1. A mitral valve replacement system configured to be implanted in multiple stages to treat a heart having a mitral valve including commissural clefts, a posterior leaflet, an anterior leaflet, and an annulus, comprising:
an anchoring structure including a supra-annular retention structure and anchoring elements at least one of which is configured to engage sub-annular structure of the mitral valve to position the anchoring structure relative to the mitral valve without significantly interrupting the posterior leaflet or the anterior leaflet function; and an artificial valve configured to be received by the supra-annular retention anchoring structure after the anchoring structure is placed separately within the heart; wherein after engagement with the artificial valve the supra-annular retention structure remains spaced supra-annularly of the mitral valve.
