The "double kiss crush" bifurcation technique was first described by Colombo and colleagues in 2004.
- Pre-dilate the main branch (MB) and side branch (SB) if necessary.
- Position a balloon in the MB with the distal tip at the level of the carina.
- Stent the SB with 1-2 mm protrusion in the main vessel (MV).
- Remove the wire and stent balloon from the SB.
- Crush the SB stent with the MB balloon.
- Wire the crushed SB stent proximally.
- Dilate SB stent struts.
- First kissing balloon inflation (KBI).
- Remove SB balloon and wire.
- Stent the MV.
- First proximal optimisation technique (POT).
- SB recrossing.
- Final KBI.
- Final POT.
