Device Closure of Left Circumflex Coronary Artery to Coronary Sinus Fistula

A coronary artery fistula (CAF) is defined as a direct connection between a coronary artery with right heart chambers including the right atrium, right ventricle, coronary sinus, superior vena cava, or pulmonary arteries. Elective closure of coronary artery fistula by surgery or percutaneous transcatheter technique is generally accepted in the presence of symptoms. We report a case of successful percutaneous transcatheter device closure of coronary fistula, originating from the circumflex artery and draining into the coronary sinus.
