Sudden death in a young adult with anomalous origin of the posterior circumflex artery.
Sudden unexpected death occurred in an apparently healthy young adult during physical exertion. At autopsy the posterior circumflex artery was found to emerge at an acute angle from the right aortic sinus and course behind the great vessels to reach the atrioventricular groove. There was an old superior posterolateral infarct, and fibrosis and acute hemorrhage in the region of the atrioventricular node.
