N2 - AIMS: As data on the use of the latest-generation drugeluting stents (DES) in bifurcation interventions are lacking, we realized a multicenter registry to assess the procedural and clinical results obtained in patients with unselected bifurcated lesions treated with the novel zotarolimus-eluting Resolute stent (ZRS).
METHODS AND RESULTS: Three Italian centers participated in the study. Consecutive patients with significant stenosis of bifurcated lesions undergoing DES implantation were treated with ZRS. The recommended technique was the "provisional TAP approach" [main-vessel (MV) stent implantation eventually followed by kissing balloon and sidebranch (SB) stenting according to TAP technique]. Clinical characteristics, procedural details and clinical follow-up data were prospectively recorded. Procedural success was defined as post-percutaneous coronary intervention visual stenosis > 20% on MV and TIMI 3 flow on both MV and SB. Primary endpoint was major adverse coronary events (cardiac death, myocardial infarction and target vessel revascularization) at 9-month follow up. A total of 180 patients were enrolled. The target lesion was located in the distal left main in 16% and in the left anterior descending artery in 52%. All but 3 cases were treated according to the provisional TAP approach (kissing balloon rate, 69%; overall SB stenting rate, 10.6%). Procedural success was obtained in 98.3% (3 failures due to final SB TIMI flow < 3). At 9-month follow up, the survival free from MACE was 97.8% (1 cardiac death and 3 repeat revascularizations).
CONCLUSION: The use of the latest-generation ZRS in unselected bifurcated lesions treated by a provisional approach is associated with excellent procedural results and with promising clinical outcomes.
