Objective To investigate the safety and effectiveness of the multi-artery graf tstrategy for coronary bypass (MICS-CABG) with small incision in the left chest, and to provide experience for the promotion of this technique.Methods The clinical data of 64 patients with MICS-CABG in Department of Cardiac Surgery of Peking University Third Hospital from December 2015 to November 2019 were retrospectively analyzed. There were 54 males and 10 females, aged 36-77 (61.1±8.7) years. The left lateral thoracic incision (5-8 cm) was made through the 5th intercostal incision, and the operation was performed under off-pump CABG. With the help of the chest wall suspension device and the heart fixator, the proximal anastomosis of the ascending aorta, anastomosis of the target vessels of the  left anterior descending (LAD), left circumflex (LCX) and right coronary artery (RCA) systems were completed. The number of grafts was 2-4 (2.3±0.5) including 2 grafts in 45 patients, 3 grafts in 17 patients and 4 grafts in 2 patients. Three patients were treated with percutaneous intervention (PCI) hybridization and 62 patients were treated with total artery bypass graft. Coronary angiography was performed within 7 days after the operation to evaluate the graft patency rate. The incidence of major adverse cardiac and cerebrovascular events (MACCE) was recorded in the follow-up. The MACCE rate was calculated by Kaplan-Meier method.Results None of the patients was transferred to thoracotomy and no intra-aortic balloon counterpulsation (IABP) or extracorporeal membrane oxygenation (ECMO) was used during the operation. Incision infection was in 1 patient and reoperation in 2 patients (all were postoperative hemorrhage). Within 30 days after surgery, MACCE occurred in 1 patient, including 1 patient of non-fatal myocardial infarction. The overall patency rate of angiography bypass was 96.2%, and the patency rate of anterior descending branch bypass was 98.2%. Follow-up was performed from 12 to 60 months (median follow-up time was 28 months). The loss rate was 7.8% (5/64). The incidence of MACCE was 84.9% (95%CI 79.5%-90.3%).Conclusion The MICS-CABG can achieve completed re-vascularization and totally artery-CABG and the short-term and medium-term clinical results of the operation are good.
