Acute angular origin of left coronary artery from aorta: an unusual cause of left ventricular failure in infancy.
An unusual congenital anomaly of the left coronary artery, consisting of ostial stenosis caused by an acute angular origin of the vessel from the aorta in an infant, is presented. This anomaly resulted in progressive myocardial fibrosis and development of left ventricular congestive heart failure. The clinical state mimicked anomalous origin of the left coronary artery from the pulmonary artery.
