Abstract
Currently, coronary artery disease (CAD) has been identified as the leading cause of mortality in Malaysia and in other countries worldwide. Genetic predisposition and comorbidities such as hypertension and diabetes mellitus, gender, lifestyle, and several other risk factors can contribute to the development of CAD. Pharmacological and surgical treatments play a vital role in improving the quality of life of patients with CAD. New surgical techniques and continuous interventions have been introduced to improve the treatment outcome. Recently, cardiothoracic teams from Universiti Teknologi MARA (UiTM) and Universiti Sains Malaysia (USM) have conducted a 2-day live workshop on off-pump coronary artery bypass (OPCAB) surgery. In this brief communication, we share the highlights and clinical tips of the OPCAB surgery gained from the collaboration.

Abstract
AIM The guideline for coronary artery revascularization replaces the 2011 coronary artery bypass graft surgery and the 2011 and 2015 percutaneous coronary intervention guidelines, providing a patient-centric approach to guide clinicians in the treatment of patients with significant coronary artery disease undergoing coronary revascularization as well as the supporting documentation to encourage their use. METHODS A comprehensive literature search was conducted from May 2019 to September 2019, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Collaboration, CINHL Complete, and other relevant databases. Additional relevant studies, published through May 2021, were also considered. STRUCTURE Coronary artery disease remains a leading cause of morbidity and mortality globally. Coronary revascularization is an important therapeutic option when managing patients with coronary artery disease. The 2021 coronary artery revascularization guideline provides recommendations based on contemporary evidence for the treatment of these patients. The recommendations present an evidence-based approach to managing patients with coronary artery disease who are being considered for coronary revascularization, with the intent to improve quality of care and align with patients' interests.

Abstract
BACKGROUND While several randomized trials have shown conflicting results regarding the comparative effectiveness of on- and off-pump coronary arterial bypass grafting (CABG), research on long-term outcomes in large-scale, real-world clinical settings are limited. We sought to examine the comparative effectiveness of on- and off-pump CABG in a real-world clinical setting. METHODS Using the nationwide claims database of the Korean National Health Insurance Service, we identified patients who underwent isolated CABG from 2004 to 2013. Propensity-score matching with multivariable adjustment was used to assemble a cohort of patients with similar baseline characteristics. RESULTS Among 23,828 patients, 12,639 in the off-pump (53.0%) and 11,189 in the on-pump (47.0%) groups were enrolled. After matching, 6,483 pairs were included in the final analysis. At 30 days, there was no significant difference in adjusted mortality between the off- and on-pump groups (hazard ratio [HR], 1.00; 95% confidence interval [CI], 0.87-1.16). During long-term follow-up (100% complete; median 5.3yrs, maximum 13.2yrs), however, off-pump CABG was associated with a higher risk of mortality than on-pump CABG (HR, 1.09; 95% CI, 1.03-1.15). The risks of myocardial infarction (MI) (HR, 1.3; 95% CI, 1.16-1.45) and repeat revascularization (HR, 1.50; 95% CI, 1.37-1.63) were also significantly higher in the off-pump CABG group than in the on-pump CABG group, while the stroke risk was similar inter-groups (HR, 0.99; 95% CI, 0.87-1.13). CONCLUSIONS In this contemporary, nationwide, clinical practice claim registry, off-pump CABG was associated with higher long-term risks of mortality, MI, and repeat revascularization than on-pump CABG.

Anesth Pain Med 2020; 10:e100517. [PMID: 32754433 PMCID: PMC7352649 DOI: 10.5812/aapm.100517] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2019] [Revised: 03/10/2020] [Accepted: 03/16/2020] [Indexed: 12/29/2022] Open
Abstract
Background Acute kidney injury (AKI) is one of the serious complications of cardiac surgery. It is worsened when accompanied by low cardiac output syndrome. Objectives In this study, we compared kidney function based on the KDIGO criteria in isolated on-pump and off-pump coronary artery bypass graft (CABG) surgery. Methods In this cohort study, 52 patients with LCOS were enrolled after on-pump (28 patients) and off-pump (24 patients) CABG. In the first six hours after ICU entrance, blood samples were taken for serum creatinine based on routine. For determining AKI after surgery, we used the KDIGO criteria as a primary endpoint. Also, some clinical parameters were recorded before, during, and after surgery. The data were analyzed by SPSS software, version 24, using paired and independent t-test, ANOVA, and Pearson correlation test and non-parametric tests such as Mann-Whitney and Kruskal-Wallis tests at a significance level of P < 0.05. Results There was no significant difference in age (P = 0.3) and gender (P = 0.57) between the two groups. Among cardiac disease risk factors, only hypertension (P = 0.02) had a significant difference between the two groups, but AKI in patients with hypertension did not show a significant difference (P = 0.09). In paraclinical parameters, serum creatinine showed a significant difference before and after surgery in on-pump (P < 0.001) and off-pump (P = 0.007) groups. Also, this parameter had a significant difference at 6 h, 12 h, 24 h, and 48 h after surgery between the on-pump and on-pump groups. The AKI incidence showed a significant difference between the two groups (P < 0.001). Conclusions The incidence of AKI was more in on-pump patients than in off-pump patients. Also, a significant difference was observed between their clinical parameters. Thus, to improve the patients’ clinical outcomes and lower the health costs, we suggest that patients with a high risk of LCOS be followed up after CABG, especially on-pump CABG.

