1. An inflatable anchor system for a mitral valve prosthesis, comprising:
a continuous annular balloon capable of being delivered to a native mitral valve of a heart of a patient, on an atrial side of native mitral valve leaflets of the native mitral valve; and
an inflatable anchor formed in a generally annular or semi-annular shape, the inflatable anchor including a portion that is capable of being inflated at a position below a native mitral valve annulus of the native mitral valve, on a ventricular side of the native mitral valve leaflets;
wherein the inflatable anchor is configured for positioning below the native mitral valve annulus, on the ventricular side of the native mitral valve leaflets, and the continuous annular balloon is configured for positioning on the atrial side of the native mitral valve leaflets to assist in anchoring the mitral valve prosthesis by trapping the native mitral valve leaflets between the continuous annular balloon and the inflatable anchor, and
wherein the inflatable anchor comprises discrete inflatable elements for locating between a left ventricular wall and chordae tendinae of the native mitral valve.
