Abstract
Fistulous communication from the coronary artery to the left ventricle (LV) is extremely rare and has received little attention in the literature. Moreover, a case of coronary artery fistula (CAF) from a diagonal branch of the left anterior descending coronary artery to the LV has been reported only once in the literature. Herein, we report a case of CAF from a diagonal branch of the left anterior descending coronary artery to the LV, along with a review of the pertinent literature regarding this disorder.
