Abstract: Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. The band may be implanted via translumenal access or via thoracotomy.
