1. A prosthetic heart valve device comprising:

  • a valve support;

    a prosthetic valve having a plurality of leaflets disposed within the valve support;

    an anchoring member having an upstream portion, a downstream portion, and a frame spaced radially outward from and encircling at least a portion of the valve support, the frame having an engagement surface facing laterally outward when the prosthetic heart valve device is in an expanded state, wherein the engagement surface is configured to exert a radially outward force against an inner surface of a native annulus facing the valve support to secure the heart valve device against ventricular systole forces, and wherein the upstream and downstream portion are defined relative to a direction of blood flow through the native annulus; and

    an extension member extending radially outward from the upstream portion of the anchoring member.
