  5. 5. Mitraclip for DMR <ul><li>In experienced centers, DMR is treated with surgical repair at low risk, long term durability of repair is achieved in the majority of patients </li></ul><ul><ul><li>50% of Euro Heart Survey patients were not referred to surgery (Mirabel EHJ 2007) </li></ul></ul><ul><ul><li>Age and comorbidity increase the risk of surgery (STS database, 2010) </li></ul></ul><ul><ul><li>Surgery is not associated with improved QoL in most elderly patients (Maisano et al EJCTS 2009) </li></ul></ul>
  6. 6. Mitraclip for FMR <ul><li>Surgical treatment of FMR is associated with </li></ul><ul><ul><li>High hospital mortality </li></ul></ul><ul><ul><li>High recurrence rate </li></ul></ul><ul><ul><li>Long hospital stay </li></ul></ul><ul><ul><li>Unproven survival benefit </li></ul></ul><ul><li>Mitraclip for FMR </li></ul><ul><ul><li>Procedure more simple than for DMR </li></ul></ul><ul><ul><li>Improvement of symptoms at low risk </li></ul></ul><ul><ul><li>HRR suggests survival benefit </li></ul></ul><ul><ul><li>Failure does not modify the surgical option </li></ul></ul>
  7. 7. MitraClip anatomical patient selection considerations <ul><li>Moderate to severe MR (Grade 3 or more out of 4 grades) </li></ul><ul><li>Pathology in A2-P2 area </li></ul><ul><li>Coaptation length > 2 mm (depending on leaflet mobility) </li></ul><ul><li>Coaptation depth < 11 mm </li></ul><ul><li>Flail gap < 10 mm </li></ul><ul><li>Flail width < 15 mm </li></ul><ul><li>Mitral valve orifice area > 4cm 2 (depending on leaflet mobility) </li></ul><ul><li>Mobile leaflet length > 1 cm </li></ul>Recommended criteria 1 1. The current patient considerations are based on EVEREST II and commercial European experience to date. The MitraClip Patient Selection Coniderations document has been endorsed by Expert Opinion (Crossroads institute).
