Abstract
We report a 50‐year‐old patient with successful percutaneous closure of a large inadvertent surgical aortocoronary arteriovenous fistula (shunt flow: 1.8 L/min). With initial embolization of multiple coils, no lasting occlusion of the large fistula could be achieved. Above that, two coils migrated into the coronary venous system. Following rescue of the migrated coils through a retrograde coronary sinus approach, the fistula was occluded using a detachable balloon. Follow‐up angiograms confirmed successful closure of the fistula. In contrast to coil embolization, use of a detachable balloon seems to be the appropriate technique for percutaneous closure of such fistulas.
