Rotablator Burr Disconnection and a Gap Predictor.

ABSTRACT: Disconnection of the rotational atherectomy (Rotablator) burr during rotational atherectomy is an extremely rare complication, the precise etiology of which remains unclear. At our institution, we have encountered 6 cases of burr disconnection over a period of 16 years. The target vessels were the right coronary artery in 4 cases and the left circumflex artery in the remaining 2 cases. Burr disconnection occurred within a stent in 4 of these cases. Two cases were accompanied by guidewire fracture, necessitating emergency surgical intervention, whereas the guidewire remained intact in the remaining 4 cases, allowing successful retrieval of the burr by pulling the guidewire. Immediately before burr disconnection, a gap between the burr and the drive shaft was occasionally observed, which we
