empirical interest for more than two decades although reports showing
the prognostic influence of depression on adverse outcomes lag behind the
evidence documented in heart failure, myocardial infarction, and unstable
angina. The paucity of research to date is surprising considering that
some pathophysiological mechanisms through which depression is
hypothesized to affect coronary heart disease (e.g., platelet activation,
the inflammatory system, dysrhythmias) are known to be substantially
influenced by the use of cardiopulmonary bypass. As such, cardiac surgery
may provide a suitable exemplar to better understand the psychiatric
mechanisms of cardiopathogenesis. The extant literature is comprehensively
reviewed with respect to the deleterious impact of depression on cardiac
and neuropsychological morbidity and mortality. Research to date indicates
that depression and major depressive episodes increase major
cardiovascular morbidity risk after cardiac surgery. The association
between depressive disorders and incident delirium is of particular
relevance to cardiac surgery staff. Contemporary treatment intervention
studies are also described along with suggestions for future cardiac
surgery research.

Abstract
The purpose of this study was to analyze the changes over the past two
decades in hospital survival and neurodevelopmental outcomes after
surgical treatment for hypoplastic left heart syndrome. The hypothesis for
this study is that increasing hospital survival following the Stage I
Norwood (S1N) procedure is associated with improvements in
neurodevelopmental outcomes. Studies included in the meta-analysis were
identified by searching Ovid MEDLINE from January 1980 to October 2010. A
total of 72 articles were identified. Fifteen single-center study articles
were appropriate for obtaining survival data and 14 were used for
neurodevelopmental outcomes. Wechsler Intelligence Test IQ scores and the
Bayley II Mental Development (MDI) and Psychomotor Development Indices
(PDI) were the primary neurodevelopmental outcomes included in this
meta-analysis. Metaregression analysis using a mixed-effects model
compared the percent survival and neurodevelopmental scores with the year
of surgery. Hospital survival for the S1N operation increased
significantly from 1996 to 2007 (p < .05). The overall mean survival
during this time period was 80.05% (95% confidence interval [CI],
76.4-84.0%). Standardized Wechsler IQ scores increased significantly from
1989 to 1999 (p < .05) and the mean IQ was 85.09 (95% CI, 82.3-89.5). The
Bayley II MDI increased significantly from 1998 to 2005 (p < .05) with
amean MDI of 86.9 (95% CI, 84.9-88.9). The Bayley II PDI increased
significantly from 1998 to 2005 (p < .05) with a mean PDI of 73.4 (95% CI,
71.2-75.5). Increased survival has been associated with improved but below
normal neurodevelopmental outcomes.

Abstract
BackgroundPerioperative mortality after cardiac surgery has decreased in
recent years although postoperative morbidity is still significant.
Although there is evidence that perioperative goal-directed haemodynamic
therapy (GDT) may reduce surgical mortality and morbidity in non-cardiac
surgical patients, the data are less clear after cardiac surgery. The
objective of this review is to perform a meta-analysis on the effects of
perioperative GDT on mortality, morbidity, and length of hospital stay in
cardiac surgical patients.MethodsWe conducted a systematic review using
Medline, EMBASE, and the Cochrane Controlled Clinical Trials Register.
Additional sources were sought from experts. The inclusion criteria were
randomized controlled trials, mortality reported as an outcome,
pre-emptive haemodynamic intervention, and cardiac surgical population.
Included studies were examined in full and subjected to quantifiable
analysis, subgroup analysis, and sensitivity analysis where possible. Data
synthesis was obtained by using odds ratio (OR) and mean difference (MD)
for continuous data with 95% confidence interval (CI) utilizing a
random-effects model.ResultsFrom 4986 potential studies, 5 met all the
inclusion criteria (699 patients). The quantitative analysis showed that
the use of GDT reduced the postoperative complication rate (OR 0.33, 95%
CI 0.15-0.73; P=0,006) and hospital length of stay (MD -2.44, 95% CI -4.03
to -0.84; P=0,003). There was no significant reduction in
mortality.ConclusionThe use of pre-emptive GDT in cardiac surgery reduces
morbidity and hospital length of stay. 2013 The Author [2013]. Published

