Bailout side branch ostium stenting in a true 0,0,1 bifurcation lesion: Crush, rewire and kiss as in the DK-crush technique

Abstract

We report the case an 80-year-old male with troponin-positive acute coronary syndrome due to a tight ostial stenosis of a large diagonal branch. We safely performed the first half of the DK-crush technique to secure with DES implantation the SB of a true 0,0,1 bifurcation lesion in a bailout situation. IVUS confirmed that we could refrain from the subsequent steps as stenting of the main vessel was unnecessary.

Learning objective

Percutaneous coronary intervention in true non-left-main 0,0,1 bifurcation lesion poses several challenges for the optimal technique to be employed whenever stent implantation is desired in the side branch. We demonstrate how it is possible to secure with stent implantation the SB of a true 0,0,1 bifurcation lesion by using intravascular imaging guidance and employing the first half of the DK-crush technique.
