1. A method of implanting a prosthetic valve within a native mitral valve, the method comprising:

  • delivering the prosthetic valve into a heart chamber while the prosthetic valve is constrained in a radially-contracted delivery configuration, wherein the prosthetic valve includes;

    an annular valve body comprising an annular outer frame and an inner frame situated at least partially within the outer frame,a plurality of ventricular anchors configured to extend from the outer frame, anda plurality of atrial anchors configured to extend from the inner frame,wherein the outer frame and the inner frame are secured against relative axial movement by at least one connector;

    unconstraining the plurality of ventricular anchors and the plurality of atrial anchors while maintaining the valve body in the radially-contracted delivery configuration; and

    unconstraining the valve body from the radially-contracted delivery configuration while the unconstrained atrial anchors are positioned within an atrium and while the unconstrained ventricular anchors are positioned within a ventricle, wherein unconstraining the valve body decreases a longitudinal distance between terminal ends of the unconstrained ventricular anchors and terminal ends of the unconstrained atrial anchors, such that native mitral valve tissue is clamped between the ventricular anchors and atrial anchors.
