Successful percutaneous closure of a coronary artery fistula with a detachable balloon

Precutaneous transcatheter closure technique of a coronary artery fistula with a detachable balloon was performed for a 14 year old male student. Complete closure of the fistula without any complications was confirmed by angiography after the procedure. When the patient underwent a second angiography 6 months after the closure, it was confirmed that the position of the balloon had not changed, that the interruption of the flow of the fistula had been maintained and that the diameter of the left coronary artery and the fistula were reduced. Percutaneous closure technique using a detachable balloon may become the primary treatment for a coronary artery fistula in place of surgical ligation.
