Echocardiogram showed dilated tortuous left subclavian vein, persistent left superior vena cava, and a possible coronary arterial fistula. Coronary angiogram showed large aneurysmal left circumflex artery (LCX) with large LCX to coronary sinus fistula. Coronary artery fistula was closed with transcatheter techniques by using Amplatzer duct occluder. There was small and clinically insignificant flow observe after the procedure. ( A ) Right anterior oblique (RAO) caudal view showed large aneurysmal dilatation of LCX (black arrow) and large LCX to coronary sinus fistula (white arrow).
