A patient with very diseased vessels was undergoing a percutaneous coronary intervention of the right coronary artery to reduce a lesion.When the radiologist maneuvered the burr catheter in place and began to drill, it felt like drilling into cement.The catheter bent over itself because the lesion was so dense.As the device twisted, the burr broke at the tip and embolized.The catheter was removed from the patient but the burr tip remained in the patient.There was no autopsy performed so it is unclear specifically how the burr tip contributed to the death of this patient.
