On- vs. Off-Pump CABG in Heart Failure Patients with Reduced Ejection Fraction (HFrEF): A Multicenter Analysis. Biomedicines 2023; 11:3043. [PMID: 38002044 PMCID: PMC10669606 DOI: 10.3390/biomedicines11113043] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 11/06/2023] [Accepted: 11/08/2023] [Indexed: 11/26/2023] Open
Abstract
OBJECTIVE This study aimed to compare postoperative outcomes and 30-day mortality in patients with reduced ejection fraction (<40%) who underwent isolated coronary artery bypass grafting (CABG) with (ONCAB) and without (OPCAB) the use of cardiopulmonary bypass. METHODS data from four university hospitals in Germany, spanning from January 2017 to December 2021, were retrospectively analyzed. A total of 551 patients were included in the study, and various demographic, intraoperative, and postoperative data were compared. RESULTS demographic parameters did not exhibit any differences. However, the OPCAB group displayed notably higher rates of preoperative renal insufficiency, urgent surgeries, and elevated EuroScore II and STS score. During surgery, the ONCAB group showed a significantly higher rate of complete revascularization, whereas the OPCAB group required fewer intraoperative transfusions. No disparities were observed in 30-day/in-hospital mortality for the entire cohort and the matched population between the two groups. Subsequent to surgery, the OPCAB group demonstrated significantly shorter mechanical ventilation times, reduced stays in the intensive care unit, and lower occurrences of ECLS therapy, acute kidney injury, delirium, and sepsis. CONCLUSIONS the study's findings indicate that OPCAB surgery presents a safe and viable alternative, yielding improved postoperative outcomes in this specific patient population compared to ONCAB surgery. Despite comparable 30-day/in-hospital mortality rates, OPCAB patients enjoyed advantages such as decreased mechanical ventilation durations, shorter ICU stays, and reduced incidences of ECLS therapy, acute kidney injury, delirium, and sepsis. These results underscore the potential benefits of employing OPCAB as a treatment approach for patients with coronary heart disease and reduced ejection fraction.

Long-Term Follow-Up of Device-Assisted Clampless Off-Pump Coronary Artery Bypass Grafting Compared with Conventional On-Pump Technique. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 19:275. [PMID: 35010535 PMCID: PMC8750984 DOI: 10.3390/ijerph19010275] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/21/2021] [Revised: 12/20/2021] [Accepted: 12/25/2021] [Indexed: 06/14/2023]
Abstract
STUDY OBJECTIVE To evaluate the long-term outcomes of clampless off-pump coronary artery bypass grafting (C-OPCAB) compared with conventional on-pump double clamping coronary artery bypass grafting (C-CABG). METHODS From October 2006 to December 2011, 366 patients underwent isolated coronary artery bypass grafting. After propensity score matching of preoperative variables, 143 pairs were selected who received C-OPCAB with the use of device-assisted PAS-Port proximal venous graft anastomoses or C-CABG, performed by the same surgeon experienced in both techniques. Data of the two groups of patients were retrospectively analyzed up to 14 years of follow-up. RESULTS As compared with C-OPCAB, in the C-CABG patients, the performed number of grafts per patient was higher (2.9 ± 0.5 vs. 2.6 ± 0.6, p-value 0.0001). At 14 years, overall survival, including in-hospital death, was 64 ± 4.7% for the C-OPCAB vs. 55 ± 5.5% for the C-CABG, freedom from overall MACCEs 51 ± 6.2% vs. 41 ± 7.7%, and from late cardiac death 94 ± 2.4% vs. 96 ± 2.2% (p-value not significant, for all comparisons). No significant statistical differences were observed in the actual rates of adverse events during follow-up. Independent predictors of survival were advanced age at operation (p-value 0.001) and a lower mean value of preoperative left ventricular ejection fraction (p-value 0.015). CONCLUSIONS Our single-center study analysis suggests that clampless OPCAB using device-assisted proximal anastomoses proved to be not inferior to double-clamping CABG in the long-term follow-up, provided that involved surgeons are familiar with both techniques. These conclusions are supported by a large and long-term follow-up period, eliminating potential bias, i.e., by means of the propensity score matching and analyzing single-surgeon experience.

Abstract
AIM Comparison of short and mid-term outcomes between off-pump CABG (OPCAB) and on-pump CABG (ONCAB) in patients older than 65 throughout a meta-analysis of randomized clinical trials (RCTs). EVIDENCE ACQUISITION A literature search was conducted using 3 databases. RCTs reporting mortality outcomes of OPCAB versus ONCAB among the elderly were included. Data on myocardial infarction, stroke, re-revascularization, renal failure and composite endpoints after CABG were also collected. Random effects models were used to compute statistical combined measures and 95% confidence intervals (CI). EVIDENCE SYNTHESIS Five RCTs encompassing 6221 patients were included (3105 OPCAB and 3116 ONCAB). There were no significant differences on mid-term mortality (pooled HR: 1.02, 95%CI: 0.89-1.17, p=0.80) and composite endpoint incidence (pooled HR: 0.98, 95%CI: 0.88-1.09, p=0.72) between OPCAB and ONCAB. At 30-day, there were no differences in mortality, myocardial infarction, stroke and renal complications. The need for early re-revascularization was significantly higher in OPCAB (pooled OR: 3.22, 95%CI: 1.28-8.09, p=0.01), with a higher percentage of incomplete revascularization being reported for OPCAB in trials included in this pooled result (34% in OPCAB vs 29% in ONCAB, p<0.01). CONCLUSIONS Data from RCTs in elderly patients showed that OPCAB and ONCAB provide similar mid-term results. OPCAB was associated with a higher risk of early rerevascularization. As CABG on the elderly is still insufficiently explored, further RCTs, specifically designed targeting this population, are needed to establish a better CABG strategy for these patients.

Abstract
OBJECTIVES Female gender and advanced age are regarded as independent risk factors for adverse outcomes after isolated coronary artery bypass grafting (CABG). There is paucity of evidence comparing outcomes of CABG between male and female octogenarians. We aimed to analyse in-hospital outcomes of isolated CABG in this cohort. METHODS All octogenarians that underwent isolated CABG, from January 2000 to October 2017, were included. A retrospective analysis of a prospectively collected cardiac surgery database (PATS; Dendrite Clinical Systems, Oxford, UK) was performed. A propensity score was generated for each patient from a multivariable logistic regression model based on 25 pre-treatment covariates. A total of 156 matching pairs were derived. RESULTS Five hundred and sixty-seven octogenarians underwent isolated CABG. This included 156 females (mean age 82.1 [SD: 0.9]) and 411 males (mean age 82.4 [SD: 2.1 years]). More males were current smokers (P = 0.002) with renal impairment (P = 0.041), chronic obstructive pulmonary disease (P = 0.048), history of cerebrovascular accident (P = 0.039) and peripheral vascular disease (P = 0.027) while more females had New York Heart Association class 4 (P = 0.02), left ventricular ejection fraction 30-49% (P = 0.038) and left ventricular ejection fraction <30% (P = 0.049). On-pump, CABG was performed in 140 males and 52 females (P = 0.921). There was no difference in in-hospital mortality (5.4% vs 6.4%; P = 0.840), stroke (0.9% vs 1.3%; P = 0.689), need for renal replacement therapy (17.0% vs 13.5%; P = 0.732), pulmonary complications (9.5% vs 8.3%; P = 0.746) and sternal wound infection (2.7% vs 2.6%; P = 0.882). The outcomes were comparable for the propensity-matched cohorts. CONCLUSIONS No gender difference in outcomes was seen in octogenarians undergoing isolated CABG.

