It was reported that the procedure was to treat a 90% stenosed de novo perforation in the left anterior descending (lad) artery with heavy calcification and mild tortuosity.The 3.50x19mm graftmaster (gm) stent delivery system (sds) was attempted to be advanced to the target lesion; however, failed to advance due to the anatomy.Therefore, the sds was removed from the anatomy and the stent was noted to be dislodged from delivery system.A snare device was used to remove the dislodged stent from the anatomy.There was no adverse patient sequela and no clinically significant delay reported in the procedure.Another same size gm was used successfully in the procedure.No additional information was provided.
