Fadi J. Sawaya et al. JCIN 2016;9:1861-1878 Double Kissing Crush Technique Step by Step (1) Side branch (SB) stenting with short main branch protrusion. (2) SB stent balloon crush. (3) SB wire recrossing. (4) First kissing balloon inflation. (5) Main branch stenting across the SB after SB wire is removed. (6) Proximal optimization technique. (7) Second SB wire recrossing through the main branch stent and the crushed SB stent. (8) Second kissing balloon inflation. (9) Re–proximal optimization technique. (10) Final result. Fadi J.