Abstract
Background A hybrid surgery method, on-pump beating heart coronary artery bypass graft (ON-BH CABG), is supposed to be a promising technology for coronary artery revascularization. Here, we conducted a comprehensive meta-analysis of the data derived from published studies on ON-BH CABG and conventional on-pump coronary artery bypass graft (C-CABG) to compare their short-term and long-term clinical outcomes. Methods We searched major electronic databases and 24 studies incorporating 6,862 patients (1,847 ON-BH CABG and 5,015 C-CABG) were included eventually, and 9 studies of them were focusing on high-risk patients. Results Compared with ON-BH CABG, C-CABG was associated with a higher risk in early mortality [odds ratio (OR), 1.45; 95% confidence interval (CI), 1.09 to 1.93; P=0.01], myocardial infarction (MI) (OR, 2.60; 95% CI, 1.41 to 4.78; P<0.01), low output syndrome (LOS) (OR, 2.56; 95% CI, 1.55 to 4.23; P<0.01), renal failure (OR, 1.84; 95% CI, 1.38 to 2.44; P<0.01). In contrast, there was no significant difference in long-term survival [hazard ratio (HR), 1.08; 95% CI, 0.81 to 1.43; P=0.60]. In systematic analysis of the studies in high-risk patients, ON-BH CABG showed a lower risk in terms of early mortality, intra-aortic balloon pump (IABP) usage, renal failure, hemodialysis, MI and pulmonary complication. No significant difference was observed in the long-term survival between ON-BH CABG and C-CABG. Conclusions With experienced and adept surgical team and mature ON-BH technology, ON-BH CABG may reduce the risk of postoperative death and complications in some patients. It might be an attractive alternative for high-risk patient populations.

Abstract
OBJECTIVES Severe left ventricular dysfunction (LVD) is associated with increased risk following coronary artery bypass grafting (CABG). Due to a dearth of reports on the choice of CABG technique in patients with LVD, this study aims to compare the outcomes of off-pump CABG (OPCAB) and conventional CABG (ONCAB) in such patients. METHODS Retrospective single-centre propensity-matched analysis comparing early- and long-term outcomes of OPCAB and ONCAB in patients with severe LVD. Primary outcome was long-term all-cause mortality. RESULTS Between 2002 and 2014, a total of 1161 consecutive patients with severe LVD underwent isolated CABG [442 patients underwent OPCAB and 719 ONCAB (430 matched pairs)]. Incomplete revascularization was observed more frequently among OPCAB than ONCAB patients (35.3% vs 21.6%; P < 0.01). The overall 30-day mortality was 5% and was comparable between the matched groups [OR 0.64 (0.34-1.22); P = 0.18]. OPCAB patients had shorter median hospital stay (11 vs 12 days; P = 0.02) and lower packed red blood cell transfusion rates [2.7 (2.21-3.19) vs 4.4 (3.56-5.24); P < 0.01]. Estimated adjusted survival was 86.0% vs 85.8%, 69.1% vs 65.5% and 59.9% vs 49.1% at 1, 5 and 10 years for OPCAB and ONCAB patients, respectively (P = 0.99). Long-term risk of mortality was similar between groups [hazard ratio (HR) 0.94 (0.66-1.32); P = 0.7]. Incomplete revascularization was weakly associated with increased risk of long-term all-cause mortality [HR 1.33 (0.99-1.77); P = 0.05]. CONCLUSIONS OPCAB is safe and effective in patients with severe LVD. Although incomplete revascularization is more commonly observed in patients undergoing OPCAB, it is not associated with increased late mortality.

Abstract
OBJECTIVES Recent data suggested that off-pump coronary artery bypass (OPCAB) may carry a higher risk for mortality in the long term when compared to on-pump coronary artery bypass (ONCAB). We, therefore, compared long-term survival and morbidity in patients undergoing ONCAB versus OPCAB in a large single-centre cohort. METHODS A total of 8981 patients undergoing isolated elective/urgent coronary artery bypass grafting between January 2009 and December 2019 were analysed. Patients were stratified into 2 groups (OPCAB n = 6649/ONCAB n = 2332). The primary end point was all-cause mortality. Secondary endpoints included repeat revascularization, stroke and myocardial infarction. To adjust for potential selection bias, 1:1 nearest neighbour propensity score (PS) matching was performed resulting in 1857 matched pairs. Moreover, sensitivity analysis was applied in the entire study cohort using multivariable- and PS-adjusted Cox regression analysis. RESULTS In the PS-matched cohort, 10-year mortality was similar between study groups [OPCAB 36.4% vs ONCAB 35.8%: hazard ratio (HR) 0.99, 95% confidence interval (CI) 0.87-1.12; P = 0.84]. While 10-year outcomes of secondary endpoints did not differ significantly, risk of stroke (OPCAB 1.50% vs ONCAB 2.8%: HR 0.51, 95% CI 0.32-0.83; P = 0.006) and mortality (OPCAB 3.1% vs ONCAB 4.8%: HR 0.65, 95% CI 0.47-0.91; P = 0.011) at 1 year was lower in the OPCAB group. In the multivariable- and the PS-adjusted model, mortality at 10 years was not significantly different (OPCAB 34.1% vs ONCAB 35.7%: HR 0.97, 95% CI 0.87-1.08; P = 0.59 and HR 1.01, 95% CI 0.90-1.13; P = 0.91, respectively). CONCLUSIONS Data do not provide evidence that elective/urgent OPCAB is associated with significantly higher risks of mortality, repeat revascularization, or myocardial infarction during late follow-up when compared to ONCAB. Patients undergoing OPCAB may benefit from reduced risks of stroke and mortality within the first year postoperatively.

