Abstract:Objective Currently, mitral prosthetic rings are intended only to reshape the annulus. We present in vivo results of an innovative device characterized by an intraventricular segment designed to enable artificial chordae implantation and simplify leaflets and subvalvular apparatus correction. Methods: Eight sheep were employed. The first 4 underwent solely device implantation. In the last 4, primary chordae of the anterior leaflet (A2) were torn to induce severe mitral regurgitation. The severed chordae were r… Show more
