title: A rare case of Rotablator®driveshaft fracture and successful percutaneous retrieval of a trapped burr using a balloon and GuideLiner®.
abstract: A 75-year-old man with a severe calcified atheromatous plaque of the right coronary artery underwent percutaneous coronary intervention using a Rotablator®. During the procedure, the 1.5-mm burr became entrapped, and the driveshaft fractured. While various techniques for retrieving the burr were attempted, a new technique was created. The entrapped burr was sandwiched between an inflated balloon and the GuideLiner®, and a strong back-up force was obtained. Finally, the system was pulled back safely, and the entrapped burr was retrieved without complications. This approach may be useful and safe when coronary flow is preserved despite the trapped burr.
