Rare Cause of Late Recurrent Angina following Coronary Artery Bypass Grafting: Iatrogenic Aortocoronary Arteriovenous Fistula Causing Coronary Steal

Figure 3

Cardiac computed tomography (CT) angiography with 3-dimensional reconstruction showed distal left internal mammary artery (LIMA) to left anterior descending (LAD) bypass artery communicating with a cardiac vein, which is eventually communicating with the coronary sinus, suggesting a coronary arteriovenous fistula.
