Abstract: Objective To explore the feasibility and safety of T stenting and small protrusion(TAP)technique and compare the efficacy with simple stenting in patients with coronary bifurcation lesions and with big size side branch.Methods A total of 142 eligible patients were recruited and 127 patients completed the study(simple stenting group 58 and TAP technique group 69).Results Major adverse cardiovascular event rate was similar at 12 months follow up between the groups(TAP technique group 13.0%versus simple stenting group 12.1%,P＞0.05).The late of procedural-related myocardial infarction,procedure and fluoroscopy time,contrast volumes were also similar between 2 groups(all P＞0.05).At 8 months,coronary angiography revealed that the restenosis rate of the ostium of side branch in TAP group was significantly lowerthan that of simple stenting group(17.1% versus 3.8%,P＜0.05).Overall restennosis rate was similar between the groups(P＞0.05).Conclusion Both TAP technique and simple stenting are feasible and effective strategies for treating patients with bifureation lesions.
