1. A prosthetic heart valve device comprising:

  • an anchoring member comprising a radially expandable frame defining an interior, an upstream portion, and a downstream portion, wherein the upstream portion includes a tissue fixation portion configured to press outwardly against tissue located at and/or downstream of a native annulus of a heart valve, and wherein the tissue fixation portion is at least partially deformable to conform to a shape of the tissue;

    a valve comprising at least one leaflet movable from a closed position in which blood flow is blocked through the interior of the anchoring member and an open position in which blood flow is allowed through the interior of the anchoring member in a flow direction from the upstream portion toward the downstream portion, wherein the valve is spaced inwardly apart from the tissue fixation portion of the anchoring member such that the valve remains competent when the tissue fixation portion is deformed to conform to the shape of the tissue; and

    an extension member extending laterally away from the upstream portion of the anchoring member in a deployed configuration, wherein the extension member comprises a plurality of discrete fabric segments having a first end at the anchoring member and a second end spaced apart from the anchoring member, wherein the fabric segments are arranged side-by-side around the extension member and adjacent fabric segments are loosely coupled together by corresponding sutures such that the second ends of adjacent fabric segments can be positioned independently of each other in the deployed state.
