It was reported that a balloon rupture occurred.The 90% stenosed target lesion was located in a mildly tortuous and severely calcified middle left anterior descending artery.A 10mmx4.00mm wolverine coronary cutting balloon was selected for use in a percutaneous coronary intervention.During the procedure, a 2.5x15 non-bsc ptca dilatation catheter was used for pre-dilatation but the catheter did not expand due to the calcification.Then, a 10x4 wolverine was used, however, it had difficulty crossing and inserting into the lesion area due to the calcification.After crossing the lesion, the balloon ruptured when dilatation was performed at 12 atm.All the components were completely removed from the patient's body.The procedure ended was completed with the orginal device as desired treatment was achieved.No complications reported and the patient was stable post procedure.
