Nano Crush Stenting Technique

ABSTRACT

In approximately one-third of bifurcation lesions, a double stent strategy is necessary, and these lesions are associated with a heightened rate of restenosis and the need for repeat revascularization following the proce- dure. Nano-Crush stenting technique was developed specifically for true bifurcations (Medina 0,1,1 or 1,1,1) with complex anatomical structures. This technique is a Mini-Crush stenting modification to minimize the protru- sion of the side branch (SB) stent into the main vessel. The Nano-Crush technique limits the SB stent protru- sion to just one stent cell, reducing metal burden and improving flow dynamics. In the literature, Nano-Crush stenting is described as an operator-friendly method that can be applied to both wide and narrow-angle bifurcation lesions regardless of bifurcation characteristics, offering a shorter procedure time. However, larger randomized studies are required, especially to assess long-term outcomes.
