Bicoronary-pulmonary fistulae with coexistent mitral valve prolapse: a case report and literature review of coronary-pulmonary fistula.

Bicoronary-pulmonary artery fistulae are rare congenital coronary artery fistulae. We report the case of a 57-year-old man who presented with biventricular failure and angina pectoris. At angiography the coronary arteries were normal, but bicoronary-pulmonary fistulae were noted; severe mitral regurgitation secondary to mitral valve prolapse was also present. At right heart catheterization the calculated left to right shunt was 2.1. Fistula ligation and repair of both mitral and tricuspid valves was undertaken. The literature regarding coronary-pulmonary fistula is also reviewed.
