    Abstract:
    OBJECTIVE: The purpose of this study was to evaluate the long-term outcomes of bifurcation coronary lesions treated with a novel technique called "balloon alignment T-stenting". BACKGROUND: The optimal technique for the treatment of bifurcation coronary disease has not yet been established. METHODS: Twenty-six patients with bifurcation coronary lesions were treated with currently available drug-eluting stent (DES) platforms. This was a pilot study to determine the long-term efficacy of a novel technique, "balloon alignment T-stenting". Based on this technique we performed 6-month anniversary angiography to determine restenosis rates for both main and side branch lesions treated. RESULTS: Twenty-six main branches and 27 side branches were treated with this novel technique. Angiographic 6-month follow up was available for all 26 patients treated. There were no postprocedural mortalities and no cases of postprocedural stent thrombosis during the follow-up period. At 6-month anniversary angiography, no evidence of main branch restenosis was seen. However, there were 2 cases of side branch restenosis for a total side branch restenosis rate of 7.4%. Target lesion revascularization for the 26 patients in the study was 7.6%. The total major adverse cardiac event rate for the group as a whole was 15.4%, with 2 periprocedural non-Q-wave myocardial infarctions and 2 target lesions requiring revascularization at 6 months. CONCLUSION: Using currently available DES platforms, the data compiled from this small, single-center pilot study suggest that balloon alignment T-stenting may represent a reasonable approach for the treatment of bifurcation coronary artery disease. However, more comprehensive, larger-scale trials will be required to validate these preliminary findings.
