Devices and methods for reshaping a mitral valve annulus are provided. One preferred device is configured for deployment in the right atrium and is shaped to apply a force along the atrial septum. The device causes the atrial septum to deform and push the anterior leaflet of the mitral valve in a posterior direction for reducing mitral valve regurgitation. Another preferred device is deployed in the left ventricular outflow tract at a location adjacent the aortic valve. The device is expandable for urging the anterior leaflet toward the posterior leaflet. Another preferred device comprises a tether configured to be attached to opposing regions of the mitral valve annulus.
