Surgical Repair of a Cause of Sudden Death

Abstract

Left coronary artery originating from the right coronary sinus is one of the most frequent causes of sudden death in young people. We present a reconstructive surgical technique for left coronary artery and main pulmonary artery in a case with anomalous origin of the left coronary artery from the right coronary sinus. A 15-year-old boy underwent unroofing of the left main coronary artery and patch arterioplasty with autologous pericardium after transection of the main pulmonary artery. The pulmonary artery was reconstructed with autologous pericardium and a piece of dacron patch in order to prevent coronary artery compression. This surgical approach resulted in successful clinical outcome.
