BACKGROUND - Data on outcomes of non-left main coronary bifurcation lesions treated with the 2-stent strategy using 2nd-generation drug-eluting stents (DES) are insufficient. Methods and Results: The 2-year outcomes and predictors of target lesion revascularization (TLR) in 356 patients with 364 non-left main coronary bifurcation lesions treated with the 2-stent strategy using 2nd-generation DES were retrospectively evaluated. The primary outcome measure was defined as TLR. The median follow-up duration was 3.6 years (interquartile range, 2.7-4.9 years). A 2-year clinical follow-up was achieved in 99.2%. The 2-year cumulative incidence of TLR was 9.2%. Multiple stents implanted in either the main branch (adjusted odds ratio [OR] 3.01; 95% confidence interval [CI]: 1.37-6.62; P=0.006) or the side branch (adjusted OR 4.55; 95% CI: 1.99-10.4; P<0.001) and the culprit in the left anterior descending artery and its diagonal branch (adjusted OR 0.33; 95% CI: 0.15-0.75: P=0.008) were independent predictors of TLR within 2 years.
