Anomalous Aortic Origin of the Left Coronary Artery From the Right Coronary Sinus: Diagnosis and Surgical Repair of Intramural Retrovalvular Coronary Artery.

Abstract

Anomalous aortic origin of the left coronary artery from the right coronary sinus is a rare congenital anomaly that may cause sudden death. Direct translocation of the left coronary artery could be difficult due to its intramural course and proximity to the aortic valve. We described the surgical management of a child after sudden hemodynamic collapse and the coronary translocation technique that prevented distortion of the aortic root and allowed successful translocation of the abnormal coronary artery despite its intramural course immediately behind the aortic valve commissure.
