Abstract
BACKGROUND Coronary artery bypass grafting (CABG) in the setting of an acute coronary syndrome is a high-risk procedure, and the best strategy for myocardial revascularisation remains debated. This study compares the 30-day mortality benefit of on-pump CABG (ONCAB), off-pump CABG (OPCAB), and on-pump beating heart CABG (OnBHCAB) strategies. METHODS A systematic search of three electronic databases was conducted for studies comparing ONCAB with OPCAB or OnBHCAB in patients with acute coronary syndrome (ACS). The primary outcome, 30-day mortality, was compared using a Bayesian hierarchical network meta-analysis (NMA). A random effects consistency model was applied, and direct and indirect comparisons were made to determine the relative effectiveness of each strategy on postoperative outcomes. RESULTS One randomised controlled trial and eighteen observational studies fulfilling the inclusion criteria were identified. A total of 4320, 5559, and 1962 patients underwent ONCAB, OPCAB, and OnBHCAB respectively. NMA showed that OPCAB had the highest probability of ranking as the most effective treatment in terms of 30-day mortality (odds ratio [OR], 0.50; 95% credible interval [CrI], 0.23-1.00), followed by OnBHCAB (OR, 0.62; 95% CrI, 0.20-1.57), however the 95% CrI crossed or included unity. A subgroup NMA of nine studies assessing only acute myocardial infarction (AMI) patients demonstrated a 72% reduction in likelihood of 30-day mortality after OPCAB (CrI, 0.07-0.83). No significant increase in rate of stroke, renal dysfunction or length of intensive care unit stay was found for either strategy. CONCLUSIONS Although no single best surgical revascularisation approach in ACS patients was identified, the significant mortality benefit with OPCAB seen with AMI suggests high acuity patients may benefit most from avoiding further myocardial injury associated with cardiopulmonary bypass and cardioplegic arrest.

Revascularization strategies in patients with multivessel coronary artery disease: a Bayesian network meta-analysis. Interact Cardiovasc Thorac Surg 2022; 34:947-957. [PMID: 34964468 PMCID: PMC9159431 DOI: 10.1093/icvts/ivab376] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Accepted: 12/08/2021] [Indexed: 11/15/2022] Open
Abstract
Treatment modalities for multivessel disease have rapidly evolved, yet the preferred strategy remains controversial. This meta-analysis compared outcomes after on-pump (ONCAB), off-pump coronary artery bypass grafting (OPCAB), percutaneous coronary intervention (PCI) or hybrid coronary revascularization. A comprehensive search for observational studies and randomized controlled trials published by August 2020 was performed. A Bayesian network meta-analysis was conducted for early (<30 days) and late (>12 months) outcomes. A total of 119 studies were included (n = 700 458 patients). The main analysis was confined to 31 randomized controlled trials (n = 24 932 patients). PCI was associated with lower early mortality [odds ratio (OR) 0.50, 95% confidence interval (CI) 0.31-0.79] and stroke (OR 0.22, 95% CI 0.06-0.60) rates compared with ONCAB, whereas a reduced risk of early myocardial infarction was observed with OPCAB compared with ONCAB (OR 0.53, 95% CI 0.32-0.83). Late target vessel revascularization and major adverse cardiac and cerebrovascular events were both increased with PCI compared with ONCAB, OPCAB and hybrid coronary revascularization (by 127-203% and 59-64%, respectively), and late major adverse cardiac events were increased in PCI compared with ONCAB and OPCAB (by 64% and 59%). However, PCI was associated with a significantly lower risk of late stroke compared with ONCAB (OR 0.70, 95% CI 0.52-0.89). Sensitivity analyses (i) including observational studies and (ii) limiting to studies with recent cohorts confirmed the findings of the main analysis. Surgical approaches for revascularization remain superior to PCI in patients with multivessel disease. Hybrid coronary revascularization might be viable for some patients, although more evidence from randomized controlled trials is warranted.

Abstract
Minimally invasive cardiac surgery options, which originated with off-pump coronary artery bypass grafting and aortic valve procedures, continue to evolve in order to address complex conditions, including those requiring mitral and tricuspid valve repair. Although these procedures are primarily indicated for high-risk patient populations, favorable patient outcomes have resulted in recommendations being expanded to include intermediate-risk groups. This article increases nursing-related knowledge of minimally invasive cardiac procedures, providing an overview of current minimally invasive cardiac surgeries and their associated risks and benefits.

