To evaluate the clinical effect of robot-assisted bilateral internal mammary arteries (IMAs) harvesting in the treatment of coronary heart disease with multi-vessel lesions by minimally invasive coronary artery bypass grafting. Methods: 45 patients with multivessel coronary artery disease underwent robot-assisted minimally invasive coronary artery bypass surgery via left anterolateral small incision from January 2019 to January 2020 in our hospital, of which 29 patients received totally robotic bilateral IMAs harvesting with mean age (59.2±9.5) years and 72.4% males. 20 cases (68.9%) diagnosed with double lesions and 9 cases (31.1%) with triple lesions in preoperative coronary angiography. 14 patients were performed saphenous vein harvesting for bypass grafting during the operations. Results: There were no death, perioperative stroke, myocardial infarction, reexoploration for hemostasis and other serious complications, and no patient was converted to median sternotomy. One patient with poor wound healing recovered after conservative treatment. Fifty-eight IMAs were successfully harvested in 29 patients, and the intraoperative blood flow was satisfactory. In terms of graft configurations, 10 cases had the RIMA to the left anterior descending (LAD) / LIMA to other target vessels, and 19 cases had the LIMA to LAD / RIMA- SVG composite graft to other target vessels. The average number of anastomoses was (2.27±0.3) / case, and the average graft flow was (27.3±17.6) ml/min. Conclusion: It is safe and feasible to harvest IMAs with robot for Chinese coronary heart disease patients, which is helpful to the application of minimally invasive robotic CABG in the treatment of coronary multi-vessel disease.