Abstract
Purpose Redo coronary artery bypass grafting (CABG) can be one of the most technically challenging operations in cardiac surgery. The coronary disease is more advanced, and the coronary targets may be suboptimal. In addition, the patients are typically older and sicker compared to those undergoing primary CABG. Methods A literature review focused on the epidemiology, operative techniques, and outcomes associated with redo CABG. Results The frequency of redo CABG relative to total CABG procedures has been decreasing over time. From 2000 to 2009, redo CABG decreased from 6.0 to 3.4% of all CABG procedures reported to the STS Adult Cardiac Surgery Database (STS ACSD) and currently stands at 2%. Risks associated with reoperations include diabetes and renal dialysis. Perioperative mortality for redo CABG is reported to be as high as three times that of primary CABG, but this risk is reduced with experience. Careful preoperative planning including quality imaging and precise surgical technique coupled with meticulous myocardial protection contributes to good outcomes. Experience is important in optimizing outcomes. Conclusions Redo CABG is a complicated operation and surgical experience, and appropriate perioperative strategies are essential for achieving optimal outcomes.

Abstract
It was a randomized trial, and 308 patients undergoing revascularization were randomly assigned: 155 to off-pump coronary artery bypass (OPCAB) and 153 to on-pump coronary artery bypass (ONCAB). End points were freedom from death, myocardial infarction, revascularization, and cerebrovascular accidents. The rates for 10-year, event-free survival for ONCAB versus OPCAB were 69.6% and 64%, (hazard ratio [HR]: 0.88; 95% confidence interval [CI] 0.86-1.02; P = .41), respectively. Adjusted Cox proportional hazard ratio was similar (HR: 0.92; 95% CI 0.61-1.38, P = .68). A difference occurred between the duration of OPCAB and ONCAB, respectively (4.9 ± 1.5 vs 6.6 ± 1.1 h, P < .001). Statistical differences occurred between OPCAB and ONCAB in the length of intensive care unit (ICU) stay (20 ± 2.5 vs 48 ± 10 hours, P < .001), time to extubation (5.5 ± 4.2 vs 10.2 ± 3.5 hours, P < .001), hospital stay (6.7 ± 1.4 vs 9.2 ± 1.3 days, P < .001), higher incidence of atrial fibrillation (AF; 33 vs 5 patients, P < .001), and blood requirements (46 vs 64 patients, P < .001). Grafts per patient was higher in ONCAB (3.15 vs 2.55 grafts, P < .001). No difference existed between the groups in primary composite end points at 10-year follow-up. Although OPCAB surgery was related to a lower number of grafts and higher incidence of AF, it had no effects related to long-term outcomes.

Abstract
BACKGROUND Data from randomized trials evaluating the efficacy of on- versus off-pump coronary artery bypass grafting remain inconclusive, particularly in high-risk populations. AIMS The aim of this study is to compare the outcomes associated with on- versus off-pump coronary artery bypass grafting among high-risk patients. METHODS We performed a meta-analysis of randomized control trials comparing on- versus off-pump coronary artery bypass grafting, focusing on high-risk populations. Studies focusing on "high-risk" features: European System of Cardiac Operative Risk Evaluation (EuroSCORE) ≥ 5, age > 70 years, preexisting renal insufficiency, history of stroke(s), and the presence of left ventricular dysfunction were included. MEDLINE, Scopus, and Embase were searched for all publications between January 1, 2000 and August 1, 2016, using the following terms: on-pump, off-pump, coronary artery bypass, high-risk, left ventricular dysfunction, elderly, aged, and renal insufficiency. Endpoints included cardiovascular and all-cause mortality, non-fatal myocardial infarction, stroke, need for revascularization, renal failure, and length of hospital stay. RESULTS Nine studies incorporating 11,374 patients with a mean age of 70 years were selected. There was no statistical difference in cardiovascular mortality, all-cause mortality, non-fatal myocardial infarction, and renal failure between the two groups. There was a decrease in further revascularization at 1 year with on-pump (OR 0.67 (0.50-0.89)). However, there was an increase in length of hospital stay by 2.24 days (p = 0.03) among the on-pump group with no difference in stroke (OR 1.34 (1.00-1.80)). CONCLUSIONS On-pump is associated with a decreased risk of additional revascularization by 1 year. However, this appears to be a cost of longer hospitalization.

