Effect of a novel transcatheter edge‐to‐edge repair device on the three‐dimensional geometry of mitral valve in degenerative mitral regurgitation

Objectives We sought to assess the acute intraprocedural effects of the ValveClamp system in DMR patients on the mitral valve (MV) three‐dimensional (3D) geometry and the association of these effects with mitral regurgitation (MR) reduction. Background Few data are available about the specific impact of transcatheter edge‐to‐edge repair in patients with degenerative mitral regurgitation (DMR). Methods Thirty‐five symptomatic patients (age 74.26 ± 6.61 years) with Grade 3 to 4+ degenerative MR underwent 3D transoesophageal echocardiography (TEE) during ValveClamp implantation. Volumetric data sets were retrospectively analyzed using mitral valve quantitative 3D modeling software. Results Mitral valve annular anterior–posterior (AP) diameter decreased from 33.24 ± 4.03 to 31.12 ± 3.66 mm (p