Off-pump coronary artery bypass grafting for patients with severely reduced ventricular function-A justified strategy? J Card Surg 2021; 37:7-17. [PMID: 33547711 DOI: 10.1111/jocs.15259] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 10/07/2020] [Accepted: 10/12/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND AND AIM Low ejection fraction (EF) has been identified as a main risk factor for perioperative complications and mortality after coronary artery bypass grafting (CABG). The purpose of this study was to compare the efficacy and early as well as midterm outcomes of off-pump CABG (OPCAB) and conventional CABG (ONCAB) surgery in patients with reduced EF. METHODS We performed a retrospective review of patient demographics, preoperative risk factors, operative and postoperative outcomes of patients with left ventricular EF (LV-EF) ≤35%, who underwent CABG at our institution between January 2015 and December 2017. Propensity score and multivariate logistic regression analysis were used to compare risk adjusted outcomes between groups. RESULTS Overall, 111 consecutive CABG-patients with LV-EF ≤ 35% underwent either ONCAB (46 patients, 41.4%) or OPCAB surgery (65 patients, 58.6%). There was no difference in early mortality (5% vs. 7.5%, p = .64) between groups. After propensity score matching, OPCAB-patients required significantly less re-sternotomies for bleeding (20% vs. 2.5%, p = .03) and consequently received significantly less blood transfusions (57.5% vs. 32.5%, p = .03). Fewer OPCAB-patients experienced low cardiac output syndrome (22.5% vs. 42.5%, p = .06) and suffered from postoperative delirium (22.5% vs. 42.5%, p = .06). There were no differences in completeness of revascularization between groups (median 1 (1.0-1.33; 1.0-1.33) OPCAB versus median 1 (1-1.33; 0.67-2) ONCAB, p = .95). Survival after 6 months, one year and three years was similar for ONCAB- and OPCAB-patients (ONCAB 92.3%, 89.4%, and 89.4% vs. OPCAB 89.8%, 85.7%, and 82.1%; p = .403). More ONCAB-patients needed a coronary re-intervention during follow-up (8.6% vs. 2.3%, p = .402). CONCLUSION OPCAB-surgery is a safe and effective option for patients with reduced EF. Furthermore, it does not come at the expense of less complete revascularization or increased coronary re-intervention during early follow-up.

Individual Versus Sequential Saphenous Vein Grafts for on-Pump Coronary Artery Bypass Grafting - Does Smaller Coronaries in Indians Affect Graft Choice? - A Mid-Term Patency Comparison Study. J Saudi Heart Assoc 2020; 33:109-116. [PMID: 34183906 PMCID: PMC8143723 DOI: 10.37616/2212-5043.1245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 03/04/2021] [Accepted: 03/06/2021] [Indexed: 11/20/2022] Open
Abstract
PURPOSE Although multiarterial grafting or bilateral mammary artery use is being increasingly emphasized for contemporary coronary artery bypass grafting (CABG) practice, saphenous vein graft (SVG) still accounts for 80% of all CABG conduits (Park et al., 2020) [1]. In India, both the individual and sequential saphenous grafting techniques are used arbitrarily, and there has not been a study that compares the mid-term patency of these two. This is specially relevant in view of smaller coronaries in Indians than the Caucasian counterparts. This study aims to compare the patency for on pump CABG's. METHODS In the present study, 323 patients underwent either sequential (group A, N = 151 grafts, each graft having two anastomoses each) or individual (group B, N = 344 grafts) saphenous vein CABG, between February 2014 and June 2017. The SVG anastomoses were created on obtuse marginal (OM1/OM2) and posterior descending artery (PDA). The graft patency of the vein grafts as well as the left internal mammary artery were assessed by serial coronary angiograms. RESULTS Results were evaluated at 6 months, 1, 2 and 3 years post operatively. Group A showed a higher graft patency at 3 years at 80.8%, and group B, 67.1% (P = 0.002). Also, anastomoses on sequential conduits had overall better patency rates at three years (77.2% vs 67.2%, P = 0.005). The groups showed similar results at one year post operatively. CONCLUSIONS Sequential bypass grafts were associated with superior mid-term patency compared with individual grafts. These findings suggest the more favourable results of sequential bypass grafting to be attributed to the enhanced flow haemodynamics.

Abstract
The enormous majority of previous reports focused on evaluating the safety and efficacy of sequential saphenous vein (SV) coronary bypass grafting; however, no reports to date have revealed concern regarding the impacts of the number of distal anastomoses of sequential SV grafting on graft patency after coronary artery bypass grafting (CABG). This single-center retrospective study aimed to evaluate the impacts of three versus two distal anastomoses per single SV conduit on SV graft patency after off-pump CABG, and to determine the independent risk factors for sequential SV graft failure.From January 2011 to December 2014, 1320 eligible patients were assigned to either a triple group (three distal anastomoses of sequential SV grafting, n = 758) or a double group (two distal anastomoses of sequential SV grafting, n = 562). The primary endpoint was over a 2-year follow-up SV graft failure after off-pump CABG.The triple and double group received a similar total patency rate of sequential SV conduits (86.5% versus 87.1%, P = 0.757). The number of distal anastomoses of sequential SV grafting (three versus two) was not a predictive factor for the follow-up graft failure of sequential SV conduits (HR = 0.91, 95% CI: 0.66-2.29, P = 0.137). Moreover, the two groups received a similar follow-up survival freedom from repeat revascularization (χ2 = 1.881, log-rank P = 0.170).Three versus two distal anastomoses per single SV conduit received a similar SV graft patency. The number of distal anastomoses of sequential SV grafting was not an independent risk factor for graft failure.

Abstract
For many years, the concept of "complete revascularization" (CR) was considered an absolute truth in coronary surgery with improved long-term survival and a lower rate of reintervention. This was derived from early publications which showed a survival benefit for patients undergoing coronary artery bypass grafting (CABG) who received CR. Many advances in the field of coronary revascularization have been made in the years that passed since those publications, including more frequent use of percutaneous coronary intervention (PCI) in patients with multivessel disease (MVD). This has led some to question the importance of CR and raise the option of "reasonable incomplete revascularization" (IR) for selected patients. The definition of CR is variable in the literature with the two most common definitions being an anatomical (revascularization of all coronary segments with stenosis and larger than a predefined size) and a functional definition (where revascularization is considered complete if all ischemic and viable territories are reperfused). No randomized control trials have been conducted to compare complete versus IR, and a significant proportion of data is based on post hoc analysis of data from randomized control trials and registries. Multiple studies have proven that CR is achieved more frequently with CABG then with PCI. A review of the available data from the past three to four decades shows a trend toward improved results with CR, regardless of the reperfusion strategy chosen. This should impact the heart team discussion when choosing a revascularization strategy and impact the surgical decision making while preforming CABG. IR can be part of a hybrid revascularization strategy or be reserved for rare cases where the cost of achieving CR much outweighs the benefit.

