Background The efficacy of intra-aortic balloon pump (IABP) has been proven in high-risk patients undergoing coronary artery bypass grafting (CABG). However, data on the timing and benefits of IABP support in diffuse coronary artery disease after CABG combined with coronary endarterectomy (CE) remain scarce. This retrospective study assessed the effect of intraoperative or postoperative IABP on 30-day outcomes of off-pump CABG+CE. Methods From January 2012 to December 2018, 546 patients undergone off-pump CABG+CE were divided into control group ( n = 437) and IABP group ( n = 109). Risk factors for 30-day outcomes were evaluated. Subgroup analysis from IABP group was conducted to identify the effect of timing IABP on 30-day outcomes. Results CE on left anterior descending branch of coronary artery (LAD) (OR = 3.079, 95% CI 1.077–8.805, P = 0.036), CE with≥2 vessels (OR = 9.123, 95% CI 3.179–26.033, P < 0.001) and length of atherosclerotic plaque ≥3 cm (OR = 16.017, 95% CI 5.941–43.183, P < 0.001) were independent risk factors for postoperative acute myocardial infarction (AMI) and 30-day mortality. Comparing with intraoperative IABP support, postoperative IABP support (OR = 3.987, 95% CI1.194–13.317, P = 0.025) was closely associated with postoperative AMI and 30-day mortality. Conclusions For patients undergone off-pump CABG and extensive CE (CE on LAD, CE ≥2 vessels and length of atherosclerotic plaque ≥3 cm), intraoperative IABP support may improve 30-day outcomes.

Double versus single source left-sided coronary revascularization using bilateral internal thoracic artery graft alone

et al. 2017

Left-sided coronary revascularization with bilateral internal thoracic artery (BITA) graft is performed usually either with an in situ (double source) or Y-graft configuration (single source). Two hundred fifty-three (mean age, 67.1 ± 9.5 years) patients underwent isolated left-sided coronary revascularization with BITA graft alone at the present authors' institution (2000-2015). Skeletonized BITA grafts were used either in an in situ (n = 199) or Y-graft configuration (n = 54). Forty pairs were identified with the propensity score-matching. Outcomes of the two groups were compared both in unmatched and matched series. Cardiopulmonary exercise testing was performed in five pairs of selected, asymptomatic matched patients having patent BITA grafts at coronary computed tomography angiography. BITA in situ patients had lower risk profiles than BITA Y-graft patients (median EuroSCORE II, 1.9 vs. 2.9%, p = 0.051). In-hospital mortality (5.6 vs. 0, p = 0.0093) and the rates of postoperative complications except deep sternal wound infection were higher in BITA Y-graft patients. However, these differences were not confirmed in matched groups. During the follow-up period (mean, 5.9 ± 4.3 years), between BITA in situ and BITA Y-graft matched patients, there were no differences in non-parametric estimates of freedom from cardiac death (p = 0.6), major adverse cardiac and cerebrovascular events (MACCEs, p = 0.65), and repeat coronary revascularization (p = 0.44). Adjusted risk estimates of MACCEs according to BITA configuration confirmed no superiority of the one configuration over the other (p ≥ 0.44). No significant differences were found at the cardiopulmonary exercise testing. Results of left-sided coronary revascularization with BITA graft alone are independent from BITA configuration, even after stress testing.
