PG - 1775-1783 LID - 10.1002/ejhf.2321 [doi] AB - AIMS: We report the 2-year outcomes of the MitrAl ValvE RepaIr Clinical (MAVERIC) trial. Functional mitral regurgitation (FMR) is associated with poor outcomes for which there remains an unmet clinical need. ARTO is a transcatheter annular reduction device for the treatment of FMR and an emerging alternative for patients at high surgical risk. The MAVERIC trial was designed to evaluate the safety and performance of the ARTO system in FMR and heart failure (HF). METHODS AND RESULTS: MAVERIC is an international multicentre, prospective, single arm study enrolling patients with FMR grade >/= 2, New York Heart Association (NYHA) class >/=II symptoms despite maximal medical therapy. Patients were excluded if they had significant structural mitral valve abnormality or life expectancy <1 year. The primary outcome measures were a composite safety outcome and efficacy defined as mitral regurgitation (MR) reduction 30 days post-procedure. Secondary outcome measures included safety, change in MR grade, NYHA class and hospitalization for HF at 2 years. Forty-five patients were enrolled. The composite safety outcome was met (2/45 adverse events at 30 days) and no device-related deaths occurred at 2-year follow-up. A sustained reduction in MR [grade < 2: 21/31 (68%) vs. 31/31(0%); P < 0.0001], left ventricular end-diastolic volume index (90.0 +/- 30 vs. 106 +/- 26 mL/m(2) ; P = 0.004) and anteroposterior diameter (35.5 +/- 4.7 vs. 41.4 +/- 4.6 mm; P < 0.0001) was seen at 2 years compared to baseline.
