It was reported that the procedure was performed to treat a mildly calcified, mildly tortuous left anterior descending artery that was 60-70% stenosed.After pre-dilatation, a non-abbott 3.0x33 stent failed to cross the lesion.It was then attempted with a 3.0x28mm everlink stent delivery system (sds) but failed due to the anatomy and the proximal shaft separated.The separated sds was withdrawn with the guiding catheter as a single unit.Two new non-abbott stents (2.5x29mm and 4.0x18mm) were implanted to successfully complete the procedure.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.
