Background: Differences in the impact of the 1- or 2-stent strategy in similar coronary bifurcation lesion conditions are not well understood. This study investigated the clinical outcomes and its predictors between 1 or 2 stents in propensity score-matched (PSM) complex bifurcation lesions.Methods and Results: We analyzed the data of patients with bifurcation lesions, obtained from a multicenter registry of 2,648 patients (median follow up, 53 months). The patients were treated by second generation drug-eluting stents (DESs). The primary outcome was target lesion failure (TLF), composite of cardiac death, target vessel myocardial infarction (TVMI), and ischemia-driven target lesion revascularization (TLR). PSM was performed to balance baseline clinical and angiographic discrepancies between 1 and 2 stents. After PSM (N=333 from each group), the 2-stent group had more TLRs (hazard ratio [HR] 3.14, 95% confidence interval [CI] 1.42–6.97, P=0.005) and fewer hard endpoints (composite of cardiac death and TVMI; HR 0.44, 95% CI 0.19–1.01, P=0.054), which resulted in a similar TLF rate (HR 1.40, 95% CI 0.83–2.37, P=0.209) compared to the 1-stent group. Compared with 1-stent, the 2-stent technique was more frequently associated with less TLF in the presence of main vessel (pinteraction=0.008) and side branch calcification (pinteraction=0.010).Conclusions: The 2-stent strategy should be considered to reduce hard clinical endpoints in complex bifurcation lesions, particularly those with calcifications.

Background: Limited data are available regarding the direct comparison of angiographic and clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) for chronic total occlusion (CTO). Methods and Results: A prospective, randomized, multicenter trial was conducted to evaluate the non-inferiority of a zotarolimus-eluting stent (ZES; Endeavor Sprint®, n=80) to a sirolimus-eluting stent (SES; Cypher®, n=80) in patients with CTO lesion with a reference vessel diameter ≥2.5mm. The primary endpoint was in-segment binary restenosis rate at 9-month angiographic follow-up. Key secondary endpoints included target vessel failure (TVF; including cardiac death, myocardial infarction, and target vessel revascularization) and Academic Research Consortium-defined definite/probable stent thrombosis (ST) within 12 months. The ZES was non-inferior to the SES with respect to the primary endpoint, which occurred in 14.1% (95% confidence interval [CI]: 6.0-22.2) and in 13.7% (95%CI: 5.8-21.6) of patients, respectively (non-inferiority margin, 15.0%; P for non-inferiority <0.001). There were no significant between-group differences in the rate of TVF (10.0% vs. 17.5%; P=0.168) nor in the rate of ST (0.0% vs. 1.3%; P=0.316) during the 12-month clinical follow-up. Conclusions: The effectiveness and safety of ZES are similar to those of SES and therefore it is a good treatment option in patients undergoing PCI for CTO with DESs. (Circ J 2012; 76: 868-875)
