Randomized study on T stenting and small protrusion technique versus simple stenting for patients with coronary artery bifurcation lesions and with big size side branch / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>A total of 142 eligible patients were recruited and 127 patients completed the study (simple stenting group 58 and TAP technique group 69).</p><p><b>RESULTS</b>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 rate 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 lower than that of simple stenting group (17.1% versus 3.8%, P < 0.05). Overall restenosis rate was similar between the groups (P > 0.05).</p><p><b>CONCLUSION</b>Both TAP technique and simple stenting are feasible and effective strategies for treating patients with bifurcation lesions.</p>
