Aims: The long-term impact of treating bifurcation lesions on the overall outcome of patients with multivessel coronary disease treated percutaneously with drug-eluting stents is unknown. This analysis determined the influence of bifurcation treatment using sirolimus-eluting stents on 3-year clinical outcomes. Methods and results: Of the 607 patients (2,160 lesions) in the ARTS II study, 324 patients underwent revascularisation procedures involving treatment of at least one bifurcation (465 lesions). Three-year outcomes were compared to those without bifurcations. Despite more diffuse and complex disease in the bifurcation group, survival free of adverse events was equivalent in the two groups. At 3-years, there was no difference in rate of overall MACCE (20.2% vs. 18.5%, p=NS) or any of the component events between the bifurcation and the non-bifurcation group. There was a trend for a higher rate of definite stent thrombosis in the bifurcation group (4.6 vs 2.1%, p=0.1), but in multivariate analysis the CK value post-procedure served as the only independent predictor of definite stent thrombosis (p=0.015), with the presence of a bifurcation lesion of borderline significance (p=0.056). Conclusions: In multivessel disease treated by PCI with DES, the presence of bifurcation disease had no adverse influence on 3-year clinical outcomes.
