excision or destruction of *atheroma within an artery using equipment introduced by *catheter. Directional atherectomy involves the use of a device with an incising blade that can be directed to one side of the artery at a time. Rotational atherectomy (rotablation) is achieved with a diamond-tipped drill (burr) that rotates at up to 185,000 times per minute.... atherectomy
