Intentional switch between 1.5-mm and 1.25-mm burrs along with switch between rotawire floppy and extra-support for an uncrossable calcified coronary lesion.

ABSTRACT: Rotational atherectomy (RA) is considered to be the last resort for a severely calcified coronary artery lesion. Severe complications such as vessel perforation or burr entrapment is closely associated with forceful burr manipulation during RA. The instructions for use of Rotablator (Boston Scientific, Marlborough, MA, USA) prohibit forceful burr manipulation when rotational resistance occurs. Nevertheless, RA operators tend to forcefully manipulate the burr if it cannot cross the lesion, because there has been no established strategy for an uncrossable lesion. We present a case with a severely calcified coronary lesion, which was uncrossable by a burr 1.5 mm with RotaWire Floppy (Boston Scientific). We intentionally switched 2 burrs (1.5-mm and 1.25-mm) and 2 RotaWires (Floppy and Extra-s
