Schematic illustration of the DK crush technique. First, wire both vessels and perform predilation. (A) Deploy first stent to the SB with small protrusion into the MV. (B) Inflate a balloon in the MV to crush the SB stent. (C) Rewire the SB through the stent struts and perform balloon dilation. (D) Perform first KBI. (E) Deploy second stent to the MV. (F) Rewire the SB and dilate the stent struts. (G) Perform second (final) KBI. Finish with POT. Remarks: The main difference between crush and DK crush is the use of first KBI. Abbreviations: DK, double kissing; KBI, kissing balloon inflation; MV, main vessel; POT, proximal optimization technique; SB, side branch.
