Mechanism and management of burr entrapment: A nightmare of interventional cardiologists
Case 4 was a 74-year-old male with left main (LM) bifurcation disease and received bypass surgery years ago. PCI for the LM bifurcation and calcified LAD lesions was performed because all the bypass grafts were occluded. RA for the heavily calcified LAD was attempted using a 1.5 mm burr. However, it was stuck beyond a stenotic calcified lesion. A Conquest wire was passed distally followed by 2.5 mm balloon inflation at the stenotic lesion to retrieve the entrapped burr successfully (). After stenting for the LAD, the LM bifurcation was successfully treated by simultaneous kissing stenting.