Abstract
Objectives: This study compared cross-sectional three-dimensional (3D)
transesophageal echocardiography (TEE) to two-dimensional (2D) TEE as
methods for predicting aortic regurgitation after transcatheter aortic
valve replacement (TAVR). Background: Data have shown that TAVR sizing
using cross-sectional contrast computed tomography (CT) parameters is
superior to 2D-TEE for the prediction of paravalvular aortic regurgitation
(AR). Three-dimensional TEE can offer cross-sectional assessment of the
aortic annulus but its role for TAVR sizing has been poorly elucidated.
Methods: All patients had severe symptomatic aortic stenosis and were
treated with balloon-expandable TAVR in a single center. Patients studied
had both 2D-TEE and 3D imaging (contrast CT and/or 3D-TEE) of the aortic
annulus at baseline. Receiver-operating characteristic curves were
generated for each measurement parameter using post-TAVR paravalvular AR
moderate or greater as the state variable. Results: For the 256 patients
studied, paravalvular AR moderate or greater occurred in 26 of 256 (10.2%)
of patients. Prospectively recorded 2D-TEE measurements had a low
discriminatory value (area under the curve = 0.52, 95% confidence
interval: 0.40 to 0.63, p = 0.75). Average cross-sectional diameter by CT
offered a high degree of discrimination (area under the curve = 0.82, 95%
confidence interval: 0.73 to 0.90, p < 0.0001) and mean cross-sectional
diameter by 3D-TEE was of intermediate value (area under the curve = 0.68,
95% confidence interval: 0.54 to 0.81, p = 0.036). Conclusions:
Cross-sectional 3D echocardiographic sizing of the aortic annulus
dimension offers discrimination of post-TAVR paravalvular AR that is
significantly superior to that of 2D-TEE. Cross-sectional data should be
sought from 3D-TEE if good CT data are unavailable for TAVR sizing. 2013

Abstract
Bradykinin increases during cardiopulmonary bypass (CPB) and stimulates
the release of nitric oxide, inflammatory cytokines, and tissue-type
plasminogen activator (t-PA), acting through its B 2 receptor. This study
tested the hypothesis that endogenous bradykinin contributes to the
fibrinolytic and inflammatory response to CPB and that bradykinin B 2
receptor antagonism reduces fibrinolysis, inflammation, and subsequent
transfusion requirements. Patients (N = 115) were prospectively randomized
to placebo, -aminocaproic acid (EACA), or HOE 140, a bradykinin B 2
receptor antagonist. Bradykinin B 2 receptor antagonism decreased
intraoperative fibrinolytic capacity as much as EACA, but only EACA
decreased D-dimer formation and tended to decrease postoperative bleeding.
Although EACA and HOE 140 decreased fibrinolysis and EACA attenuated blood
loss, these treatments did not reduce the proportion of patients
transfused. These data suggest that endogenous bradykinin contributes to
t-PA generation in patients undergoing CPB, but that additional effects on
plasmin generation contribute to decreased D-dimer concentrations during
EACA treatment.

Abstract
Objectives: To determine the incidence of vitamin D deficiency in neonates
with congenital heart disease and whether differences exist by race. In
addition, we determined the effect of cardiopulmonary bypass on vitamin D
levels and explored associations between 25-hydroxyvitamin D [25(OH)D]
levels and postoperative outcomes. Study design: We performed a secondary
analysis of a prospective randomized controlled trial in 70 neonates
undergoing cardiac surgery. The neonates' 25(OH)D levels were measured in
the operating room before skin incision (baseline), at the cessation of
cardiopulmonary bypass, and at 24 hours postoperatively. Associations
between these levels and clinical outcomes were explored. Vitamin D
deficiency was defined as a 25(OH)D level <20 ng/mL. Results: Vitamin D
deficiency was present in 84% (59/70); concentrations in African Americans
(n = 20) were significantly lower than those of Caucasian/other
race/ethnicity (n = 50) (10.2 +/- 4.2 vs 16.0 +/- 5.6 ng/mL, P < .0001).
The 24-hour postoperative 25(OH)D levels were not different from baseline
and correlated with a reduced postoperative inotropic requirement (r =
-0.316, P = .008). Conclusions: Vitamin D deficiency is prevalent in
neonates with congenital cardiac defects, and lower postoperative 25(OH)D
levels are associated with the need for increased inotropic support in
neonates undergoing cardiac operations. These findings support that
vitamin D deficiency may play a role in myocardial injury and
postoperative recovery and warrants further investigation. 2013 Mosby

What is the survival after surgery for localized malignant pleural
mesothelioma?.

