Copyright © 2023. Published by Elsevier Inc; METHODS: EXPAND is a prospective, multicenter, international, single-arm study that enrolled patients with primary MR and secondary MR at 57 centers. Follow-up was conducted through 12 months. Echocardiograms were analyzed by an echocardiographic core laboratories. Study outcomes included: MR severity, functional capacity measured by New York Heart Association functional class, quality of life measured by Kansas City Cardiomyopathy Questionnaire, heart failure hospitalizations, all-cause mortality; OBJECTIVES: The EXPAND study evaluated contemporary real-world outcomes in subjects with mitral regurgitation (MR) treated with the third-generation MitraClip NTR/XTR transcatheter edge-to-edge repair system; RESULTS: 1,041 patients were enrolled from April 2018 through March 2019, of which 50.5% had primary or mixed etiology. Implant success was 98.9%; 1.5 +/- 0.6 clips were implanted per subject. Significant MR reduction from baseline (>=MR 3+: 56.0%) to 30 days (<=MR 1+:88.8%) was maintained through 1 year (MR <=1+: 89.2%). A total of 84.5% and 93.0% of subjects in primary MR and secondary MR, respectively, had <=1+ MR at 1 year. Significant improvements were observed in clinical outcomes (New York Heart Association functional class I/II in 80.3%, +21.6 improvement in Kansas City Cardiomyopathy Questionnaire score) at 1 year. All-cause mortality and heart failure hospitalizations at 1 year were 14.9% and 18.9%, respectively, which was significantly lower than previous studies UR - https://dx.doi.org/10.1016/j.jcin.2023.01.010 ER -