Abstract
We compared stroke rates associated with coronary artery bypass grafting (CABG), both on-pump and off-pump, and percutaneous coronary intervention (PCI) with both drug-eluting stent (DES) and bare-metal stent (BMS) and the impact on 30-day and 1-year all-cause mortality. The Myocardial Infarction Data Acquisition System database was used to study patients who had on-pump CABG (n = 47,254), off-pump CABG (n = 19,118), and PCI with BMS (n = 46,641), and DES (n = 115,942) in New Jersey from 2002 to 2012. Multiple logistic and Cox proportional hazard models were used to compare the risk of stroke and mortality. Adjustments were made for demographics, year of hospitalization, and co-morbidities. The rate of postprocedural stroke was lowest with DES (0.5%), followed by BMS (0.6%), off-pump CABG (1.3%), and on-pump CABG (1.8%). After adjustment, on-pump CABG had a higher risk of stroke compared with off-pump (odds ratio 1.36, 95% CI 1.18 to 1.56, p <0.0001). DES had lower risk of stroke compared with off-pump CABG (odds ratio 0.64, 95% CI 0.55 to 0.74, p <0.0001). There was a significant excess risk of 1-year mortality due to the interaction between stroke and procedure type (on-pump vs off-pump CABG and PCI with DES vs BMS; p value for interaction = 0.02). In conclusion, in this retrospective analysis of nonrandomized data from a statewide database, PCI with DES was associated with the lowest rate of postprocedural stroke, and off-pump CABG had a lower rate of postprocedural stroke than on-pump CABG; there was an excess 1-year mortality risk with on-pump versus off-pump CABG and with DES versus BMS in patients with stroke.

Abstract
The superiority of either off-pump (OPCAB) or on-pump (ONCAB) coronary artery bypass grafting (CABG) remains unclear despite a large body of literature evidence comparing the two approaches. The potential advantages of avoiding cardiopulmonary bypass (CPB), minimizing aortic manipulation and maintaining pulsatile flow may be associated with reduced inflammatory responses and embolic events. Numerous studies compared OPCAB with ONCAB and the cumulative data have been presented in meta-analyses of both randomized and observational studies. Although there is an abundance of data with respect to the operative morbidity and mortality and the short-term outcomes associated with these two strategies, not much is known about how they impact long-term survival and recurrence of myocardial ischaemic events. Recent studies and meta-analyses have focused on long-term survival and major secondary outcomes in OPCAB vs. ONCAB within the general population. Significant limitations in methodology, however, have raised concerns about the strength of several randomized trials with restrictive inclusion criteria that reduced the populations to those at low risk only, thus creating result bias. Here, we present a review of the best available evidence with a focus on long-term outcomes.

Abstract
PURPOSE OF REVIEW This review will examine the current role of off-pump coronary artery bypass (OPCAB) surgery compared with on-pump coronary artery bypass (ONCAB) surgery for the revascularization of ischemic myocardium. RECENT FINDINGS Recent studies have confirmed earlier findings that OPCAB is associated with less grafts per patient and less complete revascularization, and increased incidence of recurrent angina and need for repeat revascularization procedures, and more frequent rehospitalization for cardiac-related issues. OPCAB does not prevent postoperative renal dysfunction and is associated with worse long-term outcomes. Hospital costs are not reduced and are increased in those OPCAB patients who require intraoperative conversion to ONCAB procedures; however, when multiple arterial grafts are used and a complete revascularization is performed, OPCAB outcomes are equivalent to those of ONCAB procedures. SUMMARY OPCAB should only be performed by surgeons experienced in this technique in patients in whom a complete revascularization can be achieved; preferably with multiple arterial grafts.

