Mitral Valve Translocation: Optimization of Patch Geometry in an Ex Vivo Model of Secondary Mitral Regurgitation

摘要

Abstract Optimal translocation patch width for functional mitral regurgitation (FMR) treatment was evaluated in an air-filled ex vivo system. FMR was created in 19 isolated swine hearts by annular dilation and papillary muscle displacement. Frustum-shaped pericardial patches of varying widths (Group 1?=?0.5?cm; Group 2?=?1.0?cm; Group 3?=?1.5?cm) were implanted and imaged via a 3D-structured light scanner. Median leaflet coaptation decreased (P?
