Unravelment of Medtronic Onyx stent during bifurcation stenting using the jailed wire technique; An adverse effect of helical stent structure?

A 62-year old male underwent treatment of a bifurcation lesion in the left anterior descending coronary artery using provisional stenting with a jailed wire technique. Severe longitudinal stent deformation and unravelment of the stent part proximal of the bifurcation occurred when we tried to pull the jailed wire from the side branch. The described case poses a caution on the use of this specific stent(-design) in bifurcation lesions.
