Claim 0:
1. A mitral valve prosthesis having a constrained shape and an expanded shape, the mitral valve prosthesis comprising:
a replacement valve attached to a valve-component housing; and
an anchor, the anchor including:
a proximal atrial portion adapted and configured to self-expand from the constrained shape into the expanded shape,
wherein the proximal atrial portion comprises a plurality of wires of shape memory material, and
wherein the proximal atrial portion flares radially outwardly;

a distal portion adapted and configured to self-expand from the constrained shape to the expanded shape, wherein the replacement valve allows blood to flow from the proximal atrial portion toward the distal portion but prevents blood from flowing from the distal portion toward the proximal atrial portion; and
a plurality of hooks extending from the distal portion and extending in a proximal direction to prevent dislodgment of the mitral valve prosthesis into a left atrium;
wherein the valve-component housing is unit of the mitral valve prosthesis that is independent of the anchor of the mitral valve prosthesis and includes a cylindrical central portion connected to the distal portion prior to implantation and extending proximally, wherein when in the expanded shape the cylindrical central portion has a height that is greater than a height of the proximal atrial portion,
wherein the mitral valve prosthesis is rotationally symmetric about a plurality of degrees of rotational symmetry such that the mitral valve prosthesis is adapted for implantation in any rotational orientation corresponding to the plurality of degrees of rotational symmetry relative to a native mitral valve.