Abstract
BACKGROUND Remote ischemic preconditioning (RIPC) has been demonstrated to prevent organ dysfunction in cardiac surgery patients. However, recent large, prospective, multicenter, randomized controlled trials (RCTs) had controversial results. Thus, a meta-analysis of RCTs was performed to investigate whether RIPC can reduce the incidence of acute myocardial infarction (AMI), acute kidney injury (AKI), and mortality in adult cardiac surgery patients. METHODS Study data were collected from Medline, Elsevier, Cochrane Central Register of Controlled Trials and Web of Science databases. RCTs involving the effect of RIPC on organ protection in cardiac surgery patients, which reported the concentration or total release of creatine kinase-myocardial band, troponin I/troponin T (TNI/TNT) after operation, or the incidence of AMI, AKI, or mortality, were selected. Two reviewers independently extracted data using a standardized data extraction protocol where TNI or TNT concentrations; total TNI released after cardiac surgery; and the incidence of AKI, AMI, and mortality were recorded. Review Manager 5.3 software was used to analyze the data. RESULTS Thirty trials, including 7036 patients were included in the analyses. RIPC significantly decreased the concentration of TNI/TNT (standard mean difference [SMD], -0.25 ng/mL; 95% confidence interval [CI], -0.41 to -0.048 ng/mL; P = .004), creatine kinase-myocardial band (SMD, -0.22; 95% CI, -0.07-0.35 ng/mL; P = .46), and the total TNI/TNT release (SMD, -0.49 ng/mL; 95% CI, -0.93 to -0.55 ng/mL; P = .03) in cardiac surgery patients after a procedure. However, RIPC could not reduce the incidence of AMI (relative risk, 0.89; 95% CI, 0.70-1.13; P = .34) and AKI (relative risk, 0.88; 95% CI, 0.72-1.06; P = .18), and there was also no effect of RIPC on mortality in adult cardiac surgery patients. Interestingly, subgroup analysis showed that RIPC reduced incidence of AKI and mortality of cardiac surgery patients who received volatile agent anesthesia. CONCLUSIONS Our meta-analysis demonstrated that RIPC reduced TNI/TNT release after cardiac surgery. RIPC did not significantly reduce the incidence of AKI, AMI, and mortality. However, RIPC could reduce mortality in patients receiving volatile inhalational agent anesthesia.

Abstract
Background The efficacy and safety of off-pump coronary artery bypass grafting (OPCAB) in emergency revascularization remains controversial despite its widespread use. The aim of our study was to examine the applicability and safety of OPCAB in patients who were indicated for emergency surgery. Methods This single-center study reviewed the indication, operative data, and early and long-term outcomes of 113 patients (mean age, 67.2±9.0 years; logistic EuroSCORE, 14.3±13.5) who underwent emergency OPCAB from January 2003 to December 2014 and were followed up (94.6% completion rate) for a mean 51.1±40.3 (range, 1-135) months. Results Emergency OPCAB was associated with favorable surgical outcomes (number of distal anastomoses per patient, 3.04±0.87; internal thoracic artery (IMA) use, 98.2%; complete revascularization, 79.6%) and in-hospital outcomes (mortality, 5.3%; low cardiac output syndrome, 5.3%; stroke, 2.7%; pulmonary complications, 8.8%; renal failure, 11.5%). Only five patients (4.4%) required on-pump conversion. The 10-year outcomes were also acceptable (survival, 75.4%±5.6%; major cerebral and cardiovascular events, 52.1%±1.8%). The multivariate risk factors for late mortality were peripheral vascular disease (HR 2.95, 95% CI: 1.11-11.83), cardiogenic shock (HR 3.67, 95% CI: 1.35-9.96), and incomplete revascularization (HR 3.41, 95% CI: 1.06-14.26). When patients were separated by whether the procedure was performed early (<2010) or late (≥2010) in the study period, the late period cohort had better outcomes despite containing higher-risk patients. Conclusions Our study suggests that emergency OPCAB can be performed safely and effectively with good hospital outcomes and adequate long-term results. OPCAB strategy can be considered as a good option in emergency revascularization.

Abstract
Background and aim There is some controversy about survival of coronary endarterectomy (CE) patients, so the current study aims to compare short and long term survival of patients undergoing off pump coronary artery bypass graft (OPCAB) with and without coronary endarterectomy. Patients and methods we performed a retrospective analysis of data on patients undergoing OPCAB and CE between 2011 and 2012. Preoperative, perioperative and postoperative data collected from data bank. Follow-up information was obtained from telephone contact mean time 37.13 ± 23.82 months after surgery. Early and late outcomes were compared by univariate and Kaplan-Meier analysis. Result OPCAB was performed in 474 patients, which 69 of them had a CE. The mean long term survival was similar between OPCAB (56.28 ± 0.61) and OPCAB + CE (55.54 ± 1.3) groups (p = 0.66). Multiple Cox regression shows that age, gender, BMI, EF and angina were significant predictors of mortality. Patients undergoing CE have a long term intensive care unit (ICU) stay (51.31 ± 5.59 vs 37.23 ± 0.88, P = 0.015) and blood transfusion was higher in CE group (650.62 ± 110 vs. 324.71 ± 22, P = 0.001). Conclusion The current study demonstrates that results of CE are acceptable with respect to short and long -term survival. Patients undergoing CE required long term ICU stay and higher blood transfusion.

Abstract
BACKGROUND Despite many studies comparing on- versus off-pump coronary artery bypass graft (CABG), there is no consensus as to whether one of these techniques offers patients better outcomes. METHODS We searched PubMed from inception to June 30, 2015, and identified additional studies from bibliographies of meta-analyses and reviews. We identified 42 randomized controlled trials (RCTs) and 31 rigorously adjusted observational studies (controlling for the Society of Thoracic Surgeons-recognized risk factors for mortality) reporting mortality for off-pump versus on-pump CABG at specified time points. Trial data were extracted independently by 2 researchers using a standardized form. Differences in probability of mortality (DPM) were estimated for the RCTs and observational studies separately and combined, for time points ranging from 30 days to 10 years. RESULTS RCT-only data showed no significant differences at any time point, whereas observational-only data and the combined analysis showed short-term mortality favored off-pump CABG (n = 1.2 million patients; 36 RCTs, 26 observational studies; DPM [95% confidence interval (CI)], -44.8% [-45.4%, -43.8%]) but that at 5 years it was associated with significantly greater mortality (n = 60,405 patients; 3 RCTs, 5 observational studies; DPM [95% CI], 10.0% [5.0%, 15.0%]). At 10 years, only observational data were available, and off-pump CABG showed significantly greater mortality (DPM [95% CI], 14.0% [11.0%, 17.0%]). CONCLUSIONS Evidence from RCTs showed no differences between the techniques, whereas rigorously adjusted observational studies (with >1.1 million patients) and the combined analysis indicated that off-pump CABG offers lower short-term mortality but poorer long-term survival. These results suggest that, in real-world settings, greater operative safety with off-pump CABG comes at the expense of lasting survival gains.

