1. An expandable prosthetic valve for implantation within a native mitral valve, the prosthetic valve being expandable from a radially contracted state to a radially expanded state, the prosthetic valve comprising:

  • an expandable annular outer frame having an atrial end and a ventricular end;

    an expandable inner frame situated at least partially within the annular outer frame and having an atrial end and a ventricular end, the inner frame further including one or more tissue anchors extending therefrom; and

    one or more tissue anchors extending from the annular outer frame,wherein the annular outer frame and the inner frame are configured and interconnected in a manner such that radial expansion of the prosthetic valve from the radially contracted state to the radially expanded state decreases a distance between the ventricular end of the annular outer frame and the ventricular end of the inner frame, andwherein a connection between the inner frame and the annular outer frame is located at a portion of the prosthetic valve spaced apart from the atrial and ventricular ends of the inner frame and from the atrial and ventricular ends of the annular outer frame.