Abstract
A best evidence topic in thoracic surgery was written according to a
structured protocol. This was with the purpose of assisting our management
of patients with localized malignant mesothelioma of the pleura (LMM).
Although the terminology is used inconsistently, this variant has been
formally defined by the WHO as a distinct entity defined as localized
disease histologically identical to the diffuse form but without any
evidence of pleural spread. Treatments for LMM include different
combinations of surgery, chemotherapy and radiotherapy. There is an
impression that LMM may have a better outcome than the commoner diffuse
form of malignant mesothelioma that has been reported to have a survival
between 8 and 14 months. In order to advise our patients on prognosis, we
studied the duration of survival after surgical resection of LMM. A total
of 150 papers were found, of which 16 represented the best evidence to
answer the question. The authors, journal, date, country of publication,
study type, relevant outcomes and results of these papers are tabulated.
It is difficult to combine the results of these 16 papers because both
treatments and results are reported differently. Some report median
survival (range: 11.6-36 months) and others disease-free survival (range:
0 months to 11 years). Median survival to the longest follow-up was 29
months when calculated by pooling data from informative papers using the
Kaplan-Meier method. Our review suggests that survival in LMM is longer
than that generally quoted for the more common diffuse form of malignant
mesothelioma. Hence, aggressive treatment of LMM may be reasonable in
appropriate patients. The Author 2013. Published by Oxford University

Abstract
A best evidence topic in cardiothoracic surgery was written according to a
structured protocol. The question addressed was whether there is any role
for resuscitative emergency department thoracotomy in severe blunt trauma.
Emergency thoracotomy is an accepted intervention for patients with
penetrating cardiothoracic trauma. However, its role in blunt trauma has
been challenged and has been a subject of considerable debate. Altogether,
186 relevant papers were identified, of which 14 represented the best
evidence to answer the question. The author, journal, date, country of
publication and relevant outcomes are tabulated. The 14 studies comprised
2 systematic reviews and 12 retrospective studies. The systematic review
performed by the Trauma Committee of the American College of Surgeons
included 42 studies and a cumulative total of 2193 blunt trauma patients
who underwent an emergency department thoracotomy, reporting a survival
rate of 1.6. According to this review, 15 of the survivors suffered from
neurological sequelae, but survivors from both penetrating and blunt
trauma were included. A systematic review comprising 24 studies reported a
survival rate of 1.4 among 1047 blunt trauma patients. Of the
retrospective studies, 11 report poor survival rates, ranging from 0 to 6.
Only one study reports a higher survival rate (12.2). Five of the studies
reported on the neurological outcome of survivors. The majority of the
studies suffered from limitations due to the small number of included
cases. The reported survival after an emergency department thoracotomy for
blunt trauma is very low in the vast majority of available studies.
Furthermore, the neurological sequelae in the few survivors are frequent
and severe. Interestingly, some author groups recommend that emergency
department thoracotomy should be contraindicated in cases of blunt trauma
with no signs of life at the scene of trauma or on arrival at the
emergency department. Larger, well-designed series will be required to
reach a consensus on valid prognostic factors and specific subgroups of
blunt trauma patients with substantial chances of survival. The Author

Abstract
A best evidence topic in thoracic surgery was written according to a
structured protocol. The question addressed was: in patients with
non-small-cell lung cancer that is found to be unresectable at
thoracotomy, is incomplete resection superior for achieving survival
advantage? Altogether more than 400 papers were found using the reported
search, of which nine represented the best evidence to answer the clinical
question. The authors, journal, date and country of publication, patient
group studied, study type, relevant outcomes and results of these papers
were tabulated. In total, data from an estimated 1083 patients were
analysed. Three-year survival rates varied from 0 to 22 in incomplete
resection and from 0 to 10 in exploratory thoracotomy. Median survival
ranged from 6.5 to 19.1 months in incomplete resection and from 5.3 to 17
months in exploratory thoracotomy. The majority of studies (8/9) found
survival in incomplete resection to be superior. However, only 3/9 studies
presented statistical analysis of results. The largest of these found
superior postoperative survival in incomplete resection (including
residual nodal disease), one study showed a significant survival
difference for R1 but not R2 resection and another with small patient
numbers (n = 29) found no significant difference. We conclude that the
best evidence suggests that there may be a survival advantage from
incomplete resection of non-small-cell lung cancer when there is
microscopic (R1) or nodal residual disease, but not when macroscopic
residual (R2) disease remains. The Author 2013. Published by Oxford

