[Emergent operation after percutaneous transluminal coronary rotational atherectomy (ROTABLATOR)].

Emergent operations were performed in seven patients after percutaneous transluminal coronary rotational atherectomy (PTCRA). The causes of the emergent operations were coronary rupture in three patients, acute coronary occlusion in two patients, perforation of the ascending aorta in one patient and impossible weaning from IABP in one patient. IABP was used preoperatively in all patients. Coronary artery bypass grafting was performed in all patients. Ruptured sites of the coronary arteries were closed and perforated site of the ascending aorta was repaired. Two patients died due to cardiac failure but five patients were recovered. Coronary artery rupture was main complication after PTCRA. It is important to recognize the difference between the complication after PTCRA and that after conventional PTCA.
