Despite the mechanical complexity of the Rotablator system, device failure is a rare event. However certain complications may occur during the rotational atherectomy (RA) procedure including slow or no reflow, coronary spasm, distal embolisation, coronary dissection, coronary perforation[1], guidewire (GW)[2] fracture, or the disconnection of the drive shaft and entrapment of burr. As the majority of device failure cases are due to the use of this device outside standard procedures, the goal of this section is to increase awareness of the proper clinical approach to RA and thus be able to quickly identify the origin of the complication and be prepared for treating it.

In the case of rota burr or shaft disconnection, the burr has become stuck and when an attempt is made to take it o...
