It was reported that the procedure was to treat a lesion in the 90% stenosed, narrow, heavily calcified mid left anterior descending coronary artery.An attempt was made to advance a 3.0x12mm nc trek balloon dilatation catheter (bdc) through the lesion for pre-dilatation; however, the bdc would not cross.It is unclear if the resistance felt was with the anatomy or other devices.When the bdc was removed, it was noted that the shaft was bent and it separated into two pieces.The distal portion of the bdc was simply removed from the patient anatomy without issue.A new unspecified bdc was used to successfully complete the procedure.No additional information was provided.
