Objective To determine independent factors correlated with clinical effects of DK crush and classical crush technique with drug-eluting stents on bifurcation lesions.Methods 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).Results Final kissing balloon inflation(FKBI)success rate was 76%in C and 100%in DK groups(P＜0.001).Dkcrush procedure was characterized by lower unsatisfactory FKBI rate(27.6%VS.6.3%,P＜0.01).Clinical follow-up was available in 100%and angiographic follow-up in 82%patients.The overall restenosi srate was 32.3%in C and 20.3%in DK groups(P=0.01).respectively.Cumulative 8-month MACE was 35.9%in without-FKBI and 19.7%in with-FKBI sub-groups,and 11.4%in DK group(P=0.02).The incidence of stent thrombosis was 3.2%in C group (5.1%without VS.1.7%with FKBI)and 1.3%in Dkgroup(P＞0.05).The predictive factors of MACE included minimal side branch stent lumen diameter and lack of DK crush technique.Conclusion DK crush technique is an alternative of double stenting techniquesin terms of improvement of restenosis and clinical outcomes.
