It was reported that shaft separation occurred.The totally occluded target lesion was located in the severely calcified mid right coronary artery (rca).A stingray lp catheter was selected for use.During procedure, the stingray catheter was advanced through the 7f non-bsc guide catheter into the subintimal mid rca, however the stingray balloon was unable to cross the lesion.As the catheter was being pulled back from the patient¿s body, it was noted that the stingray got caught on the distal edge of the guide catheter and separated from the shaft at the proximal end of the balloon.The lesion was then dilated and the procedure was completed with another stingray catheter.No patient complications were reported and patient¿s status was fine.
