Event Description
|
It was reported that blade lifted and stuck in lesion occurred.The patient presented with angina.The 90% stenosed target lesion was located in the mildly tortuous and severely calcified posterior descending branch.A 10mmx2.00mm wolverine coronary cutting balloon was selected for use.During the procedure, the wolverine was repeatedly inflated in the lesion and strong resistance was felt when it was pulled out from the blood vessel.It seems that the device was stuck in the lesion, but the guiding position was adjusted to improve the alignment and the catheter was recovered with nothing remaining inside the patient.Upon checking the recovered balloon, it was noted that the blade was lifted.The procedure was completed with a different device.There was no patient injury.
