(A) High magnification scanning electron microscopy images of the leaflet attachment sites in pig 15P100 depicting complete endothelialization of the neoleaflet region; (B) Similar endothelialization of the papillary muscle attachment section in the same pig. (C) Atrial view of the mitral valve from pig 15P100, depicting slight yellow color of the posterior leaflet opposite to the device; (D) Movat’s pentachrome staining depicted local thickening with focal hemosiderin deposits without any discrete injury to the leaflet that could be identified on these sections.
