Anomalous Right Coronary Artery Arising from the Left Sinus of Valsalva in a Young Athlete.

Cardiac events associated with congenital coronary abnormalities are rare but potentially life-threatening in a young population. Most of these patients are not diagnosed before their initial cardiac event. Amongst such coronary artery anomalies, sudden death is frequently seen in an anomalous origination of a coronary artery from the opposite sinus. We herein present the case of a patient who presented with sudden cardiac arrest associated with an anomalous right coronary artery originating from the left sinus of Valsalva. Surgical treatment was selected because there was evidence of reversible ischemia based on the findings of a stress test.
