It was reported surgical intervention was required to remove an entrapped burr.The target lesion was located in the distal right coronary artery (rca) in which a stent had been previously implanted.A 1.50mm rotapro was selected for use in an atherectomy procedure.During the procedure, the burr became entrapped in the lesion in the stented area of the rca.A 7fr guide catheter and 7fr guidezilla guide extension catheter were used to remove the burr.However, the guidezilla could not be advanced to the burr.A second guide catheter was inserted through the opposite (left) groin and attempted to wire along the entrapped burr without success.The rotapro burr hub was then cut off, and the burr fluid sheath and guidezilla were removed.A 2mm non-bsc snare catheter was placed but the snare shaft snapped when pulling on the burr.A second snare was used but could not remove the burr.The patient remained stable during all intervention attempts, and then the patient was sent to the operating room for successful coronary bypass grafting.The patient is currently stable.