Abstract
OBJECTIVES We aim to describe our experience in coronary artery bypass grafting (CABG) with or without cardiopulmonary bypass by comparing intraoperative and postoperative outcomes. METHODS From January 1993 to June 2013, 3097 patients underwent consecutive emergency and scheduled CABG surgery. A total of 1770 patients underwent on-pump CABG (ONCABG) and 1327 off-pump CABG (OPCABG). A propensity score matching was performed to identify appropriate matched-pair patients; univariable and multivariable logistic regression analyses were performed to assess significant predictors of hospital and 30-day morbidity and mortality composite end-points. Morbidity composite end-point was defined as any renal, pulmonary, cardiovascular and neurological complication that occurred during hospital stay. We collected all-cause mortality data during the study period. RESULTS We identified 1004 patients in each group. There were no significant differences in thirty day mortality, 2.8 vs 3.8%, in OPCABG and ONCABG, respectively (P = 0.21). Cardiovascular, neurological, respiratory and renal complications were more frequent in the ONCABG group: 13.9 vs 8.7% (P < 0.001), 3.9 vs 2.2% (P = 0.03), 13.5 vs 7.5% (P < 0.001), 7.1 vs 5.3% (P = 0.095), respectively. The long-term all-cause mortality rate was 12.3 vs 12.9% in the OPCABG versus ONCABG group (P = 0.42), respectively. In both uni- and multivariable analysis preoperative renal failure, chronic obstructive pulmonary disease and ONCABG were independent predictors of mortality and morbidity composite end-points. CONCLUSIONS OPCABG is associated with less postoperative morbimortality and shorter hospital and intensive care unit length of stay. ONCABG resulted as an independent predictor of morbidity and mortality composite end-point. No statistically significant differences were observed in long-term all-cause mortality between groups.

Abstract
The off-pump literature is divided into three eras: the “early phase” with results favouring off-pump surgery supported with randomized control trials (RCTs) mainly from Bristol, UK; an “intermediate phase” dominated by the results of the ROOBY trial and finally a more “contemporary phase” whereby the off/on-pump argument is unsettled. Although the literature has failed to project an overall superiority of off-pump versus on-pump surgery, nevertheless, small randomized control trials and large meta-analysis studies are concluding that the incidence of a stroke is less than 1 % when an aortic off-pump techniques (especially the non-touch technique) are advocated in patients with diseased ascending aorta. Furthermore, off-pump combined with hybrid procedures may lead to a reduction of adverse outcome in the aged high-risk population with concomitant poor left ventricular function and co-morbidities. The current review attempts to bring an insight onto the last ten years knowledge on the on/off-pump debate, with an aim to draw some clear conclusions in order to allow practitioners to reflect on the subject.

Abstract
BACKGROUND Diabetes is increasing at an alarming rate, affecting nearly 8% of the population. Previous studies have demonstrated a potential benefit for surgical over interventional revascularization in diabetics. However, randomized clinical trials comparing coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) many not accurately reflect current clinical practice. We therefore undertook a prospective registry of coronary revascularization (CR) in diabetic patients with CABG, on-pump and off-pump, and PCI with bare-metal and drug-eluting stents to determine long-term clinical outcomes. METHODS All patients undergoing isolated CR in 8 community hospitals were enrolled. Follow-up was obtained after 5 to 8 years; all mortalities were checked against the Social Security Death Index. The ST-elevation myocardial infarction and salvage patients were excluded. Propensity matching was used to account for differences between PCI and CABG groups. Survival curves were derived using Kaplan-Meier methods, whereas hazard ratios and cumulative hazards were calculated using the Cox proportional hazard model. RESULTS Of the 3,156 patients in the registry, there were 1,082 diabetics; 334 CABG and 748 PCI. Due to the differences in baseline characteristics between the 2 groups, propensity score matching was used to achieve clinically comparable groups of 240 patients each. In matched patient groups mortality was more common in the PCI group with an odds ratio (OR) of 0.60 (95% confidence interval [CI] 0.39% to 0.93%; p = 0.023). Similarly, occurrence of any major cardiac adverse event (MACE) (mortality, non-fatal myocardial infarction, or revascularization) was more frequent in the PCI group with an OR of 0.57 (95% CI 0.31% to 0.70%, p < 0.001). Kaplan-Meier event-free survival of matched groups was significantly improved in the CABG versus PCI group (p = 0.001). CONCLUSIONS In the current era of on-pump and off-pump CABG surgery and bare-metal and drug-eluting stents, this registry which unselectively records all non-ST elevation myocardial infarction patients undergoing coronary revascularization, diabetic patients benefit from improved long-term survival and reduced MACE with CABG versus PCI. These findings corroborate recent evidence from prospective randomized trials and thus provide clinically relevant validation of their broad applicability to diabetics with extensive coronary artery disease in need of revascularization.

