Figure 1 Classical Crush Bifurcation Stenting and 1-Step Kissing Post-Dilation in a Silicone Phantom Through an 8-F Guide
A stent is positioned in the SB with about one-third of its length protruding into the main branch (MB) (A, arrows) and another stent is positioned in the MB. The side-branch (SB) stent is deployed (B and C) and if angiography shows no downstream dissection, the SB balloon and wire are removed. The MB stent is deployed, crushing that portion of the SB stent lying in the MB (D and E). Post-dilation is with simultaneous inflation of a SB and a MB balloon (kissing balloons) typically to about 8 to 10 atm (F). The balloon diameters for kissing post-dilation should be sized to each downstream branch vessel diameter. Final angiography is shown in G and H.
