Bilateral congenital coronary artery-pulmonary artery fistulas. Report of two cases and review of the literature.

Congenital coronary arteriovenous fistulas involving both coronary arteries are rare. Two cases are presented where the origin and termination of the fistulous communication have been visualized by selective coronary angiography. Both patients underwent successful surgical treatment. Our experience and the clinical features of 12 previously reported cases treated surgically are discussed.