Abstract
BACKGROUND Elective open heart surgery is associated with troponin release in some cases due to myocyte necrosis. OBJECTIVES The aim of this study was to measure cardiac troponin I (cTnI) preoperatively in elective CABG after remote ischemic preconditioning. METHODS Twenty-eight patients were selected for elective CABG. They were randomized to receive remote ischemic preconditioning (induced by three 5-min cycles of inflation with a pneumatic tourniquet and 5-min deflation between inflation episodes as reperfusion). OUTCOMES Primary outcomes were cardiac troponin I levels at 6 and 24 hours after the procedure, and the secondary outcomes included creatine phosphokinase, lactate dehydrogenase, and serum creatinine levels. Hemodynamic changes were evaluated between the treatment and control groups. RESULTS Cardiac troponin I at 6 hours after preconditioning was significantly lower compared to the control group (P = 0.036), and after 24 hours, there was still a significant difference between the two groups (P < 0.05). CONCLUSIONS Remote ischemic preconditioning reduces ischemic biomarkers during coronary artery bypass graft and attenuates procedure-related cardiac troponin I release and eventually reduces cardiovascular events such as myocardial infarction, chest pain, and hemodynamic changes after cardiac surgery.

Abstract
AIMS The effects of off-pump CABG (OFF-CABG) versus on-pump CABG (ON-CABG) in diabetic patients remain controversial. The aim of our study was to compare mortality and postoperative morbidity between OFF-CABG and ON-CABG for diabetic patients. METHODS Electronic databases including PubMed, EMBASE and Cochrane Library for studies investigating clinical outcomes of OFF-CABG versus ON-CABG in diabetic patients were searched, collecting data from inception until June 2016. We pooled the odds ratios from individual studies and performed heterogeneity, quality assessment and publication bias analysis. RESULTS A total of 543,220 diabetic patients in 10 studies were included. The overall mortality (OR, 0.87; 95% CI, 0.58-1.31; p = 0.50) was comparable between the OFF-CABG and ON-CABG. OFF-CABG was associated with significantly fewer cerebrovascular accidents (OR, 0.45; 95% CI, 0.31-0.65; p < 0.0001), bleeding complications (OR, 0.59; 95% CI, 0.43-0.80; p < 0.001) and pulmonary complications. However, no differences in myocardial infarction (OR, 0.76; 95% CI, 0.52-1.12; p = 0.16), renal failure (OR, 0.74; 95% CI, 0.50-1.11; p = 0.14) and other postoperative morbidity outcomes were found. CONCLUSIONS OFF-CABG significantly reduces the incidence of postoperative cerebrovascular accidents and bleeding complications compared with ON-CABG in diabetic patients. No differences were found regarding mortality, myocardial infarction and renal failure between these two techniques. Our study suggests that OFF-CABG may be an optimal strategy for diabetic patients although adequately powered randomized trials are needed to further verify the finding.

Abstract
For patients with coronary artery disease (CAD), in combination with diabetes mellitus, diffuse multivessel coronary artery lesions are common. Such patients are prone to a more rapid progression of atherosclerosis, significantly increasing the need for myocardial revascularization. The choice of an optimal approach determines the prognosis and course of CAD. The results of randomized trials show that the use of percutaneous coronary interventions with drug-eluting stents is appropriate for patients with one or two coronary artery lesions, but that coronary artery bypass graft surgery is preferred in cases of multivessel disease and significantly reduces the risk of long-term adverse events. It should also be noted that the use of modern generations of stents allows the achievement of comparable results in terms of long-term mortality, which was most convincingly demonstrated in patients with one or two vascular lesions.

Abstract
Objective. To investigate the effects of diabetes mellitus (DM) in patients undergoing off-pump coronary artery bypass grafting (OPCAB). Method. A total of 728 patients with DM and 1380 patients without DM who underwent OPCAB treatment from March 2012 to April 2015 were reviewed. The effects of DM on intraoperative variables and postoperative complications were determined using propensity score analysis. Results. Two well-matched subgroups were selected using propensity score analysis (DM = 728, no-DM = 728) to compare the perioperative outcome. The duration of the ICU stay, in hours (55.2 ± 53.0 versus 49.29 ± 51.30, P < 0.05), postoperative new-onset atrial fibrillation (20.9% versus 14.97%, P < 0.05), and postoperative infection (9.2% versus 4.67%, P < 0.05) were greater in DM patients, as indicated by univariate analysis. Conclusion. OPCAB was found to be effective in DM patients, but postoperative infection and postoperative new-onset atrial fibrillation were found to be more likely to occur in DM patients than in other patients. DM was found to be a powerful risk factor for postoperative infection and postoperative new-onset atrial fibrillation.

Abstract
Background Controversy persists regarding the use of coronary endarterectomy (CE) in patients with severe coronary artery disease. We compared the comorbidities and perioperative characteristics of patients undergoing coronary artery bypass grafting (CABG) with and without CE. Methods This study was performed in two private hospitals in Shiraz, Iran from May 2010 to December 2011 on 967 patients who underwent CABG without CE and 84 patients who underwent CABG with CE (the CE+ group). After follow-up at 9.66±3.65 months post-surgery, 28 patients from the CE+ group underwent angiography to evaluate the patency of grafts and native coronary vessels. Results Patients in the CE+ group had a more prevalent history of diabetes (48% vs. 36%) and number of diseased vessels (2.88±0.39 vs. 2.70±0.85). The overall hospital mortality was 1.8%, and no significant difference was observed between the two groups. In the 28 patients who underwent reangiography, 113 vessels were bypassed and 29 endarterectomies were performed, mostly on the left anterior descending artery (12 endarterectomies) and the right coronary artery (8 endarterectomies). In the endarterectomized vessels, a 66% patency rate was found in both the grafts and the native vessels. The native coronary vessels were more likely to be patent when the left internal mammary artery was used as a conduit than when a saphenous vein bypass graft was used. Conclusion The lack of a significant difference in postoperative complications in patients who underwent CABG with or without CE may indicate that CE does not expose patients to a higher risk of complications. Since most of the endarterectomized vessels were shown to be patent during the follow-up period, we propose that endarterectomy is a viable option for patients with severely diseased vessels.

Abstract
OBJECTIVE Despite increasing recognition of the benefits of off-pump coronary artery bypass grafting (CABG), concerns persist regarding its impact on long-term mortality and freedom from reintervention. In this study, we assessed the impact of off-pump CABG on long-term outcomes. METHODS From January 2002 to December 2002, a total of 307 consecutive patients who underwent isolated multivessel off-pump CABG at our institution were compared with a control group of 397 patients who underwent multivessel on-pump CABG during the same period. Perioperative data were prospectively collected and compared. In addition, univariate and risk-adjusted comparisons between the two groups were performed at 10 years. RESULTS After adjusting for clinical covariates, off-pump CABG did not emerge as a significant independent predictor of long-term mortality [hazard ratio (HR), 0.91; 95% confidence interval (CI), 0.70-1.12], readmission to hospital for cardiac cause (HR, 0.96; 95% CI, 0.78-1.10), or the need for reintervention (HR, 0.93; 95% CI, 0.87-1.05). CONCLUSIONS At long-term follow-up, off-pump CABG remains a safe and effective myocardial revascularization strategy with no adverse impact on survival or freedom from reintervention.