Abstract
Background: Morbidly obese patients have associated diseases, such as
diabetes, hypertension, hyperlipidemia, and cardiovascular disease.
Bariatric surgery improves these obesity-related co-morbidities, including
insulin resistance. Evidence has shown that patients with morbid obesity
have postprandial hypertriglyceridemia (HTG) and that this type of HTG is
related to the degree of insulin resistance. Also, bariatric surgery
produces a dramatic reduction in triglyceride levels. However, it is
unknown whether patients with postprandial HTG have a different clinical
evolution after bariatric surgery. The setting of our study was a
university hospital. Methods: We studied 57 morbidly obese patients who
had mild or severe postprandial HTG after fat overload (<30 mg/dL or >90
mg/dL increase in triglycerides, respectively). All the patients underwent
bariatric surgery. After surgery, the anthropometric and biochemical
variables and the Homeostasis Model Assessment of Insulin Resistance were
measured for 1 year at 0, 15, 30, 45, 90, 180, and 365 days after surgery.
Results: The patients with more severe postprandial HTG had a greater
percentage of change in the Homeostasis Model Assessment of Insulin
Resistance at 30, 90, and 180 days after surgery than the patients with
less severe postprandial HTG. Multiple regression analysis showed that the
postprandial triglyceride levels predict the variation in the Homeostasis
Model Assessment of Insulin Resistance index, more so than did traditional
variables, such as anthropometric, inflammatory, or hormonal data.
Conclusion: The postprandial HTG level might be the best predictor of
improved insulin resistance in morbidly obese patients after bariatric
surgery. 2013 American Society for Metabolic and Bariatric Surgery.

Abstract
Introduction Evidence suggests a nephroprotective effect of urinary
alkalinization in patients at risk of acute kidney injury (AKI). Methods
In a multicenter, double-blind, RCT we enrolled 350 adult cardiac surgery
patients. At induction of anesthesia, patients received either 24 hours of
intravenous infusion of sodium bicarbonate (5.1 mmol/kg) or sodium
chloride (5.1 mmol/kg). The primary endpoint was the proportion of
patients developing AKI. Results Sodium bicarbonate increased urinary pH
(from 6.0 to 7.5, P <0.001). More patients in the bicarbonate group
(83/174 (47.7%)) developed AKI compared with control (64/176 (36.4%), OR =
1.60 (95% CI, 1.04 to 2.45); unadjusted P = 0.032). A greater
postoperative (Graph Presented) increase in urinary NGAL in patients
receiving bicarbonate infusion was observed compared with control (P =
0.011). The incidence of postoperative RRT was similar but hospital
mortality was increased in patients treated with bicarbonate compared with
chloride (11/174 (6.3%) vs. 3/176 (1.7%), OR 3.89 (1.07 to 14.2), P =
0.031). See Figure 1. Conclusion On this basis of our findings we do not
recommend the use of perioperative infusions of sodium bicarbonate to
reduce the incidence or severity of AKI in this patient group.

Abstract
Introduction Vasoplegic syndrome is a common complication after cardiac
surgery, with negative impact on patient outcomes and hospital costs.
Pathogenesis of vasodilatory phenomenon after cardiac surgery remains a
matter of controversy. Loss of vascular tone can be partly explained by
the depletion of neurohypophyseal arginine vasopressin stores. Vasopressin
is commonly used as an adjunct to catecholamines to support blood pressure
in refractory septic shock, but its effect on vasoplegic shock is unknown.
We hypothesized that the use of vasopressin would be more effective on
treatment of shock after cardiac surgery than norepinephrine, decreasing
the composite endpoint of mortality and severe morbidity. Methods In this
prospective and randomized, double-blind trial, we assigned patients who
had vasoplegic shock to receive either vasopressin (0.01 to 0.06 U/minute)
or norepinephrine (0.01 to 1 mug/kg/minute) in addition to open-label
vasopressors. All vasopressor infusions were titrated and tapered
according to protocols to maintain a target blood pressure. The primary
endpoint was major morbidity according to STS (30-day mortality,
mechanical ventilation >48 hours, mediastinitis, surgical re-exploration,
stroke, acute renal failure). Secondary outcomes were time on mechanical
ventilation, ICU and hospital stay, new infection, the time to attainment
of hemodynamic stability, occurrence of adverse events and safety. Results
A total of 300 patients underwent randomization, were infused with the
study drug (148 patients received vasopressin, and 152 norepinephrine),
and were included in the analysis. Patients who received vasopressin had a
lower rate of morbidity (23.5% vs. 34%, P = 0.001) as compared with the
norepinephrine group. The 30-day mortality rate was 6.1% in the
norepinephrine group and 4.6% in the vasopressin group (P = 0.570). There
were no significant differences in the overall rates of serious adverse
events (7.4% and 6.6%, respectively; P = 0.772). Conclusion Vasopressin
reduces major morbidity after cardiac surgery as compared with
norepinephrine among patients with cardiac surgery with vasoplegic shock.

