<p><span>Objectives: This retrospective analysis sought to evaluate 1-month outcomes and therapy effectiveness of a population of patients treated with MitraClip therapy. We describe in this article the preliminary results of primary effictiveness endpoint.</span></p><p><span>Background: Percutaneous Mitral Repair is being developed to treat severe mitral regurgitation (MR),with increasing real-world cases of functional MR(FMR). In the EVEREST(Endovascular Valve Edge-to-Edge Repair Study)II

Repair Study)II trial,percutaneous device showed superior safety but less reduction in MR at 1year. 4-year outcomes from EVEREST II trial showed no difference in the prevalence of moderate-severe and severe MR or mortality at 4years between surgical mitral repair and percutaneous approach.</span></p><p><span>Methods: We analysed retrospectively collected data from one center experience in Italy enrolled from January2011 to December2016. The study included 62patients[mean age74±11years, 43 men(69%)] with MR of at least grade3+. Most of patients had functional MR, were in New York Heart Association(NYHA) functional class III or IV,with a large portion(78%) of mild-to-moderate Tricuspid Regurgitation(TR). One or more clips were implanted in 67procedures(62 patients).<span> </span></span></p><span>Results and Conclusions: Severity of MR was reduced in all successfully treated patients,54(90%) were discharged with MR≤2+(primary effictiveness endpoint). Clinical 1-month follow-up data showed an improvement in NYHA functional class (42patients (70%) in NYHA class I-II). 60 of 62 (97 %) successfully treated patients were free from death and mitral valve surgery at 1-month follow-up. MitraClip therapy reduces functional MR with acute MR reduction to &lt;2+ in the great majority of patients,with a large freedom from death, surgery or recurrent MR in a great portion of patients.</span>
