Unintended stent extraction from a coronary artery during bifurcation coronary angioplasty.

We report an elective angioplasty of a left circumflex artery (LCx) bifurcation lesion treated by provisional stenting. With a "jailed" wire in the first obtuse marginal, we deployed a 3.0 x 28 mm drug-eluting stent into the main branch. The jailed wire was tangled up in a tortuous side branch. We were unable to retrieve the wire. Forceful wire removal led to an unintended extraction of the fully deployed stent from the main branch.
