Case Reports: Transcatheter closure of congenital coronary arteriovenous fistula using detachable balloon technique

Congenital coronary arteriovenous fistula (CAF) is a direct commu- nication between coronary artery and lumen of any cardiac chamber, coronary sinus, the pulmonary artery, or the superior vena cava. Its incidence is 0.2-0.4% of all congenital cardiac defects (1). Surgical closure of CAF was initially reported in 1983 with low morbidity and mortality rates (2). Since then, successful transcatheter closure of congenital CAF in children have been reported, using coils, detachable balloons, umbrellas, polyvinyl alcohol foam, and other occluding devices (3, 4). Complications after transcatheter occlusion are rare, and avoids the need of surgery. Here we describe a case of CAF treated with a detachable balloon embolisation.
