Burr entrapment is a rare and challenging complication of rotablation. This section looks at several techniques employed today to retrieve an entrapped burr including a retrieval method involving a guide extension catheter combined with a snare which could be used to successfully respond to this complication.

Burr entrapment is seen to occur for several reasons: if a burr slips across the lesion without the burring (the coefficient of friction is less at high speed than at the rest), the ledge of the calcium behind the elliptical burr causes a Kokeshi phenomenon, or the burr may get entrapped in the tortuous segment of the lesion. While a surgeon should be called immediately, several approaches are available. A guide extension catheter can be passed over the shaft of the entrapped burr, a se...
