Procedural and late outcomes following MULTI-LINK DUET coronary stent deployment

The MULTI-LINK DUET is the next generation MULTI-LINK stent with modified s trut geometry. Safety and efficacy of the MULTI-LINK DUET were evaluated in a prospective multicenter registry and were compared with prior MULTI-LINK stent experience from the ASCENT randomized trial. A total of 270 patients received 302 MULTILINK DUET stents and were evaluated using a composite pr imary end point of major cardiac events (death, Q-wave and non-Q-wave myoca rdial infarction, and requirement for coronary revascularization) attributa ble to the target stenosis cumulative to 30 days following enrollment. Quan titative coronary angiography was performed at a mean follow-up of 6 +/- 2 (+/-SD) months. No difference in primary end point or in angiographic reste nosis to 6 months was observed between MULTI-LINK DUET and MULTI-LINK exper iences. The MULTI-LINK DUET demonstrated improved device and procedural suc cess, less postprocedural in-stent stenosis, larger postprocedural minimal lumen diameter, and fewer postprocedural marginal dissections compared with the MULTI-LINK stent, Multivariate regression modeling identified stent le ngth, diabetes mellitus, poststent minimal lumen diameter, lesion eccentric ity, and current smoking as independent predictors of in-stent restenosis. Thus, the MULTI-LINK DUET Registry demonstrates enhanced procedural perform ance with clinical and angiographic outcomes similar to those previously ob served for the MULTI-LINK stent in the ASCENT randomized trial.
