Event Description

It was reported that the device was difficult to remove.Vascular access was obtained via transforaminal injection.The 90% stenosed target lesion area was located in a severely tortuous and severely calcified mid left anterior descending artery.A 10mmx2.00mm wolverine coronary cutting balloon was selected for use in a percutaneous coronary intervention.Ablation was performed by rotapro but the flow was slow so the burr was down sized to 1.25mm.After dilatation, ivus was performed to check the lesion.Remaining part was noted so dilatation was continued by the wolverine.Upon removal, the device was difficult to remove.Inflation and deflation was repeated several times and the device was removed.The device was inspected and the blade was deformed.The procedure was completed with another of the same device.No complications reported and the patient is stable.
