Abstract


Coronary artery fistula (CAF) is a rare complication following coronary artery bypass grafting (CABG). True incidence is unknown, as at least 50% are asymptomatic. CAF can be either congenital or acquired. Congenital CAF is either an isolated finding or seen with other congenital cardiac anomalies or structural heart defects. Acquired CAF is seen in relation with trauma, infection, or iatrogenic injury. We report a rare case of a 58-year-old man with iatrogenic aorto-right atrial fistula following inadvertent saphenous vein grafting (SVG) implantation to a right coronary vein with persistent angina following CABG and resolution of symptoms following successful obliteration of large, hemodynamically significant, fistulae by coil embolization when medical management failed.
