Case report: Transcatheter closure of a giant and tortuous right coronary artery to right ventricle fistula in an infant.

ABSTRACT

Congenital coronary artery fistulas (CAFs) are an uncommon congenital anomaly. While most patients are asymptomatic, life-threatening events including sudden death, myocardial ischemia, heart failure, infective endocarditis, and rupture of aneurysm may occur. Surgical ligation was once the standard choice of management of CAFs in the past. However, transcatheter closure of CAFs has become an emerging alternative to surgery in patients with suitable anatomy. We reported a 7-month-old infant with a giant and tortuous CAF that originated from the distal right coronary artery and drained into the right ventricle, and was successfully treated by transcatheter closure with an Amplatzer ductus occluder.
