The current study reviews clinical feasibility experiences evaluating safety and efficacy of using robotic assistance to create a left internal mammary artery to left anterior descending artery (LIMA-to-LAD) anastomosis. Between August and November 1999, 9 patients (aged 54-73 years) underwent robotically assisted endoscopic coronary artery bypass grafting (E-CABG) after institutional review board approval and informed consent were obtained. The robotics were transthoracically introduced in the

Each anastomosis was performed robotically, without necessity for intraoperative intervention with traditional techniques. Robotic anastomosis times averaged 29.05 minutes. The robotic system added on average 41.28 minutes to the procedure. LIMA flows prior to anastomoses measured from 11.2 to 29.2 mL/min. LIMA flow measurements following anastomoses averaged 42.07 mL/min. There were no deaths or perioperative myocardial infarctions. Although E-CABG is an exhaustive and technically demanding procedure, it is feasible for a computerenhanced robotic telemanipulation system to safely and effectively provide substantial assistance to the surgeon completing a thoracoscopic coronary anastomosis.
