Background: Although burr entrapment is a rare complication of the Rotablator, it is extremely difficult to retrieve a fixedly entrapped burr without surgical procedure.

Case report: An 84-year-old male with effort angina had heavily calcified coronary trees as well as severe stenosis in the mid LCx, and moderate stenosis in the proximal LCx, and in the LMT. We planned to perform rotational atherectomy in the LCx lesions. Using 7 Fr Q-curve guiding catheter and Rotawire floppy, we began to ablate using 1.5-mm burr at 200,000 rpm. Because the burr could not pass the proximal stenosis, we exchanged the wire for Rotawire extrasupport and the burr for 1.25-mm burr, and restarted the ablation at 220,000 rpm. Although the burr could manage to pass the proximal stenosis, it had become trappe...