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
Cardiac surgery is inseparably linked to the activation of innate immunity cells recognizing danger signals of both endogenous and exogenous origin via pattern recognition receptors such as TLR receptors. Therefore, we followed by flow cytometry TLR2 and TLR4 expression on blood monocytes and granulocytes of patients who underwent coronary artery bypass grafting using beating heart surgery (off-pump, n = 34), with use of standard cardiopulmonary bypass (CPB), (on-pump, n = 30), and miniinvasive CPB (mini on-pump, n = 25), respectively, before, during surgery, and up to 7th postoperative day. TLR2 and TLR4 expression both on monocytes and granulocytes was significantly diminished already at the end of CPB being highly significantly decreased at the end of surgery in all patients’ groups. TLR2 and TLR4 expression reached preoperative value at the 1st postoperative day being significantly higher at the 3rd postoperative day. Using intracellular staining we found the peak of TLR2 and TLR4 expression inside of monocytes and granulocytes at the first postoperative day in a subgroup of on-pump patients. In conclusion, TLR2 and TLR4 expression is significantly modulated in patients undergoing coronary artery bypass grafting as a part of adaptive homeostatic mechanisms induced by major surgery. The very surgical trauma is responsible for TLR2 and TLR4 modulation. Surprisingly, cardiopulmonary bypass itself was little contributing to the modulation of TLR2 and TLR4 expression.

Abstract
Objectives Intraoperative assessment of coronary artery bypass grafts (CABG) anastomotic quality can be performed using transit-time flowmetry (TTF). The aim of this study was to compare on- versus off-pump coronary graft TTF and early postoperative outcomes. Materials and methods Between January 2009 and January 2010, 521 distal graft flows were assessed using TTF measurements in 253 consecutive patients undergoing primary isolated CABG surgery. Data were analyzed using multilevel models accounting for clustering among surgeons and grafts performed in the same patient. Results Mean age was 66 ± 10 years and 22% were female (n = 55) with 34% diabetics (n = 86) and 40% pre-operative myocardial infarction (MI) (n = 101). The surgeries were performed off-pump in 67% (n = 170) with sequential vein grafts in 57% (n = 144) of patients. Off-pump patients had higher pre-operative left ventricular ejection fractions (LVEF), fewer urgent surgeries, fewer distal anastomoses, and fewer sequential vein grafts (all p<0.001). Intra-operative coronary graft TTF measurements were lower in sequential vein grafts performed off-pump versus on-pump. More patients in the on-pump group needed milrinone or dobutamine 24-48 h postoperatively (p = 0.005). Independent predictors of lower TTF included female gender and off-pump surgery, whereas predictors of better TTF were pre-operative MI, larger coronary diameter at the site of the distal anastomosis, and sequential vein grafting. Conclusions Lower intra-operative TTF measurements were found in sequential vein grafts in offpump CABG. However, off-pump patients experienced similar short-term outcomes compared to on-pump patients.

Abstract
AIM The aim of this retrospective observational study was to investigate the effect of on-pump versus off-pump coronary artery bypass grafting (CABG) for patients with coronary artery diseases (CAD). METHODS A retrospective observational study was performed using a propensity score analysis in 290 consecutive patients undergoing CABG between April 2009 and March 2014, of them, 54 patients undergoing off-pump CABG (OPCABG) were matched with 54 patients undergoing on-pump CABG (ONCABG) by propensity score. The perioperative complications and hospital mortality were documented. RESULTS Preoperative characteristics were comparable in both groups following propensity matching. Postoperative myocardial infarction (MI) incidence was lower in OPCABG group than in ONCABG group (3.7% vs. 14.8%, P=0.046); both hospital mortality and the major complications rates were similar in the two groups after propensity adjustment for preoperative characteristics. CONCLUSIONS The perioperative complications are similar in both off-pump and on pump CABG groups, the short-term effect of OPCABG is similar to that of ONCABG.

