Abstract:
Objective To evaluate long-term outcome of simultaneous kissing sirolimus-eluting stent (SKS) technique versus single sirolimus-eluting stent (SSS) technique for percutaneous treatment of true coronary bifurcation lesions in large-size vessels.Methods This randomized study assigned 190 patients with a coronary bifurcation lesion to simultaneous kissing stenting (SKS) in both main and side branches and 190 patients to main vessel stenting only (SSS).The endpoints included restenosis,death,non-fatal myocardial infarction,target-lesion revascularization (TLR),stent thrombosis,success rate of percutaneous coronary intervention (PCI) and the operation duration.Results During 1-year follow-up,the SKS group and the SSS group had similar incidences of overall re stenosis [30 ( 15.8 ％ ) vs.24 ( 15.2 ％ ),x2=0.000,P＜0.05],mainbranch restenosis [20 ( 10.5％ ) vs.16 ( 10.1％ ),x2=0.003,P ＞ 0.05];side-branch restenosis [13 ( 6.8％ )vs.23 ( 14.6％ );x2=4.73,P＜0.05];death [2 ( 1.1％ ) vs.1 ( 0.6％ ),x2=0.026,P ＞ 0.05],non-fatal myocardial infarction [4 (2.1％ ) vs.2 ( 1.3％ ),x2=0.034,P ＞ 0.05],TLR [23 ( 12.1％ ) vs.20 ( 12.7％ ),x2=0.000,P ＞ 0.05] and stent thrombosis [4 (2.1％ ) vs.2 ( 1.3 ％ ),x2=0.034,P ＞ 0.05] and a shorter operation duration[(20 ± 8) min vs.(45 ± 9) min,t=1.98,P＜0.05] than the SSS group.Conclusion For true coronary bifurcation lesions in large-size vessels,SKS and SSS have similar long-term outcomes.The SKS group has a higher success rate of PCI and shorter operation duration.
