PERFORMANCE AND HEALING OF AN EXPANDED POLYTETRAFLUOROETHYLENE MULTI CHORDAL DEVICE AT 6-MONTHS AFTER REPAIR OF MITRAL LEAFLET FLAIL IN SWINE

Central picture legend : A device with a papillary muscle section, multiple chordae with neoleaflets for mitral repair. CENTRAL MESSAGE: The multi-chordal mitral repair device, has a theoretical benefit in performing complex mitral repairs. This study reports the 6-month feasibility and performance of this device in swine. PERSPECTIVE STATEMENT: A general tendency exists to choose mitral valve replacement over mitral valve repair, in lesions that are complex from involvement of multiple cusps. A device design that can simplify repair, despite lesion complexity, can encourage surgeons without concentrated mitral repair experience to adopt repair into their everyday practice.
