We summarized our experience with total arterial off-pump coronary artery bypass grafting （OPCAB） and assessed the early clinical results, surgical complications, and follow-up. Methods： From January 2007 to May 2017,508 coronary artery disease patients undergoing total arterial OPCAB were enrolled. Clinical features, approaches, outcomes of surgical treatments, and follow-up data of these patients were studied retrospectively. A total of 122 patients underwent single left internal mammary artery （IMA）-left anterior descending artery grafts, whereas the other 386 patients underwent multiple vessel grafts. Results： The average distal anastomosis was 2.34 ± 0.97 （range： 1-4）. All the patients were discharged from hospital except one died. A total of 457 （90.32%） patients were followed up. In the 4-, 7-, and 10-year follow-up groups, the rate of death from any cause was 1.19%, 6.47%, and 10.67%; rate of cardiac death was 0.60%, 2.88%, and 3.33%; rate of repeat revascularization was 0.00%, 3.60%. and 8.67%; rate ofischemic symptoms was 1.79%, 7.91%, and 11.33%; and incidence of stroke was 2.38%, 4.32%, and 6.67%, respectively. Poor medication adherence was observed in 9.38% of the follow-up population. Conclusions： Total arterial OPCAB with bilateral IMA, radial artery, and right gastroepiploic artery grafting yielded satisfactory early and midterm outcomes in this patient group, without a significant increase in early mortality or morbidity. Moreover, the long-term outcomes are also positive.展开更多
