Consideration of the Necessity of Prophylactic Bypass Grafting for Anomalous Origin of the Right Coronary Artery—Based on a Case with Concomitant Left Main Trunk Disease Resuscitated from Cardiopulmonary Arrest

Abstract: Anomalous origin of the right coronary artery is a rare congenital anomaly, but is associated with sudden death. Originating from the opposite sinus of Valsalva, an interarterial course and an intramural course are especially considered as the risk factor for fatal cardiac events. Surgical indication remains controversial because many patients are asymptomatic. A 52-year-old man with anomalous origin of the right coronary artery with an interarterial course concomitant with the left main trunk disease was resuscitated from cardiopulmonary arrest. It was likely to be attributed to the left main trunk disease, but anatomical structure of the right coronary artery suggests its possible involvement. Prophylactic bypass grafting for the right coronary artery was performed using saphenous vein graft without ligating native vessel to prevent future cardiac events, as well as revascularization of the left main trunk disease. All grafts were patent in one-year follow-up coronary angiography. Any cardiac event has not occurred.
