Novel self-expanding stent system for enhanced provisional bifurcation stenting: Examination by StentBoost and...

A 62-year-old man underwent percutaneous coronary intervention of a bifurcation lesion (Medina type 010) involving the mid-left anterior descending coronary artery and an important first diagonal branch with a novel stent specifically designed for bifurcations, the Stentys coronary bifurcation system. This is a self-expanding nitinol stent, with Z-shaped struts linked by interconnections that can be disconnected (in prespecified points every 1.5 mm all around the circumference and the length of the stent) at the level of the ostium of the side branch, simply by inflating an angioplasty balloon tracked to the ostium of the side branch, through the stent struts. The steps required for deployment of the stent and the final result obtained were evaluated by intravascular ultrasound examination and StentBoost Subtract, a specific X-ray stent-enhancing visualization technique.
