BACKGROUND: Here we explore a method of using robotics to reduce morbidity and mortality in conventional coronary surgery. METHODS: Using a robotic surgical system two surgeons completed five steps: (1) 80 synthetic suture exercises; (2) 76 left internal thoracic artery to left anterior descending (LIMA-to-LAD) on porcine hearts; (3) cadaveric port placement for assessing optimal access; (4) endoscopic stabilization in the live porcine model; and, finally (5) eight clinical LIMA-to-LADs performed robotically. RESULTS: After 70 hours training, mean dry lab times fell from 7.0 and 5.8 min to 5.7 and 5.1 min in the two surgeonstab series. Wet lab times fell from 40.1 and 28.5 min to 28.8 and 19.2 min. In the clinical series of eight patients there were no mortalities; all had uncomplicated postoperative recovery and all were angina free at 6-week follow-up. CONCLUSION: The learning curve for robotic training is short, and reproducible results can be achieved clinically, after appropriate training, resulting in real patient benefit.
