Neochordal repair of a double orifice mitral valve

Abstract

Native double-orifice mitral valve is an exceedingly rare valvular abnormality. A 77-year-old patient was referred for a severe mitral regurgitation, and a double-orifice mitral valve with a central fibrous bridge was unexpectedly found. A flail anterior leaflet with 2 ruptured chordae was observed on the anterolateral mitral valve orifice, the leaflets on the posterior valve orifice were normally thin. Mitral valve repair was successfully performed with replacement of the 2 torn chordae by two 4/0 expanded polytetrafluoroethylene neochordae. We accordingly suggest that current mitral valve repair techniques remained a valuable option, even on central bridge double-orifice mitral valve regurgitation.
