Abstract
Background:We successfully performed totally endoscopic atrial septal defect (ASD) repair via 2 ports, and we named this procedure two-port robotic cardiac surgery (TROCS).Methods and Results:A 51-year-old woman with secundum ASD underwent robot-assisted ASD repair under ventricle fibrillation without aortic cross-clamping. Two ports were placed in the right side of the chest, and 1 port was for the robotic endoscope. Two robotic instruments were inserted through another port and crossed while preventing them from colliding.Conclusions:TROCS ASD repair using a cross-arm technique was achieved safely with good clinical results and excellent cosmetic results.
