Objectives : To compare zotarolimus‐eluting stent (Endeavor Sprint®; ZES‐S) and the everolimus‐eluting stent (Xience V®; EES) in the treatment of coronary bifurcation lesions Background : Both these stents have demonstrated good outcomes in the treatment of coronary lesions. However, the outcomes with respect to treatment of bifurcation lesions have yet to be conclusively demonstrated. Methods : In this single centered, nonrandomized, open label study, we treated, between August 2006 and December 2008, 110 bifurcations with ZES‐S and, in a second stage of the study, 129 bifurcations with EES. The primary end point was to compare the rate of major adverse cardiac events (MACE) (death, myocardial infarction, and new target lesion revascularization) in‐hospital and at 12 months of follow‐up. Provisional T stenting was the strategy used in the majority of cases. Angiographic follow‐up was performed only in patients who presented signs or symptoms suggestive of angina or ischemia. Results : There were no significant differences in in‐hospital MACE between the groups (ZES‐S: 8.1%; EES: 6.2%; P = 0.5). At 12 months, the ZES‐S group had significantly more MACE than the EES group (23.1% vs. 4.5%; P < 0.001) and an elevated index of new revascularization of the bifurcation (17.5% vs. 3.2%; P < 0.001). There were no significant differences in mortality (four patients in ZES‐S vs. one in EES; P = 0.14). Conclusion : The treatment of coronary bifurcation lesions using everolimus‐eluting stents results in better outcomes at 12 months of follow‐up than zotarolimus‐eluting stents. © 2011 Wiley Periodicals, Inc.
