It was reported that the catheter shaft break occurred.The target lesion was located in the moderately tortuous and severely calcified mid left anterior descending artery.A 10mmx3.0mm wolverine coronary cutting balloon was selected for use.During procedure, the balloon was advanced into the lesion.However, the balloon catheter shaft broke into half before inflation.The proximal part of the balloon catheter was then removed and a 2.5mmx16mm emerge balloon was used.Subsequently, the emerge balloon was inflated and trapped the remaining wolverine shaft inside the guide catheter and facilitated the removal of all the device component from the patient's body.The procedure was completed with a new guide catheter and a non-compliant balloon.No complications reported and patient was stable.
