BACKGROUND Total arterial revascularization is associated with increased patency and long-term efficacy and decreased perioperative morbidity and mortality and incidence of cardiac-related events and sternal wound infection compared with conventional coronary artery bypass surgery(CABG),in which the left internal mammary artery(LIMA)is typically grafted to the left anterior descending artery with additional saphenous vein grafts often used.This study determined whether these favorable clinical results could be realized at the authors’institute.AIM To summarize the early efficacy and clinical experience of individualized total arterial coronary artery bypass grafting surgery.METHODS CABG was performed on 35 patients with non-single-vessel coronary artery disease by adopting total arterial grafts at Fourth Affiliated Hospital of Harbin Medical University between April 2016 and December 2019.LIMA was used in 35 patients,radial artery(RA)was used in 35 patients,and right gastroepiploic artery(RGEA)was used in 9 patients.Perioperative complications were observed,short-term graft patency rate was followed-up,and quality of life was assessed.RESULTS All patients underwent off-pump coronary artery bypass and the surgeries were successful.All of them were discharged without any complications or deaths.During the follow-up,it was found that patients’angina symptoms were relieved and New York Heart Association classification for cardiac function was class I to class II.A total of 90 vessels were grafted with no occlusion for internal mammary artery,three occlusions for RA,and one occlusion for RGEA.CONCLUSION The individualized total arterial strategy based on the vessels targeting individual anatomic characteristics can achieve complete revascularization with satisfactory short-term grafting patency rate.
