It was reported that dissection and patient death occurred.A 10mmx3.25mm wolverine coronary cutting balloon was selected for use.During the procedure, after ablation was performed in the left main trunk and proximal left anterior descending artery (lad), dilation was performed with this device.Then, while dilating the lesion with a non-boston scientific drug-coated balloon (dcb), the blood flow in circumflex (cx) decreased.The device was removed normally.The percutaneous cardiopulmonary support (pcps) was then inserted, and the procedure was completed.The patient died of acute heart failure after the procedure.According to the physician, there is no relationship between the decrease in cx flow and rota because the site of use is different.The physician thought that the dissection might have occurred when wolverine or dcb was used and reviewed the ivus records, but could not find the cause.
