Early clinical and angiographic outcomes after robotic-assisted coronary artery bypass surgery

Objective: Robotic-assisted coronary artery bypass grafting has emerged as an alternative to traditional coronary artery bypass grafting or percutaneous intervention for patients with coronary artery disease. However, the safety and efficacy of this minimally invasive procedure have not been established in large series.Methods: From October 2009 to September 2012, 307 consecutive robotic-assisted coronary artery bypass grafting procedures were performed at a single US institution by 2 surgeons. Isolated, off-pump, left internal thoracic artery to left anterior descending coronary artery grafting was planned via a 3- to 4-cm non–rib-spreading minithoracotomy after robotic left internal thoracic artery harvest in all patients. Hybrid coronary revascularization was planned in 159 patients (51.8%). Of the 199 angiograms (64.8%) performed before discharge, 63 were performed as completion angiograms in a hybrid suite immediately after left internal thoracic artery–left anterior descending artery grafting.Results: Thirty-day mortality occurred in 4 patients (1.3%), conversion to sternotomy occurred in 16 patients (5.2%), postoperative myocardial infarction occurred in 5 patients (1.6%), and reexploration for bleeding occurred in 7 patients (2.3%). There was 1 (0.3%) postoperative stroke. For the 199 patients with follow-up angiography before discharge, the left internal thoracic artery was confirmed to be patent (
