Sudden death related to an anomalous origin of the right coronary artery.

Nonatherosclerotic anomalies of the coronary arteries are not rare. They account for a third of sudden cardiac deaths in young patients. We report a case of resuscitated cardiac arrest due to an abnormal origin of the right coronary artery. Subsequently, coronary bypass grafting was carried out successfully. After resuscitated sudden death, there is no consensus on the diagnosis or therapeutic management of patients with abnormal coronary arteries.
