Figure 2 Mini-Crush Stenting With 2-Step Kissing Balloon Post-Dilation in a Phantom Through an 8-F Guide

Mini-crush differs from classical crush in that the proximal end of the SB stent is positioned adjacent to the proximal end of the SB ostium (A, arrow) so that a minimal length of SB stent is crushed (B to D). Two-step kissing involves first a high pressure (>20 atm) post-dilation of the SB ostium with a noncompliant balloon 0.25 mm smaller in diameter than nominal SB diameter (F), and then the final kissing balloon post-dilation typically at 8 to 10 atm to correct any stent distortion (G). Abbreviation as in Figure 1.
