title: Multiple coronary arterioventricular fistulae.
abstract: A 62-year-old man who died suddenly was found at autopsy to have multiple coronary arteriosystemic fistulae involving all three major coronary arteries and both ventricles. This is the second such case reported and the first with biventricular involvement and autopsy findings. A congenital bicuspid valve was also present. Numerous small blood vessels opened onto the endocardial surface of both ventricles and there were microscopic foci of persistent embryonic spongy myocardium.