Abstract
Background The aim of the present study was to evaluate and compare postoperative short-term, mid-term and long-term outcomes of coronary artery bypass surgery performed with or without cardiopulmonary bypass in patients with a low European System for Cardiac Operative Risk Evaluation score. Methods A retrospective analysis of 478 consecutive low risk patients undergoing coronary bypass surgery between January 2002 and December 2007 was performed. Of these patients, 83 cases had undergone on-pump and 395 cases had undergone off-pump coronary bypass surgery. The patients were assessed in terms peri-operative complications, survival, mortality due to cardiac events, need for rehospitalization and repeated coronary revascularization. Results There was no significant difference between the two groups in terms of preoperative characteristics, except for chronic obstructive pulmonary disease. The number of distal anastomosis per patient was significantly lower in the off-pump group than in the on-pump group (2.66 ± 0.74 vs. 3.21 ± 0.85, p < 0.001). Early mortality rates were similar in both groups (1.01% for the off-pump group and 1.2% for the on-pump group, p = 0.687). Neurological complications were significantly lower in the off-pump group than in the on-pump group (1.1% vs. 6%, p = 0.01). The mean follow-up period was 80 ± 19.1 months (range, 3–112 months). The need for revascularization during long-term follow-up was 10.1% in the off-pump group and 7.2% in the on-pump group (p = 0.416). The 5-year survival was 95.2 ± 1.1% and 95.5 ± 2.7% in the off-pump and on-pump groups, respectively (p = 0.8), whereas the 7-year survival was 91.9 ± 1.6% and 84.7 ± 6.8% in the off-pump and on-pump groups, respectively (p = 0.274). The 5-year revascularization-free period was 89.5 ± 1.6% and 89.7 ± 3.5% in the off-pump and on-pump groups, respectively (p = 0.785). The 7-year revascularization-free period was 71.1 ± 3.1% and 73.5 ± 7.3% in the off-pump and on-pump groups, respectively (p = 0.075). The 7-year event-free survival was 80.1 ± 2.2% and 73.4 ± 7.3% in the off-pump and on-pump groups, respectively (p = 0.377). Conclusions The present study demonstrated that off-pump cardiac surgery had advantages over on-pump cardiac surgery in the short term; however, both interventions had similar mid-term and long-term outcomes, when performed in low-risk patient.

The perioperative complications and hospital mortality were documented. RESULTS Preoperative characteristics were comparable in both groups following propensity matching. Postoperative myocardial infarction (MI) incidence was lower in OPCABG group than in ONCABG group (3.7% vs. 14.8%, P=0.046); both hospital mortality and the major complications rates were similar in the two groups after propensity adjustment for preoperative characteristics. CONCLUSIONS The perioperative complications are similar in both off-pump and on pump CABG groups, the short-term effect of OPCABG is similar to that of ONCABG.

Abstract
Coronary artery bypass grafting (CABG) continues to be one of the most commonly performed cardiac surgical procedures worldwide. Conventional CABG performed on cardiopulmonary bypass termed on-pump CABG is regarded as the gold standard. However, on-pump CABG results in several physiologic derangements including but not limited to thrombocytopenia, activation of complement factors, immune suppression, and inflammatory responses leading to organ dysfunction. Furthermore, manipulating an atherosclerotic ascending aorta during cannulation and cross-clamping can predispose to embolization and stroke risk. Recognition of these detrimental effects of on-pump CABG resulted in resurgence of off-pump CABG nearly two decades ago. Off-pump CABG since its resurgence has been a subject of intensive scrutiny and speculation. Despite numerous retrospective nonrandomized studies, prospective randomized trials, and meta-analyses validating the safety and efficacy of off-pump CABG, opponents of the technique have persistently demanded abandonment of off-pump CABG. Several misconceptions and misperceptions are used as an excuse for such demands. This review article examines published scientific evidence to evaluate these misperceptions and misconceptions about off-pump CABG.

Abstract
Extracorporeal circulation (ECC) has to ensure homeostasis of the patient and to minimize pathophysiological disorders inherent in the technique. However, we cannot dissociate it from the surgery and anesthesia knowing that the discipline involves a close partnership with these stakeholders. The purpose of this publication is to review the essential elements that at present can contribute to the quality of the CEC and suggest improvements and developments to be implemented in this area.

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.

Abstract
Background Data from randomized clinical trials comparing coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) may not accurately reflect current clinical practice, in which there is off‐label usage of drug‐eluting stents (DES). We undertook a prospective registry of coronary revascularization by CABG on‐ and off‐pump and PCI with bare‐metal stents (BMSs), DESs, or percutaneous transluminal coronary angioplasty (PTCA) to determine clinical outcomes. Methods and Results All patients undergoing isolated coronary revascularization in 8 community‐based hospitals were enrolled. Final follow‐up was obtained after 5 years by patient and/or physician contact and the Social Security Death Index. ST‐elevation myocardial infarction and salvage patients were excluded. Five or more years of follow‐up was obtained on 81.5% (3156) of the eligible patients—968 CABG patients (82.0%) and 2188 PCI patients (81.3%). Overall follow‐up was 63.5±27.9 months (median, 79.7 months). The incidence of initial major adverse cardiac events (MACEs) at follow‐up for CABG versus PCI was 29.2% versus 41.8% (P<0.001). Analysis of stent subgroups showed more events with BMSs (equivalent to PTCA alone) compared with DESs. All stents had more events than on‐ or off‐pump CABG groups. Using propensity score–matched groups, the odds ratio for CABG to PCI was 0.69 (95% confidence interval [CI], 0.56 to 0.85; P<0.001) for mortality and 0.58 (95% CI, 0.45 to 0.75; P<0.001) for any MACE. Conclusions In the current era of DES and off‐pump surgery, in a community hospital setting, comparable patients undergoing coronary revascularization appear to benefit from improved long‐term survival and reduced MACE with CABG versus PCI.

