Hybrid coronary revascularization: Midterm outcomes of robotic multivessel bypass and percutaneous interventions

Objective: The purpose of this study was to investigate the outcomes of patients undergoing advanced hybrid coronary revascularization, defined as robotic beating-heart multivessel totally endoscopic coronary artery bypass combined with percutaneous coronary intervention. Methods: This is a retrospective study. Among 308 consecutive patients who underwent totally endoscopic coronary artery bypass, 57 who underwent advanced hybrid coronary revascularization (mean age, 65.6 years) from July 2013 to September 2017 were included. Midterm survival and freedom from major adverse cardiac events, including death, myocardial infarction, and repeat revascularization, were analyzed. Results: Multivessel totally endoscopic coronary artery bypass was successfully performed without conversion to thoracotomy. Bilateral internal thoracic artery grafting was used in 50 patients (87.7%). The mean operative time was 318.4 +/- 51.0 minutes. The mean length of hospital stay was 3.0 +/- 1.3 days. There was no 30-day mortality. Percutaneous coronary intervention was planned after totally endoscopic coronary artery bypass in 51 patients (89.4%). The target lesions were the right coronary artery only in 38 patients, the left circumflex artery only in 4 patients, and multiple lesions in 13 patients. Eventually, 2 patients did not receive percutaneous coronary intervention. Percutaneous coronary intervention attempt was unsuccessful in 8 lesions. Patency of the left/right internal thoracic artery was 95.2%(60/63) and 95.7%(45/47), respectively. Graft patency was 95.2%(40/42) in the left circumflex artery and 93.3%(14/15) in the diagonal branch. Three-year survival was 92.8%, and 3-year freedom from major adverse cardiac events was 80.2%. Conclusions: Advanced hybrid coronary revascularization is a safe and less-invasive approach with short hospital stay and good midterm outcomes.
