Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band having an elongate and arcuate body. The elongate and arcuate body 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 displaced from the plane containing the first end and the second end. The transvalvular band is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets and the central portion is displaced towards the left ventricle relative to the first anchoring portion and the second anchoring portion. The ventricular direction displacement moves coaption to an earlier point in the cardiac cycle.
