Retrograde coaxial transarterial coil occlusion of congenital coronary arteriovenous fistula in a 22-month-old boy and a brief literature review.

摘要

Congenital coronary arteriovenous fistula (CAVF) to the right cardiac chamber or vessel is a rare anomaly that may cause severe morbidity and mortality . Surgical repair by means of either epicardial closure of the fistula or cardiopulmonary bypass and cardiotomy to close the site of drainage has been advised by many authors [2-4]. Recently, transcatheter coil occlusion has been advocated as a treatment of choice for congenital CAVF for its excellent results [5-14]. We report here successful retrograde coaxial transarterial coil occlusion of a fistula between the left anterior descending coronary artery and the right atrium (RA) in a 22-month-old boy. We make a brief review from the English literature of 26 reported pediatric patients with congenital CAVF treated by transcatheter coil occlusion.
