Catheter Closure of Coronary Artery Fistula



Coronary artery fistula (CAF) is a direct communication between one or more coronary arteries and a cardiac chamber or a great vessel bypassing the capillary network. The true incidence of CAF is unknown since most are silent and therefore undetected. The incidence of CAF is 0.3–0.8% in patients undergoing diagnostic cardiac catheterization. Most fistulae arise from the right coronary artery (RCA), followed by the left anterior descending (LAD) and the left circumflex (LCx) arteries in that order. Rarely, fistulae may arise from more than one coronary artery. Over 90% of the CAFs drain in the right heart chambers.
