Iatrogenic coronary artery fistula in a patient with a single coronary artery.

Here, we report on a case of coronary artery fistula that developed following the repair of a double-outlet right ventricle (DORV) with infundibular pulmonary stenosis in a patient who has a single coronary artery. The major concern in this case was that of reduction of coronary blood flow from the patient's only coronary artery to the myocardium distal to the fistula.
