Figure 4 Classical Crush Stenting With Multiple Layers of Struts Compared With Mini-Crush With Minimal Strut Overlap
Driver stents (Medtronic, Minneapolis, Minnesota) (upper panels) after classical crush and Vision stents (Abbott Vascular, Abbott Park, Illinois) (lower panels) after mini-crush have been cut electronically along the planes indicated by the broken line in panels B and E. The electronically cut stents were opened out (panels A, C, D, and F). After classical crush, the crushed portion of the SB stent (C, arrow) has wrapped around 1 side of the MB stent forming 3 layers of struts (C, arrow). By chance, it may have wrapped around the opposite or inferior side. After mini-crush, in contrast, there is minimal multiple layering of struts (F, arrow). Abbreviations as in Figure 1.
