Abstract OBJECTIVES To compare different configurations of the bilateral internal thoracic arteries for the left coronary system and examine early and late outcomes, including mid-term graft patency. METHODS We reviewed 877 patients who underwent primary isolated coronary artery bypass grafting using in situ bilateral internal thoracic arteries [in situ right internal thoracic artery (RITA)-to-left anterior descending artery (LAD) grafting, n = 683; in situ left internal thoracic artery (LITA)-to-LAD grafting, n = 194]. We compared mid-term patency between the grafts. Propensity score matching was performed to investigate early and long-term outcomes. RESULTS The 2-year patency rate for RITA-to-LAD and LITA-to-LAD grafts were similar. Multivariate analysis revealed that RITA-to-non-LAD anastomosis (P = 0.029), postoperative length of stay (P = 0.003) and chronic obstructive pulmonary disease (P = 0.005) were associated with graft failure. After statistical adjustment, 176 propensity-matched pairs were available for comparison. RITA-to-LAD grafting enabled a more distal anastomosis. Kaplan–Meier analysis revealed that the incidences of death, repeat revascularization and myocardial infarction were significantly higher in the LITA-to-LAD group among both the unmatched and matched samples (P = 0.045 and 0.029, respectively). CONCLUSIONS The mid-term patency and outcomes of RITA-to-LAD grafting are good and reduces future cardiac event, in contrast to LITA-to-LAD grafting.

Background Clinical outcomes (as national clinical data) of isolated coronary artery bypass grafting have been successively reported, based on data registered in the Japan Cardiovascular Surgery Database, since 2013. In this study, we analysed the clinical results of isolated coronary artery bypass from 2017 to 2018 as a biannual report. Methods Data from the Japan Cardiovascular Surgery Database on isolated coronary artery bypass performed in 2017 and 2018 were reviewed for preoperative characteristics, postoperative outcomes, and choice of graft material for the left anterior descending artery. Results Isolated off-pump coronary artery bypass was performed in 54.6% ( n = 14,684) of all coronary artery bypass cases ( n = 26,913), and graft material for the left anterior descending artery was the left internal thoracic artery in 76.4% of cases and the right internal thoracic artery in 19.0% of cases. Operative mortality was 1.5% in elective cases (on-pump coronary artery bypass 1.9% and off-pump 1.2%, p < 0.001), 7.4% in emergency cases (on-pump 10.2% and off-pump 4.3%, p < 0.001), and 2.5% overall. Postoperative morbidity was generally lower in off-pump coronary artery bypass. The severity of surgery with expected mortality, evaluated using JapanSCORE II, is increasing every year. Conclusions Our findings suggest that short-term operative results for isolated coronary artery bypass are stable, and operative candidates are shifting to higher-risk patients.
