Abstract
OBJECTIVES: The results of coronary artery bypass graft (CABG) surgery with total arterial revascularisation (TA-CABG) in elderly patients, who may have insufficient vein graft material for conventional CABG (CO-CABG), have not been fully established. We therefore sought to compare the short- and long-term outcomes of patients >70 years old undergoing CO-CABG and TA-CABG. METHODS: We performed a retrospective observational study analyzing all consecutive adult patients aged >70 years undergoing first-time CABG over the 15-year period from 2004 to 2020 under a single surgeon. Primary outcomes of interest were in-hospital mortality, long-term mortality, and re-intervention rate. Secondary outcomes of interest included operative durations and the incidence of peri-operative complications. RESULTS: There were 46 patients (age 76 ± 3 SD) in the TA-CABG group and 145 patients (age 76 ± 4 SD) in the CO-CABG group. Cardio-pulmonary bypass and cross-clamp durations were comparable between groups (p = .11 and p = .23, respectively). Stroke occurred in 1.0% undergoing CO-CABG compared to 0% in the TA-CABG group (p = .42). Hospital mortality was 3.0% with CO-CABG (EuroSCORE; mean [SD] 6.81 (5.81)) and 2.0% with TA-CABG (EuroSCORE; mean [SD] 6.38 (6.57)) (p = .93). On long-term follow-up, myocardial infarction occurred in 10.0% of CO-CABG patients compared to 4.0% of TA-CABG patients (p = .25). Re-intervention rates were 7% following CO-CABG, and 2% after TA-CABG (p = .23). There was no significant difference in long-term mortality between patients undergoing CO-CABG and TA-CABG (47% vs. 57%, p = .27). Long-term survival was comparable between grafting techniques (p = .27). CONCLUSIONS: There were no significant differences in major adverse cardiac and cerebrovascular events, re-intervention rate, hospital or long-term mortality between CO-CABG and TA-CABG. TA-CABG represents a safe and feasible alternative to CO-CABG in elderly patients offering good long-term outcomes.
