1. A mitral valve prosthesis for implantation in an annulus of a native mitral valve, the mitral valve prosthesis comprising:

  • a frame comprising;

    an inner support structure including an expandable inflow section formed of a plurality of cells and configured to expand within and support against a left atrium and an expandable outflow section formed of a plurality of cells and configured to expand within and support against the native mitral valve annulus,wherein the expandable inflow section has an asymmetrical shape configured to accommodate an anterior horn of the atrium and ensure axial fixation of the valve prosthesis against the left atrium; and

    an outer support structure coupled to the inner support structure including first and second commissure posts and first and second engagement arms, wherein a first end of the first engagement arm is attached to the first commissure post and a second end of the second engagement arm is attached to the first commissure post; and

    a valve including a valve leaflet, the valve being attached to the frame within an interior area of the inner support structure,wherein the first and second commissure posts are parallel to a longitudinal axis of the expandable outflow section of the inner support structure.