Abstract
Clinical trials of off-pump coronary artery bypass grafting (CABG) have largely excluded patients with CKD. Here, we sought to determine whether pump status affects outcomes in patients with CKD. Using a nonrandomized cohort of 742,909 non-emergent, isolated CABG cases, which included 158,561 off-pump cases, in the Society of Thoracic Surgery Database from 2004 through 2009, we evaluated the association between pump status (off-pump versus on-pump) and in-hospital death or incident renal replacement therapy (RRT) across strata of preoperative renal function. We used propensity methods to adjust patient- and center-level analyses for imbalances in baseline patient risk. Patients who received on-pump and off-pump CABG had similar mean age and distribution of preoperative estimated GFR (eGFR). In a propensity-weighted analysis, off-pump CABG was associated with a reduction in the composite in-hospital death or RRT, with patients having lower preoperative renal function exhibiting greater benefit, on average. The risk difference (on-pump minus off-pump) ranged from 0.05 (95% confidence interval, -0.06 to 0.16) per 100 patients for eGFR ≥ 90 ml/min per 1.73 m(2) to 3.66 (95% confidence interval, 2.14-5.18) per 100 patients for eGFR 15-29 ml/min per 1.73 m(2). Both component endpoints suggested the same trend. In summary, these data suggest that patients with CKD experience less death or incident RRT when treated with off-pump compared with on-pump CABG. The reduction in incident RRT, not death, drove this effect on the composite among patients with low eGFR. Prospective trials comparing these procedures in patients with impaired preoperative renal function are warranted.

Abstract
BACKGROUND Coronary artery bypass grafting (CABG) is performed both without and with cardiopulmonary bypass, referred to as off-pump and on-pump CABG respectively. However, the preferable technique is unclear. OBJECTIVES To assess the benefits and harms of off-pump versus on-pump CABG in patients with ischaemic heart disease. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library (Issue 1, 2011), MEDLINE (OVID, 1950 to February 2011), EMBASE (OVID, 1980 to February 2011), Science Citation Index Expanded on ISI Web of Science (1970 to February 2011) and CINAHL (EBSCOhost, 1981 to February 2011) on 2 February 2011. No language restrictions were applied. SELECTION CRITERIA Randomised clinical trials of off-pump versus on-pump CABG irrespective of language, publication status and blinding were selected for inclusion. DATA COLLECTION AND ANALYSIS For statistical analysis of dichotomous data risk ratio (RR) and for continuous data mean difference (MD) with 95% confidence intervals (CI) were used. Trial sequential analysis (TSA) was used for analysis to assess the risk of random error due to sparse data and to multiple updating of accumulating data. MAIN RESULTS Eighty-six trials (10,716 participants) were included. Ten trials (4,950 participants) were considered to be low risk of bias. Pooled analysis of all trials showed that off-pump CABG increased all-cause mortality compared with on-pump CABG (189/5,180 (3.7%) versus 160/5144 (3.1%); RR 1.24, 95% CI 1.01 to 1.53; P =.04). In the trials at low risk of bias the effect was more pronounced (154/2,485 (6.2%) versus 113/2,465 (4.6%), RR 1.35,95% CI 1.07 to 1.70; P =.01). TSA showed that the risk of random error on the result was unlikely. Off-pump CABG resulted in fewer distal anastomoses (MD -0.28; 95% CI -0.40 to -0.16, P <.00001). No significant differences in myocardial infarction, stroke, renal insufficiency, or coronary re-intervention were observed. Off-pump CABG reduced post-operative atrial fibrillation compared with on-pump CABG, however, in trials at low risk of bias, the estimated effect was not significantly different. AUTHORS' CONCLUSIONS Our systematic review did not demonstrate any significant benefit of off-pump compared with on-pump CABG regarding mortality, stroke, or myocardial infarction. In contrast, we observed better long-term survival in the group of patients undergoing on-pump CABG with the use of cardiopulmonary bypass and cardioplegic arrest. Based on the current evidence, on-pump CABG should continue to be the standard surgical treatment. However, off-pump CABG may be acceptable when there are contraindications for cannulation of the aorta and cardiopulmonary bypass. Further randomised clinical trials should address the optimal treatment in such patients.

