Closure of an acquired aortocoronary venous fistula after coronary artery bypass grafting causing heart failure and stable angina: A case report.

Iatrogenic aortocoronary venous fistula arising from anastomosing an aortocoronary graft to a cardiac vein is a rare a complication following coronary artery bypass grafting. A 75-year-old male patient was admitted with recurrent angina accompanied by congestive heart failure six years after surgery. He was diagnosed with an acquired saphenous vein graft-to- cardiac vein fistula. Based on the estimation of risks versus benefits, the heart team decided to perform percutaneous closure with a vascular occlusion device. Subsequently, complaints and echocardiographic findings of the patient resolved.