Abstract
Introduction We hypothesized that goal-directed therapy (GDT) is not
associated with an increased risk of cardiac complications in high-risk,
noncardiac surgical patients. Patients with limited cardiopulmonary
reserve are at risk of mortality and morbidity after major surgery [1].
Augmentation of the oxygen delivery index (DO<sub>2</sub>I) with a
combination of intravenous fluids and inotropes (GDT) has been shown to
reduce the postoperative mortality and morbidity in high-risk patients
[2]. However, concerns regarding cardiac complications associated with
fluid challenges and inotropes used to augment cardiac output may deter
clinicians from instituting early GDT in the very patients who are more
likely to benefit. Methods Systematic search of MEDLINE, Embase and
CENTRAL databases for randomized controlled trials of GDT in high-risk
surgical patients. Studies including cardiac surgery, trauma, and
pediatric surgery were excluded to minimize heterogeneity. We reviewed the
rates of all cardiac complications, arrhythmias, acute myocardial
ischemia, and acute pulmonary edema. Meta-analyses were performed and
forest plots drawn using RevMan software. Data are presented as odd ratios
(ORs) (95% CIs), and P values. Results We identif ed 23 randomized
controlled trials including 2,219 patients, who reported cardiac
complications. GDT was associated with a reduction in total cardiovascular
complications (OR = 0.55 (0.39 to 0.78), P = 0.0007), and with a
significantly reduced incidence of arrhythmias (OR = 0.59 (0.38 to 0.91),
P = 0.02). GDT was not associated with an increase in acute pulmonary
edema (OR = 0.68 (0.42 to 1.10), P = 0.11) or acute myocardial ischemia
(OR = 0.70 (0.38 to 1.27), P = 0.23). Subgroup analysis of overall
cardiovascular complications revealed that the benefit is most pronounced
in patients receiving fluid and inotrope therapy (OR = 0.55 (0.34 to
0.89), P = 0.01) to achieve a supranormal oxygen delivery target (OR =
0.50 (0.32 to 0.79), P = 0.003), guided by the use of minimally invasive
cardiac outmonitoring (OR = 0.50 (0.33 to 0.77), P = 0.002). Conclusion
Perioperative, physiologically guided, GDT in high-risk surgical patients
is not associated and actually reduces postoperative cardiovascular
complications.

Abstract
Introduction A goal-directed resuscitation therapy (GDT) through
optimization of cardiac output reduces complications in noncardiac
surgeries. We investigated whether the implementation of a GDT protocol in
high-risk cardiac surgery with the use of LiDCO Rapid reduces
postoperative complications as compared with the standard of care. Methods
We performed a prospective and randomized study whereby consecutive
patients fulf lling one high-risk criteria (EuroSCORE >5, ejection
fraction <50%, recent myocardial infarction, unstable angina or
extracardiac arteriopathy) were allocated to GDT or conventional
hemodynamic therapy. We excluded patients with endocarditis, previous use
of dobutamine, need for IABP, high dose of vasopressors and emergency
surgery. The GDT protocol involved hemodynamic resuscitation aimed at a
target of a cardiac index >3 l/minute/m<sup>2</sup> through a three-step
approach: fluid therapy of 250 ml lactated Ringer's solution, dobutamine
infusion up to a dose of 20 mug/kg/minute, and red blood cell transfusion
to reach a hematocrit level above 28%. Results Twenty patients from the
GDT group were compared with 20 control patients. Both groups were
comparable concerning baseline characteristics and severity scores, except
for a higher prevalence of hypertension and heart failure in the GDT
group. Intraoperative data showed no difference regarding length of
extracorporeal circulation, fluid balance, transfusion or inotropic
requirement. Patients from the GDT group were given more fluids within the
first 8 hours as compared with the conventional group (1,250 ml vs. 500
ml, P <0.001). GDT patients showed a median ICU stay of 3 days (95% CI: 3
to 4) compared with 5 days in control patients (95% CI: 4 to 7). Moreover,
hospital stay was less prolonged in GDT patients (10 days vs. 14 days, P =
0.043). Inotropic dependence was lower in the GDT group (29 hours vs. 55
hours, P = 0.003) as well as the cumulative dobutamine dosage (8 vs. 19
mug/kg/day, P = 0.025). Also, GDT group presented a lower incidence of
infections, tachyarrithmias and acute renal failure (RIFLE R) when
compared with the control group. Conclusion A hemodynamic therapy tailored
to an optimized cardiac output reduced the length of ICU stay, vasoactive
drug requirement and postoperative complications. Acknowledgement Grants
