Multiple coronary fistulas originating from all major coronary arteries.

Coronary fistulas to one of the cardiac chambers are infrequent anomalies and usually are found unexpectedly. Fistulas communicating between coronary artery and left heart chambers are extremely rare, especially those emptying into the left ventricle. We report a case in which all three major coronary arteries emptied into the left ventricle through multiple microfistulas.
