title: Robotic coronary artery bypass grafting.
abstract: Robotically assisted surgery enables coronary surgery to be performed totally or partially endoscopically. Using the Da Vinci robotic technology allows minimally invasive treatments. We report on our experience with coronary artery surgery in our department: patients requiring single or double vessel surgical revascularization were eligible. The procedure was performed without cardiopulmonary bypass on a beating heart. From April 2004 to May 2008, 55 consecutive patients were enrolled in the study, and were operated on by a single surgical team. Operative outcomes included operative time, estimated blood loss, transfusions, ventilation time, intensive care unit (ICU) and hospital length of stay. Average operative time was 270 ± 101 min with an estimated blood loss of 509 ± 328 ml, a postoperative ventilation time of 6 ± 12 h, ICU stay of 52 ± 23 h, and a hospital stay of 7 ± 3 days. Nine patients (16%) were converted to open techniques, and transfusion was required in four patients (7%). Follow-up was complete for all patients up to 1 year. There was one hospital death (1.7%) and two deaths at follow-up. Coronary anastomosis was controlled in 48 patients by either angiogram or computed tomography scan, revealing occlusion or anastomotic stenoses (>50%) in six patients. Overall permeability was 92%. Major adverse events occurred in 12 patients (21%). One-year survival was 96%. Our initial experience with robotically assisted coronary surgery is promising: it avoids sternotomy and with a methodical approach we were able to implement the procedure safely and effectively in our practice, combining minimal mortality with excellent survival.
