Because rotational atherectomy (RA) has several unique complications, such as burr entrapment, vessel perforation, and slow flow, it is important for interventional cardiologists to be familiar with bailout procedures for such complications. The principal part of bailout procedures is to keep a guidewire in the target coronary artery during the procedure. However, it is not easy to keep a guidewire in the same position during the removal of a burr because the length of the RA guidewires is 300 cm, and the removal of a burr requires collaboration between the primary operator and an assistant. We describe the case of an 83-year-old male with stable angina. We performed RA to the left anterior descending artery, and removed the burr using a KUSABI (Kaneka Medix Corporation, OSAKA, Japan) trapping balloon technique without activating the dynaglide mode. This simple technique would help RA operators remove a burr more reliably than the conventional removal technique.
