Project description:BackgroundData on long-term outcomes in patients with diabetes receiving multiarterial grafting (MAG) versus single-artery grafting (SAG) are limited.ObjectivesThe objective of this study is to compare long-term outcomes between MAG and SAG for coronary artery bypass graft (CABG) surgery in patients with diabetes.MethodsPatients with diabetes who underwent isolated CABG surgeries between 2000 to 2016 were identified using the New Jersey mandatory state clinical registry linked with death records and hospital discharge data (last follow-up December 31, 2019). Patients who underwent CABG for single-vessel disease, with only venous conduits, patients with previous heart surgeries, or hemodynamically unstable were excluded. Patients undergoing MAG and SAG were matched by propensity score. Cox proportional hazard models were used to investigate long-term survival and competing risk analysis was used for secondary outcomes.ResultsOf 24,944 patients, 2955 underwent MAG, and 21,989 underwent SAG CABG. Patients receiving MAG were younger, predominantly men, with a lower prevalence of hypertension, peripheral vascular disease, congestive heart failure, chronic lung disease, and renal failure. MAG was associated with lower long-term mortality compared with SAG in 2882 propensity score-matched pairs (hazard ratio [HR], 0.75; 95% CI, 0.68-0.83); lower risks of repeat revascularization (subdistribution HR, 0.86; 95% CI, 0.76-0.97); and composite outcome defined as death from any cause, stroke, postoperative myocardial infarction, and/or repeat revascularization (HR, 0.76; 95% CI, 0.71-0.82). These results were confirmed in subgroup analyses of women, men, age <70 years, and age ≥70 years patients with diabetes. MAG was also associated with lower mortality compared with SAG in patients with diabetes taking insulin in the entire cohort (Video Abstract).ConclusionsPatients with diabetes benefit from receiving MAG over SAG and demonstrated improved long-term survival, and lower hazards of secondary and composite outcomes. Coordinated efforts are needed to offer MAG to patients with diabetes.

Project description:ObjectiveMultiple arterial grafting (MAG) in coronary artery bypass grafting (CABG) is associated with higher survival and freedom from major adverse cardiac and cerebrovascular events (MACCEs) in observational studies of mostly men. It is not known whether MAG is beneficial in women. Our objectives were to compare the long-term clinical outcomes of MAG versus single arterial grafting (SAG) in women undergoing CABG for multivessel disease.MethodsClinical and administrative databases for Ontario, Canada, were linked to obtain all women with angiographic evidence of left main, triple or double vessel disease undergoing isolated non-emergent primary CABG from 2008 to 2019. 1:1 propensity score matching was performed. Late mortality and MACCE (composite of stroke, myocardial infarction, repeat revascularisation and death) were compared between the matched groups with a stratified log-rank test and Cox proportional-hazards model.Results2961 and 7954 women underwent CABG with MAG and SAG, respectively, for multivessel disease. Prior to propensity-score matching, compared with SAG, those who underwent MAG were younger (66.0 vs 68.9 years) and had less comorbidities. After propensity-score matching, in 2446 well-matched pairs, there was no significant difference in 30-day mortality (1.6% vs 1.8%, p=0.43) between MAG and SAG. Over a median and maximum follow-up of 5.0 and 11.0 years, respectively, MAG was associated with greater survival (HR 0.85, 95% CI 0.75 to 0.98) and freedom from MACCE (HR 0.85, 95% CI 0.76 to 0.95).ConclusionsMAG was associated with greater survival and freedom from MACCE and should be considered for women with good life expectancy requiring CABG.

