A case of multiple coronary microfistulas to the left ventricle and apical myocardial hypertrophy coexisting with stable angina.

A coronary artery fistula consists of a communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common congenital anomaly that can affect coronary perfusion. However, coronary fistulas to one of the cardiac chambers and coexisting apical myocardial hypertophy are infrequent anomalies, and usually are found unexpectedly. Herein, we report a case in which all three major coronary arteries emptied into the left ventricle with apical hypertrophy, through multiple microfistulas.
