[Comparison of DK crush with classical crush technique with drug-eluting stents for the treatment of coronary bifurcation lesions from DKCRUSH-1 study].

Abstract To determine independent factors correlated with clinical effects of DK crush and classical crush technique with drug-eluting stents on bifurcation lesions. 311 patients with bifurcation lesions were randomized to classical (C, n = 156) or double kissing (DK) crush (n = 155) stent implantation group. The primary endpoints included major adverse cardiac events (MACE). Final kissing balloon inflation (FKBI) success rate was 76% in C and 100% in DK groups (P 0.05). The predictive factors of MACE included minimal side branch stent lumen diameter and lack of DK crush technique. DK crush technique is an alternative of double stenting techniques in terms of improvement of restenosis and clinical outcomes.
