[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].
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 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).


CONCLUSIONS
Both TAP technique and simple stenting are feasible and effective strategies for treating patients with bifurcation lesions.
