Sudden Cardiac Death Revealed by an Anomalous Origin of the Right Coronary Artery From the Left Sinus of Valsalva

Abstract

Aberrant origin of the coronary artery from the opposite sinus of Valsalva is a rare congenital coronary anomaly associated with increased risk of myocardial ischemia and sudden death in young patients. We report a case of resuscitated sudden cardiac death in a patient with an anomalous origin of the right coronary artery, arising from the left sinus of Valsalva and coursing between the ascending aorta and the pulmonary artery. Successfully coronary arterial bypass grafting using the left radial artery was performed. Despite the risk of fatal issue, surgical management of patient with this coronary anomaly still remains controversial.
