DK crush stenting techniques

A) One balloon was introduced into the MV and the SB stent. B) & C) The balloon in the MV was then inflated to crush the SB stent after its deployment. D) After rewiring the SB proximally, a first kissing was performed. E) Stenting the MV. F) & G) Final kissing balloon inflation was conducted after rewiring the SB from the proximal MV stent cell. H) & I) After stenting both the MV and the SB, the proximal optimisation technique (POT) should be performed to improve MV stent strut apposition. DK: double kissing; MV: main vessel; SB: side branch
