Transcatheter embolization of recanalized coronary artery fistula with Nit-Occlud device.

Congenital coronary artery fistula is a rare anomaly with varying symptomatology that may be addressed with surgical or interventional closure. Recanalization after complete occlusion of a coronary artery fistula has only been reported after surgical but not after interventional closure. We present a case of coronary artery fistula recanalization after angiographically documented complete transcatheter occlusion with Gianturco coils. The fistula was successfully managed by transcatheter implantation of a Nit-Occlud system, originally designed for interventional closure of patent ductus arteriosus.