Abstract
Recent years have seen an important shift in the target population for myocardial revascularization. Patients are increasingly presenting with more complex coronary artery disease (CAD), but also with multiple comorbidities and frailty. At the same time, minimally invasive strategies such as Minimally Invasive Direct Coronary Artery Bypass Grafting (MIDCAB) and Percutaneous Coronary Interventions (PCI) have been developed, which might be more appealing for this group of patients. As a result, the landscape of options for myocardial revascularization is evolving while adequate use of all resources is required to ensure optimal patient care. Heart Teams are confronted with the challenge of incorporating the new minimally invasive strategies into the decision process, yet current guidelines do not fully address this challenge. In this review, the current evidence regarding outcomes, indications, benefits, and risks of off-pump coronary artery bypass grafting (OPCAB), MIDCAB, PCI, and hybrid coronary revascularization (HCR) are discussed. Based on this evidence and on experiences from Heart Team discussions, a new decision tree is proposed that incorporates recent advances in minimally invasive revascularization strategies, thereby optimizing adequate delivery of care for each individual patient's needs. Introducing all important considerations in a logical way, this tool facilitates the decision-making process and might ensure appropriate use of resources and optimal care for individual patients.

Abstract
OBJECTIVE The mortality of coronary artery bypass graft surgery (CABG) in Asian patients predicted by Western population-based risk models is not ideal. We aimed to develop a risk scoring system based on a multiracial Asian patient population to predict early-stage mortality. METHODS A total of 2495 patients who underwent isolated CABG in Singapore from 2009 to 2015 were included to develop a regional scoring system: the regional Asian System for Cardiac Operative Risk Evaluation in CABG (ASCORE-C). Predictors were identified via a stepwise multiple logistic regression to construct models for 30-day, 90-day, and 1-year cumulative mortality prediction. The optimal cut-offs of ASCORE-C risk strata were determined by the multiway χ2 and Interaction Detection decision tree. The performance of ASCORE-C was compared with European System for Cardiac Operative Risk Evaluation score (EuroSCORE) II and Society of Thoracic Surgeons (STS) score by observed/estimated mortality ratio. RESULTS The observed postoperative 30-day, 90-day, and 1-year cumulative mortality following isolated CABG were 2.6%, 3.3%, and 4.6%, respectively. The ASCORE-C to predict these three events were constructed with age (>65 years), Malay ethnicity, congestive heart failure, abnormal heart rhythm, aortic atherosclerosis, estimated glomerular filtration rate, peripheral vascular disease, critical preoperative status, and emergency surgery. Tested by three different validation datasets, receiver operating characteristic curve of ASCORE-C model prediction performed well with the Hosmer-Lemeshow test. The ASCORE-C was found to have better predictive accuracy than EuroSCORE II and STS score in CABG mortality prediction, especially for the high-risk patients. CONCLUSION The ASCORE-C system is reliable for early-stage CABG mortality prediction in a multiracial Asian population.

Abstract
As per the findings of the SYNTAX Trial, it has been established that coronary artery bypass grafting (CABG) affords the best long-term results in patients with multivessel disease. However, it is still a point of contention whether 'off-pump' CABG (OPCAB) (on cardiopulmonary bypass) is better. Many studies appear to establish the superiority of one or the other. But there is still no well-planned multi-centre randomised controlled trial looking into all aspects of the issue that can, once and for all, put the controversy to rest. But as long as one is able to give the patient a good result, does it really matter whether the procedure is done off or on pump? This article looks at the available evidence with regard to various parameters comparing OPCAB and conventional CABG in an attempt to answer the question, if at all, it is a question!

Abstract
BACKGROUND The present study aimed to clarify the current use and outcomes of coronary artery bypass grafting (CABG) for acute coronary syndrome (ACS) based on the Japan Adult Cardiovascular Surgery Database (JACVSD) in stratified risk categories, and also to provide guidance on selection of optimal surgical strategies for ACS.Methods and Results:From January 2008 through December 2012, 7,867 isolated CABG procedures for ACS were identifiedfrom the JACVSD. Patients were stratified into 3 subgroups (<2%, 2-9.9%, ≥10%) according to preoperative risk estimations based on this database. Off- and on-pump CABG surgical outcomes were evaluated in each subgroup. Off-pump CABG (OPCAB) was the predominant surgical strategy in all subgroups. The proportion of on-pump beating CABG increased in the higher-risk groups. Although average observed mortality rates were compatible with preoperative estimated risk in all subgroups, those after OPCAB were significantly lower in the medium (2-9.9%) risk group with lower incidence of major complications. In the low (<2%) and high (≥10%) risk groups, observed mortality rates did not show statistically significant differences between off- and on-pump CABG. CONCLUSIONS In this study in Japan, OPCAB was mainly performed in patients with ACS, particularly those with estimated risk <10%, with lower mortality rates, whereas on-pump beating CABG was selected for higher-risk patients with ACS, with reasonable mortality rates.