Abstract
OBJECTIVE Octogenarians, as the fastest growing stratum of the population and with the highest prevalence of coronary artery disease, are being increasingly referred for coronary artery bypass grafting (CABG). The general perception is that the presence of comorbidities and the propensity for neurological injury expose them to a higher risk for mortality and morbidity after conventional on-pump CABG, and therefore, off-pump CABG should be preferentially offered to octogenarians to improve outcomes. This study evaluates the in-hospital outcomes and predictors of mortality and stroke in octogenarians undergoing on- and off-pump CABG at our institution. METHODS From January 2000 to December 2010, a total of 290 octogenarians underwent off-pump (n = 217) and on-pump (n = 73) CABG. Their data were prospectively entered into the cardiac surgery database (Patients Analysis & Tracking System; Dendrite Clinical Systems, Ltd, Oxford, England, United Kingdom) and analyzed retrospectively. Outcome measures included in-hospital mortality, major complications, and length of stay. Multivariate analysis was performed to identify predictors of combined outcome of in-hospital mortality and stroke. RESULTS The mean ± SD age of the patients was 82 ± 2.0 years. Preoperative demographics were similar for the on-pump and off-pump groups. The patients who underwent off-pump CABG had a lower number of distal anastomoses performed compared with the patients who underwent on-pump CABG [mean difference, 0.2; 95% confidence interval (CI), 0.02-0.4; P = 0.03]. However, the ratio of grafts (received/needed) was the same in both groups. In-hospital mortality for the entire cohort was 7.2%, with no significant difference between the groups for death (6.0% vs 11.0%; P = 0.08), stroke (2.8% vs 2.8%; P = 1.0), other major complications, and length of hospital stay. Independent predictors of combined outcome identified from the multiple logistic model included heart failure [odds ratio (OR), 4.4; 95% CI, 1.5-13.0; P = 0.008], diabetes (OR, 2.6; 95% CI, 1.0-6.0; P = 0.046), nitrate infusion (OR, 2.9; 95% CI, 1.1-8.0; P = 0.04), postoperative renal failure requiring hemofiltration (OR, 8.6; 95% CI, 3.5-21.1; P < 0.001), and postoperative ventricular arrhythmias (OR, 7.3; 95% CI, 1.9-27.8; P = 0.009). CONCLUSIONS Both on-pump and off-pump CABG are reasonable revascularization strategies in octogenarians. Careful patient selection and individualized treatment decisions can minimize postoperative mortality and morbidity in octogenarians undergoing on- and off-pump CABG.

Abstract
There are two basic ways of performing coronary artery bypass graft surgery (CABG): on pump CABG and off pump CABG. Off pump CABG is relatively a newer procedure to on-pump CABG and does not require the use of the cardiopulmonary bypass machine. On pump CABG is the more traditional method of performing bypass surgery. However its resultant inflammatory effects cause renal dysfunction, gastrointestinal distress and cardiac abnormalities which have forced the surgeons to look for alternatives to the procedure. An extensive literature search revealed that on pump CABG causes better revascularization as compared to off pump CABG while off pump CABG has a much lower post operative morbidity and mortality especially in high risk patients. We suggest that the technique used should depend on the ease of the surgeon doing the operation as both the methods seem almost equally efficient according to the review.

Abstract
OBJECTIVES To determine whether remote ischemic preconditioning (RIPC) reduces myocardial injury, mortality, morbidity, and resource utilization in cardiac surgery. DESIGN Meta-analysis of controlled clinical trials. The primary outcome was cardiac troponin I (cTnI) concentrations. Secondary outcomes included cardiac troponin T (cTnT) concentrations, myocardial infarction, stroke, renal failure requiring hemodialysis, atrial fibrillation, inotropic score, mechanical ventilation time, length of intensive care unit stay, length of hospital stay, and death. SETTING University hospitals. PATIENTS Adult and pediatric patients undergoing cardiac surgery, including coronary artery bypass grafting, valve procedures, and correction of congenital cardiac anomalies. INTERVENTIONS Remote ischemic preconditioning through limb ischemia. MEASUREMENTS AND MAIN RESULTS Nineteen randomized trials involving 1,235 patients were included in the meta-analysis. The cTnI concentrations at 6 (or 4-8) hours postoperatively and the total cTnI released after surgery showed a statistically significant reduction in the RIPC group compared with a control group (weighted mean difference [WMD] -2.03 ug/L, 95% confidence interval [CI] -3.25 to -0.82 ug/L, p = 0.001; WMD -65.74 ug/L*h, 95% CI -107.88 to -23.61 ug/L*h, p = 0.002, respectively). There were no differences in mortality, morbidity, and resource utilization between groups. CONCLUSIONS Current evidence suggests that RIPC reduces cardiac troponin I release in patients undergoing cardiac surgery. The clinical significance of these observations merits further investigation.

Abstract
Recently published evidence has raised concerns about worse late mortality and increasing need for reintervention after off-pump coronary artery bypass grafting. We undertook this study to assess the impact of off-pump coronary artery bypass grafting on survival and freedom from reintervention at 10 years. From January 2002 to December 2002, 307 consecutive patients who had isolated multivessel off-pump coronary artery bypass grafting at our institution were compared to a control group of 397 patients that underwent multivessel on-pump coronary artery bypass grafting during the same period. In addition, univariate and risk-adjusted comparisons between the two groups were performed at 10 years. Kaplan-Meier survival was similar for the two cohorts. After adjusting for clinical covariates, off-pump coronary artery bypass grafting did not emerge as a significant independent predictor of long-term mortality (Hazard Ratio 0.91; 95% Confidence Interval 0.70-1.12), readmission to hospital for cardiac cause (Hazard Ratio 0.96; 95% Confidence Interval 0.78-1.10), or the need for reintervention (Hazard Ratio 0.93; 95% Confidence Interval 0.87-1.05). Off-pump coronary artery bypass grafting compared with on-pump coronary artery bypass grafting does not adversely impact survival or freedom from reintervention at a 10-year follow-up.

Surgical revascularization remains the standard of care for many patients. Off-pump coronary artery bypass grafting (OPCAB) without cardiopulmonary bypass (CPB) has evolved during the past 20 years, and as such can significantly reduce the occurrence of neurological complications. While avoiding the aortic cross-clamping required in conventional on-pump techniques, OPCAB results in a lower incidence of stroke. However, clamp-related risk of stroke remains if partial or side-biting clamps are applied for proximal anastomoses. Others and we have demonstrated that no-touch 'anaortic' approaches avoiding any clamping during off-pump procedures via complete in situ grafting result in significantly reduced stroke rates when compared with partial clamping. Therefore, OPCAB in situ grafting has been proposed as the 'standard of care' to reduce neurological complications. However, this technique may not be applicable to for every patient as the use of free grafts (arterial or venous) requiring proximal anastomosis is often still necessary to achieve complete revascularization. In these situations, proximal anastomosis can be performed without a partial clamp by using the HEARTSTRING device, and over the last few years, considerable evidence has arisen supporting the impact of HEARTSTRING-enabled anastomosis to significantly minimize atheroembolism and neurological complications when compared with partial- or side-bite clamping. This paper provides a systematic overview and technical information about the combination of OPCAB and clampless strategies using the HEARTSTRING for proximal anastomosis to reduce stroke to levels reported for percutaneous coronary intervention.

