Schematic illustration of the culotte technique. First, wire both vessels and perform balloon predilation. (A) Deploy first stent from proximal MV to SB. (B) Rewire distal MV and dilate through the stent struts. (C) Deploy second stent from proximal to distal MV. (D) Rewire the SB and perform FKBI. Finish with POT. Abbreviations: FKBI, final kissing balloon inflation; MV, main vessel; POT, proximal optimization technique; SB, side branch.
