Mechanism and management of burr entrapment: A nightmare of interventional cardiologists
Case 2 was a 65-year-old gentleman with type 2 diabetes and dyslipidemia, who was admitted for PCI because of unstable angina. Heavily calcified from proximal to distal LAD was revealed by both angiography and intravascular ultrasound. Rotablation using a 1.5 mm burr was performed at a speed of 180,000 r/min. The burr was entrapped at the distal LAD during a long run of more than 10 s (). The stuck burr was retrieved by pulling vigorously on the guiding catheter (GC), GW and rotablator burr simultaneously. However, it resulted in a spiral dissection and acute closure at the distal LAD, which was successfully rescued by re-wiring and stenting.
