title: Transcatheter occlusion of a large coronary arterial fistula with new detachable platinum microcoils.
abstract: We report a 17 year old boy with a large fistula from the right coronary artery to the right ventricle. The fistula consisted of two major branches. The smaller branch could be embolised with three detachable platinum microcoils without problems. The high flow of blood in the larger branch, however, prevented conventional occlusion using coils. Interventional occlusion of this branch was achieved in a second attempt. Following creation of an arterio-venous wire-loop, we advanced a balloon catheter into the distal end of the fistula. Under temporary occlusion of the fistula, complete closure was achieved by delivery of 7 detachable platinum microcoils. Thus, even large coronary arterial fistulas can be closed safely with these new platinum detachable microcoils. The procedure, however, requires temporary control of the flow of blood by balloon occlusion.
