Anomalous Origin of the Right Coronary Artery From the Ascending Aorta Above the Left Sinus of Valsalva

摘要

Congenital anomalous origin?of the coronary arteries is a rare but well-described cause of myocardial ischemia and sudden cardiac?death. Anomalous origin of the right coronary artery from the ascending aorta is an extraordinarily rare occurrence. We report a case of anomalous origin of the right coronary artery from the ascending aorta posteriorly above the left sinus of Valsalva found during coronary angiography for evaluation of newly diagnosed cardiomyopathy.
