Congenital left circumflex artery fistula drainage into left ventricle.

Congenital communication between left coronary artery to left ventricle is a rare anomaly. A 52-year-old male patient visited our institution complaining of paroxysmal palpitation and echocardiography revealed a large fistula draining into the left ventricle. Coronary angiography and computed tomography (CT) scanning confirmed the fistula located between the left circumflex coronary artery (LCX) and left ventricle (LV). A simple fistula ligation was performed, and postoperative three-dimensional coronary CT scanning confirmed the patient got a complete cure.
