1. A prosthetic treatment apparatus for treating a native mitral valve having a native annulus and native leaflets, comprising:

  • an expandable support having a downstream end configured to be positioned toward a left ventricle, an upstream end configured to be positioned toward a left atrium, and an interior;

    a prosthetic valve having a tri-leaflet assembly mounted to the expandable support and adapted to allow blood flow in the downstream direction and to block blood flow in the upstream direction;

    a plurality of elongated members coupled to a downstream portion of the support and extending outwardly from the support in an upstream direction, wherein the elongated members have sufficient flexibility to deflect inwardly or outwardly relative to the support to accommodate expansion or distortion of the native annulus, and wherein the elongated members are configured to inhibit movement of the support toward the left atrium; and

    a skirt coupled to a downstream portion of the support and extending around the support, wherein the skirt is oriented on the device as to inhibit blood flow between the prosthetic treatment device and the native valve.
