Twenty-four-month update on double-kissing crush stenting of bifurcation lesions

A group of 312 patients who underwent percutaneous coronary intervention for bifurcation lesions at 12 centers in China, Singapore, Thailand, Israel, India, and Japan were enrolled in a prospective, randomized DKCRUSH-1 trial. The goal of the study was to compare the double kissing (DK) crush technique with the classical crush stenting technique. This study was carried out to determine the differences in the rates of final kissing balloon inflations (FKBI) and the long-term clinical outcomes. The 8-month results of the DKCRUSH-1 study have been previously reported. Here, we present several subgroups analysis and a 24-month clinical update. The results confirmed a sustained, lower MACE rate at 24 months with the double kissing (DK) crush stenting technique compared with that for the classical crush stenting technique (18.1% vs. 29.9%, p = 0.044).
