Successful rescue of stuck rotablator burr entrapment using a Kiwami straight catheter

Rotational atherectomy is an indispensable modality for percutaneous coronary intervention of severely calcified lesions. An entrapped rotablator burr is a rare but life-threatening complication because retrieval is difficult. Although emergent surgical removal is a reliable option for this complication, it is invasive. There are various methods to retrieve an entrapped burr by bailout endovascular approaches. We present two cases of successful rescue of stuck rotablator burr entrapment using a Kiwami straight catheter (4 Fr, Heartrail II, Terumo, Tokyo, Japan).