Abstract
<p><b>Objective:</b> A common perception is that use of pedicled bilateral internal mammary arteries (BIMA) increases the risk of sternal wound complications in diabetic patients undergoing coronary artery bypass grafting (CABG). The purpose of this study was to compare the in-hospital outcomes of CABG using pedicled BIMA in diabetic and nondiabetic patients.</p><p><b>Methods:</b> From September 1998 to September 2010, 390 consecutive diabetic patients and 519 nondiabetic patients underwent isolated off-pump CABG using pedicled BIMA. The 2 groups had comparable preoperative demographics except for a higher prevalence of acute myocardial infarction (18.9% versus 6.1%, <i>P</i> = .01), peripheral vascular disease (17.2% versus 2.7%, <i>P</i> = .001), an ejection fraction <30% (17.7% versus 8.5%, <i>P</i> = .02), and chronic renal failure (4.5% versus 0.9%, <i>P</i> = .01) in the diabetic patients.</p><p><b>Results:</b> The operative mortality rate of the diabetic patients was comparable to that of the nondiabetic patients (2.8% versus 2.1%, <i>P</i> = .87). The in-hospital outcomes, including occurrence of superficial and deep sternal wound infections, were similar except for an increased occurrence of wound infection at the vein harvest site (6.6% versus 1.1%, <i>P</i> = .04) and a need for hemofiltration (11.8% versus 2.1%, <i>P</i> = .02) in the diabetic patients.</p><p><b>Conclusions:</b> Pedicled BIMA use is associated with comparable incidences of sternal wound complications and other outcomes in diabetic patients and nondiabetic patients. Strict perioperative glycemic control, adherence to meticulous closure technique, and postoperative management of surgical wounds can make pedicled BIMA use a default strategy for diabetic patients.</p>

Abstract
BACKGROUND Surgical revascularization is the most appropriate therapy for patients with significant left main coronary-artery disease (LMD). An incidence of perioperative stroke remains an issue when compared to the early outcomes to percutaneous coronary intervention (PCI). This study evaluates the safety and impact of standardized "clampless" OPCAB techniques, composed of either complete in situ grafting or "clampless" device enabled techniques for stroke reduction in patients undergoing surgical revascularization for LMD. METHODS Between 1999 and 2009, 1031 patients with LMD underwent myocardial-revascularization at our institution. Of these, 507 patients underwent "clampless" OPCAB and 524 patients underwent conventional on-pump CABG (ONCABG). Data-collection was performed prospectively and a propensity-adjusted regression-analysis was applied to balance patient characteristics. LMD was defined as a stenosis >50% and endpoints were mortality, stroke, a cardiac-composite (including death, stroke and myocardial-infarction); a non-cardiac composite and complete-revascularization. RESULTS In OPCAB patients, the cardiac composite (3.0% vs. 7.8%; propensity-adjusted (PA)OR=0.27; CI95% 0.12-0.65; p=0.003) as well as the occurrence of stroke (0.4% vs. 2.9%; PAOR=0.04; CI95% 0.003-0.48; p=0.012) were significantly lower while the mortality-rate was well comparable between groups (1.8% vs. 2.5%; PAOR=0.44; CI95% 0.11-1.71; p=0.24). The non-cardiac composite was also significantly decreased after OPCAB (8.9% vs. 19.7%; PAOR=0.55; CI95% 0.34-0.89; p=0.014) and complete revascularization was achieved for similar proportions in both groups (95.1% vs. 93.7%; p=0.35). CONCLUSIONS This study shows the superiority of OPCAB for patients with LMD with regards to risk-adjusted outcomes other than mortality. A "clampless OPCAB strategy", effectively reduces stroke yielding similar early outcomes as PCI.

Abstract
OBJECTIVES Despite increasing recognition that off-pump coronary artery bypass surgery and sequential grafting strategy individually are associated with improved outcomes, concerns persist regarding the safety and efficacy of combining these 2 techniques. We compared in-hospital and midterm outcomes for off-pump multivessel sequential and conventional coronary artery bypass grafting. METHODS From September 1998 to September 2008, 689 consecutive patients received off-pump multivessel sequential coronary artery bypass grafting performed by a single surgeon. These patients were propensity matched to 689 patients who underwent off-pump coronary artery bypass grafting without sequential anastomoses. A retrospective analysis of prospectively collected perioperative data was performed. In addition, medical notes and charts of all the study patients were reviewed. The mean duration of follow-up was 5.1 ± 2.0 years. RESULTS The major in-hospital clinical outcomes in the sequential and control groups were found to be similar. After adjusting for clinical covariates, sequential grafting was not an independent predictor of in-hospital adverse events (odds ratio [OR], 1.18; 95% confidence interval [CI], 0.86-1.50; P = .31), medium-term mortality (hazard ratio [HR], 1.26; 95% CI, 1.06-1.32; P = .92), and readmission to hospital (HR, 1.12; 95% CI, 0.96-1.20; P = .80). Sequential grafting was an independent predictor of receiving more than 3 distal anastomoses (OR, 7.46; 95% CI, 4.27-11.45; P < .0001). Risk-adjusted survival was 89% for sequential grafting patients and 88% for conventional grafting patients (P = .96) during the medium-term follow-up. CONCLUSION Our analysis confirms the short- and midterm safety and efficacy of off-pump sequential coronary artery bypass grafting.

Abstract
Remote ischaemic preconditioning (RIPC) gained attention as a possibility to reduce myocardial injury after a subsequent sustained episode of myocardial ischaemia. This prospective randomized study was carried out to assess whether RIPC reduces myocardial injury in coronary artery bypass grafting patients. Eighty patients were assigned to remote preconditioning or control treatment. Ischaemic preconditioning was induced by three 5-min cycles of upper limb ischaemia and reperfusion after anaesthesia induction. Haemodynamic and markers of myocardial damage were analysed preoperatively and over 48 h postoperatively. The cardiac index was higher immediately after remote preconditioning in the main group. There were no differences in other haemodynamic, troponin I and creatine kinase-MB concentrations at any time point between groups. Thus, short-term remote preconditioning improves haemodynamics and does not reduce myocardial injury after coronary artery bypass surgery. Further study of high-risk patients may be needed to fully evaluate the clinical effect of RIPC.

