### Question: Mitraclip therapy in patients with functional mitral regurgitation and missing leaflet coaptation: is it still an exclusion criterion?

### Context: 1: The aim of this study was to investigate the feasibility, safety, and efficacy of Mitraclip therapy in patients with functional mitral regurgitation (MR) and missing leaflet coaptation (MLC).
2: Out of 62 consecutive patients with functional MR undergoing Mitraclip implantation, 22 had MLC defined as the presence of a 'gap' between two mitral leaflets or insufficient coaptation length (<2 mm), according to the EVEREST II criterion. Compared with the control group, the MLC population had a significantly higher effective regurgitant orifice area (0.67 ± 0.31 vs. 0.41 ± 0.13 cm2; P = 0.019) and sphericity index (0.80 ± 0.11 vs. 0.71 ± 0.10; P = 0.003). MLC patients were treated with pharmacological/mechanical support in order to improve leaflet coaptation and to prepare the mitral valve apparatus for grasping. Implantation of>1 clip and device time were comparable in patients with and without MLC (61.9% vs. 47.5%; P = 0.284 and 101 ± 39 vs. 108 ± 69 min; P = 0.646, respectively). No significant differences were observed between the two cohorts in technical success (95.5% vs. 97.5%, P = 0.667), 30-day device success (85.7% vs. 78.9%; P = 0.525), procedural success (81.8% vs. 75%; P = 0.842), and 1-year patient success (52.9% vs. 44.1%; P = 0.261), defined according to the MVARC (Mitral Valve Academic Research Consortium) criteria. The long-term composite endpoint of cardiovascular death and heart failure hospitalization was similar in the two groups (49.9% vs. 44.4%; P = 0.348). A significant improvement of MR and NYHA functional class and a lack of reverse remodelling were observed up to 2 years in both arms.


###Response: The Mitraclip procedure could be extended to patients with functional MR who do not fulfil the coaptation length EVEREST II criterion and who would otherwise be excluded from this treatment.