Project description:BackgroundBypass grafting for chronic total occlusions (CTOs) remains surgically challenging and controversial. Therefore, we evaluated the incidence and clinical outcomes of revascularization on CTOs undergoing coronary artery bypass grafting (CABG).MethodsAmong 828 patients who underwent isolated CABG from January 2010 to December 2018, 245 patients (29.6%) diagnosed with at least one CTO were included and retrospectively reviewed. Primary endpoints were 30-day and overall mortality. Secondary endpoint was the composite outcome of major adverse cardiac and cerebrovascular events (MACCE).ResultsWith a mean follow-up of 56.6±6.5 months in 245 patients with CTOs, 51 patients (20.8%) received incomplete revascularization (ICR) for CTO lesions. Risk factor analysis showed that ICR was associated with increased 30-day [odds ratio 8.62; 95% confidence interval (CI): 1.64-50; P=0.011] and overall mortality (hazard ratio (HR) 2.13; 95% CI: 1.07-4.21; P=0.03). ICR also increased the risk of MACCE (HR 1.98; 95% CI: 1.12-3.54; P=0.01). Freedom from overall mortality was 92.8%, 90.4%, and 86.8% in the complete revascularization group, and 86.3%, 80.0%, and 72.7% in the ICR group, at 1, 3, and 5 years, respectively (P=0.004).ConclusionsIn patients with CTOs undergoing CABG, the rate of ICR was 20.8%, and it significantly increased the risk of mortality and MACCE. Further studies in a large cohort are needed.

Project description:The development of left atrial myxoma after coronary artery bypass graft surgery is a rare entity. A 60-year-old man with previous off-pump coronary artery bypass grafting four years ago with patent coronary grafts was diagnosed with left atrial mass. The patient underwent successful resection of the same through minimally invasive right anterolateral thoracotomy. Histopathology of the atrial mass confirmed the diagnosis of atrial myxoma.

Project description:Coronary artery bypass grafting (CABG) remains the most common cardiac surgery performed today worldwide. The history of this procedure can be traced back for more than 100 years, and its development has been touched by several pioneers in the field of cardiac surgery, who have contributed with both their successes and failures. With ever increasing follow up and number of patients treated, thinking regarding optimal CABG technique evolves continually. This article reviews the history of CABG from its early experimental work to recent technological advances.

Project description:Background and purposeThe optimal operative strategy in patients with severe carotid artery disease undergoing coronary artery bypass grafting (CABG) is unknown. We sought to investigate the safety and efficacy of synchronous combined carotid endarterectomy and CABG as compared with isolated CABG.MethodsPatients with asymptomatic high-grade carotid artery stenosis ≥80% according to ECST (European Carotid Surgery Trial) ultrasound criteria (corresponding to ≥70% NASCET [North American Symptomatic Carotid Endarterectomy Trial]) who required CABG surgery were randomly assigned to synchronous carotid endarterectomy+CABG or isolated CABG. To avoid unbalanced prognostic factor distributions, randomization was stratified by center, age, sex, and modified Rankin Scale. The primary composite end point was the rate of stroke or death at 30 days.ResultsFrom 2010 to 2014, a total of 129 patients were enrolled at 17 centers in Germany and the Czech Republic. Because of withdrawal of funding after insufficient recruitment, enrolment was terminated early. At 30 days, the rate of any stroke or death in the intention-to-treat population was 12/65 (18.5%) in patients receiving synchronous carotid endarterectomy+CABG as compared with 6/62 (9.7%) in patients receiving isolated CABG (absolute risk reduction, 8.8%; 95% confidence interval, -3.2% to 20.8%; PWALD=0.12). Also for all secondary end points at 30 days and 1 year, there was no evidence for a significant treatment-group effect although patients undergoing isolated CABG tended to have better outcomes.ConclusionsAlthough our results cannot rule out a treatment-group effect because of lack of power, a superiority of the synchronous combined carotid endarterectomy+CABG approach seems unlikely. Five-year follow-up of patients is still ongoing.Clinical trial registrationURL: https://www.controlled-trials.com. Unique identifier: ISRCTN13486906.

