Mechanism and management of burr entrapment: A nightmare of interventional cardiologists
Case 5 was a 72-year-old woman who was admitted for stable angina. Heavily calcified LAD and left circumflex artery (LCX) were found and a 1.25 mm burr was employed first for the LCX lesion. During the pecking motion of rotablation, the burr was suddenly trapped at middle LCX and could not be retrieved (). The entrapped burr was removed by manual traction of the burr and guide wire, which resulted in injury and acute closure at the ostium of LCX. Intra-aortic balloon pump was inserted for hemodynamic support and antegrade flow of LCX was restored by successful re-wiring and stenting.
