Clinical experience with CorMatrix extracellular matrix in the surgical treatment of mitral valve disease.

Objectives: To determine the clinical utility of an acellular bioscaffold as a structural material for mitral valve repair (MVr).

Methods: This was a retrospective study of patients undergoing partial or subtotal leaflet replacement and/or leaflet extension to treat mitral regurgitation or acute endocarditis and/or reconstruction of atrial-ventricular continuity after annular decalcification. The material used for repair was a bioresorbable extracellular matrix (ECM) material indicated for cardiac tissue repair (CorMatrix Cardiovascular, Inc, Roswell, Ga).
