Multiple coronary arteriovenous fistulae.

A case with multiple congenital coronary arteriovenous fistulae is reported. The right coronary artery was communicating with the right ventricle. The left coronary artery was entering directly into the pulmonary trunk and two terminal branches of the anterior descending into the left ventricle. The direct communication of the left coronary artery without interposition of an accessory artery or a circoid plexus is met for the first time.