Project description:Background Multiple percutaneous coronary interventions ( PCIs ) are considered determinant of poor outcome in patients undergoing coronary artery bypass grafting ( CABG ), but scarce data exist to substantiate this. Methods and Results Patients who underwent CABG without history of prior PCI or with PCI performed >30 days before surgery were selected for the present analysis from the prospective, multicenter E-CABG (European Multicenter Study on Coronary Artery Bypass Grafting) registry. Out of 6563 patients with data on preoperative SYNTAX (Synergy between PCI With Taxus and Cardiac Surgery) score, 1181 patients (18.0%) had undergone PCI >30 days before CABG . Of these, 11.6% underwent a single PCI , 4.4% 2 PCI s, and 2.1% ≥3 PCI s. PCI of a single main coronary vessel was performed in 11.3%, of 2 main vessels in 4.9%, and of 3 main vessels in 1.6% of patients. Multivariable analysis showed that differences in early mortality and other outcomes were not significantly different in the study cohorts. The adjusted hospital/30-day mortality rate was 1.8% in patients without history of prior PCI , 1.9% in those with a history of 1 PCI , 1.4% after 2 PCI s, and 2.5% after ≥3 PCI s (adjusted P=0.8). The adjusted hospital/30-day mortality rate was 2.0% in those who had undergone PCI of 1 main coronary vessel, 1.3% after PCI of 2 main vessels, and 3.1% after PCI of 3 main coronary vessels (adjusted P=0.6). Conclusions Multiple prior PCI s are not associated with increased risk of early adverse events in patients undergoing isolated CABG . The present results are conditional to survival after PCI and should not be viewed as a support for a policy of multiple PCI as opposed to earlier CABG .

Project description:ImportanceAlthough the long-term survival advantage of multiple arterial grafting (MAG) vs the standard use of left internal thoracic artery (LITA) supplemented by saphenous vein grafts (LITA+SVG) has been demonstrated in several observational studies, to our knowledge its safety and other long-term clinical benefits in a large, population-based cohort are unknown.ObjectiveTo compare the safety and long-term outcomes of MAG vs LITA+SVG among overall and selected subgroups of patients.Design, setting, and participantsIn this population-based observational study, we included 20 076 adult patients with triple-vessel or left-main disease who underwent primary isolated coronary artery bypass grafting (MAG, n = 5580; LITA+SVG, n = 14 496) in the province of British Columbia, Canada, from January 2000 to December 2014, with follow-up to December 2015. We performed propensity-score analyses by weighting and matching and multivariable Cox regression to minimize treatment selection bias.ExposuresMultiple arterial grafting or LITA+SVG.Main outcomes and measuresMortality, repeated revascularization, myocardial infarction, heart failure, and stroke.ResultsOf 5580 participants who underwent MAG, 586 (11%) were women and the mean (SD) age was 60 (8.7) years. Of 14 496 participants who underwent LITA+SVG, 2803 (19%) were women and the mean (SD) age was 68 (8.9) years. The median (interquartile range) follow-up time was 9.1 (5.1-12.6) years and 8.1 (4.5-11.7) years for the groups receiving MAG and LITA+SVG, respectively. Compared with LITA+SVG, MAG was associated with reduced mortality rates (hazard ratio [HR], 0.79; 95% CI, 0.72-0.87) and repeated revascularization rates (HR, 0.74; 95% CI, 0.66-0.84) in 15-year follow-up and reduced incidences of myocardial infarction (HR, 0.63; 95% CI, 0.47-0.85) and heart failure (HR, 0.79; 95% CI, 0.64-0.98) in 7-year follow-up. The long-term benefits were coherent by all 3 statistical methods and persisted among patient subgroups with diabetes, obesity, moderately impaired ejection fraction, chronic obstructive pulmonary disease, peripheral vascular disease, or renal disease. Multiple arterial grafting was not associated with increased morbidity or mortality rates at 30 days overall or within patient subgroups.Conclusions and relevanceCompared with LITA+SVG, MAG is associated with reduced mortality, repeated revascularization, myocardial infarction, and heart failure among patients with multivessel disease who are undergoing coronary artery bypass grafting without increased mortality or other adverse events at 30 days. The long-term benefits consistently observed across multiple outcomes and subgroups support the consideration of MAG for a broader spectrum of patients who are undergoing coronary artery bypass grafting in routine practice.