Abstract
BACKGROUND A severely impaired left ventricular ejection fraction (EF) (30%) increases the risk of surgical myocardial revascularization. We evaluated the safety and feasibility of off-pump coronary artery bypass (OPCAB) surgery in patients with a severely decreased EF. METHODS We compared 79 patients with an EF ≤30% (group A) with 863 patients with an EF >30% (group B) who underwent myocardial revascularization between 2003 and 2008. The relationship between EF and outcome after OPCAB was assessed by univariate and logistic regression analyses. A composite end point was constructed from 30-day mortality, renal failure, length of stay in the intensive care unit (ICU) >2 days, neurologic complications, and use of an intra-aortic balloon pump (IABP). Additionally, the completeness of revascularization was assessed. RESULTS The mortality rates for groups A and B were comparable (1.3% and 2.0%, respectively; P = .55), and the 2 groups did not differ with regard to serious postoperative complications, such as stroke (2.5% versus 1.4% for groups A and B, respectively; P = .42), peripheral neurologic complications (2.5% versus 0.7%, P = .14), renal failure (0% versus 1.1%, P = 1.00), use of an IABP (1.3% versus 0.8%, P = .50), ICU length of stay >2 days (17.7% versus 19.6%, P = .77). Similarly, groups A and B did not differ with regard to ventilation time (11.2 ± 12.7 hours versus 12.4 ± 15.5 hours, P = .82), indicating similar postoperative courses for the 2 groups of patients. In contrast, the composite end point occurred significantly more frequently in group A (43.0% versus 29.7%, P = .02), a result driven by the increased rate of rethoracotomy for bleeding in that group (11.4% versus 2.9%, P = .001). The 2 groups were similar with respect to the total number of grafts used per patient (3.82 ± 0.89 versus 3.63 ± 1.01, P = .10) and the completeness of revascularization (94% versus 93%, P = .49). CONCLUSION A standardized OPCAB approach is safe for patients with a severely decreased EF, and its use does not come at the cost of less complete revascularization.

Abstract
Recognition of the potentially deleterious effects of esxtracorporeal circulation led to off-pump coronary artery surgery (OPCAB) experiencing a surge in popularity in the initial decade after its conception. However, OPCAB has its own limitations and technical difficulties, such as coronary access, increased left ventricular size and reduced function, which may lead to the potential for suboptimal revascularization. As an alternative technique, miniaturized extracorporeal circulation (mECC) may provide a more controlled operative field in which the heart may be manipulated whilst minimizing the inflammatory, coagulopathic and haemodilutional effects of cardiopulmonary bypass. In this review, we outline the proposed benefits of the mECC system, discuss the pitfalls associated with mECC, and directly compare mECC to ‘off-pump’ coronary surgery for a variety of clinical and non-clinical outcomes.

Abstract
Objective Coronary artery bypass grafting (CAB) on elderly patients presenting with multivessel coronary artery disease has become routine in modern day operating rooms. The aim of our study was to compare short- and long-term outcomes in octogenarian patients undergoing off-pump CAB (OPCAB) versus on-pump CAB (ONCAB). Methods A propensity-adjusted, retrospective review of patients older than 80 years who underwent primary CAB from January 1996 to September 2008 at our institution's hospitals was performed. Nine hundred thirty-seven patients were divided into two groups: OPCAB (n = 540) or ONCAB (n = 397). A propensity score was calculated based on 29 preoperative risk factors to adjust for selection bias when comparing the groups for differences in death, stroke, myocardial infarction incidence, and their composite (major adverse cardiac events). Long-term survival status was determined by cross-referencing patient records with the Social Security Death Index. Logistic regression analysis and Cox proportional hazards analysis were used to determine group differences in short- and long-term survival, respectively, adjusted for the propensity score. Kaplan-Meier curves were fit to estimate 10-year survival. Results The mean age (OPCAB: 82.9 ± 2.8 years vs ONCAB: 82.3 ± 2.4, P = 0.003) and male sex (OPCAB: 292/540, 54.1% vs ONCAB: 220/397, 55.4%, P = 0.68) were clinically similar between groups. Although the ejection fraction (OPCAB: 52.1 ± 12.5% vs ONCAB: 50.6 ± 13.1, P = 0.10) were similar between groups, the mean number of distal anastomoses [OPCAB: 2.7 ± 1.0 (median 3) vs ONCAB: 3.4 ± 0.9 (median 3), P < 0.001] were less in the OPCAB group. The median postoperative length of stay was 7 days for OPCAB group and 6 for the ONCAB group (P = 0.31). The Society of Thoracic Surgery predicted risk of in-hospital mortality was similar for OPCAB (5.4%) and ONCAB (5.3%) patients (P = 0.81). However, observed in-hospital mortality was improved for patients in the OPCAB group (OPCAB: 15/540, 2.8% vs ONCAB: 37/397, 9.3%, P = 0.007). Ten-year survival was similar between groups (OPCAB: 28.8% vs ONCAB: 26.3%, P = 0.22). Conclusions In this series, OPCAB reduced the incidence of in-hospital mortality compared with ONCAB. Long-term mortality was similar between groups.

Abstract
Introduction: The applicability of off-pump coronary-artery bypass (OPCAB) in patients who present as emergency remains controversial. Herein, we explore the efficacy and safety of OPCAB in patients who were indicated for emergency surgery. Materials and Methods: Between 2002 and 2007, a total of 282 patients underwent OPCAB, of which 68 were presented as emergency. This cohort (group A) was compared to 68 patients who had traditional on-pump coronary artery bypass grafting (CABG, group B) under emergency indications during the same period of time. Baseline demographics, intraoperative data and postoperative outcomes were analysed. Results: Preoperative demographics were comparable in both groups. Mortality during the first 30 days was comparable in both groups and no stroke occurred in the whole series. Patients in group A had significantly less pulmonary complications (4.4% vs 14.7%, P= 0.04), less ventilation time (30.3 ± 33.6 hours vs 41.5 ± 55.4 hours, P = 0.18) and were less likely to have prolonged ventilation, (19.1% vs 35.3%, P = 0.03). Similarly, OPCAB patients had less postoperative renal-failure/dysfunction (5.9% vs 8.8%, P = 0.51) and required less inotropic support (66.2% vs 88.2%, P = 0.002), bloodtransfusions (23% vs 86.8%, P <0.0001), and atrial- (17.6% vs 35.3%, P = 0.02) or ventricular-pacing (17.6% vs 41.2%, P = 0.002). Although the number of diseased vessels was comparable in both groups, patients in group A received less distal anastomoses. (2.78 ± 1.19 vs 3.41 ± 0.89, P = 0.002). Similarly, complete revascularisation was achieved less frequently in group A (76.5% vs 94.1%, P = 0.004). Conclusion: OPCAB strategy is a safe and efficient in emergency patients with reasonable good short-term postoperative outcomes.