Abstract
BACKGROUND AND AIM OF THE STUDY This study aimed to compare the early outcomes of off-pump and on-pump myocardial revascularization in patients with stenosis in the left anterior descending artery (alone or with diagonal artery disease). METHODS We retrospectively reviewed the medical records of 300 patients: 150 who underwent on-pump coronary artery bypass and 150 who underwent off-pump coronary artery bypass grafting. There were no significant differences between the 2 groups with respect to medical data and operative findings. On-pump and off-pump groups were compared in terms of mortality and morbidity within 30 days of the operation. RESULTS Hospital mortality was 3.3% (5 patients) in the on-pump group and 2.6% (4 patients) in the off-pump group. Five patients (3.3%) in the on-pump group experienced myocardial infarction; 3 died of cardiogenic shock. Four patients (2.6%) in the off-pump group experienced myocardial infarction, and 2 of these patients died. Two patients (1.3%) in the on-pump group and 2 patients (1.3%) in the off-pump group experienced stroke; 1 patient in each group died. One patient (0.6%) in the on-pump group had mediastinitis and died of sepsis. CONCLUSIONS Among low-risk patients (defined according to EuroSCORE criteria) who underwent left anterior descending coronary artery bypass, the results obtained with the on-pump and off-pump methods showed no significant differences with respect to morbidity or mortality.

Abstract
We evaluated the influence of methylprednisolone in cardiopulmonary bypass fluid on scavenger receptor for hemoglobin CD163 molecule expression on monocytes of patients who underwent elective coronary artery bypass grafting with cardiopulmonary bypass with either exposure to methylprednisolone present in the cardiopulmonary bypass fluid (20 patients), or without methylprednisolone in the cardiopulmonary bypass fluid (22 patients) and operated on without cardiopulmonary bypass (42 patients). The dynamics of CD163 expression was also followed in patients operated on without cardiopulmonary bypass. This study was a retrospective analysis of a comparison of two studies. The expression of CD163 was determined quantitatively by standardized flow cytometry technique. The similarities in the dynamics of CD163 monocyte expression, comparing the patients operated on with or without cardiopulmonary bypass, were found. Compared to the preoperative level, CD163 monocyte expression was significantly elevated on the 1(st) postoperative day. Monocyte CD163 expression on the 1(st) postoperative day was evidently similar in both groups of patients operated without cardiopulmonary bypass (median value of mean fluorescence intensity (MFI) 18,896; interquartile range from 27,538 to 57,711; median value of MFI 18,863; interquartile range from 16,514 to 26,559; n.s.), suggesting high reproducibility of our flow cytometric method; the monocyte CD163 expression was significantly higher (median value of MFI 37,902; interquartile range from 27,538 to 57,711) on the 1(st) postoperative day in patients exposed to methylprednisolone compared to patients without this exposure (median value of MFI 20,995; interquartile range from 16,321 to 29,623) (p<0.001). We concluded that the expression of hemoglobin scavenger receptor CD163 on monocytes of cardiac surgical patients is induced by methylprednisolone present in cardiopulmonary bypass fluid.

Abstract
BACKGROUND The survival difference between off-pump and on-pump coronary artery bypass graft surgery for follow-up longer than 5 years is not well-understood. The objective of this study is to examine the difference in 7-year mortality after these 2 procedures. METHODS AND RESULTS The state of New York's Cardiac Surgery Reporting System was used to identify the 2640 off-pump and 5940 on-pump patients discharged from July through December 2000. The National Death Index was used to ascertain patients' vital statuses through 2007. A logistic regression model was fit to predict the probability of receiving an off-pump procedure using baseline patient characteristics. Off-pump and on-pump patients were matched with a 1:1 ratio based on the probability of receiving an off-pump procedure. Kaplan-Meier survival curves for the 2 procedures were compared using the propensity-matched data, and the hazard ratio for death for off-pump in comparison with on-pump procedures was obtained. In subgroup analyses, the significance of interactions between type of surgery and baseline risk factors was tested. In this study, 2631 pairs of off-pump and on-pump patients were propensity matched. The 7-year Kaplan-Meier survival rates were 71.2% and 73.4% (P=0.07) for off-pump and on-pump surgery, respectively. The hazard ratio for death (off-pump versus on-pump) was 1.10 (95% confidence interval: 0.99 to 1.21, P=0.07). No statistical significance was detected for the interaction terms between the type of surgery and a number of different baseline risk factors. CONCLUSIONS The difference in long-term mortality between on-pump and off-pump coronary artery bypass graft surgery is not statistically significant.
