[Complication in rotation angioplasty: removal of an intracoronary metal ring (roentgen marker) using a balloon catheter].

Successful recanalization of an occluded left anterior descending coronary artery, performed by rotational angioplasty was complicated by loosening of a metallic ring (x-ray marker) from the rotational angioplasty system, with embolization into the circumflex artery. The metallic ring was extracted successfully by using a balloon catheter.
