1. A hybrid prosthetic heart valve for implant at a heart valve annulus, comprising:
a valve member having a non-expandable, non-collapsible annular support structure defining a flow orifice and having an inflow end, the valve member having valve leaflets attached to the support structure and mounted to alternately open and close across the flow orifice and a compressible sealing ring encircling the inflow end of the annular support structure;
an expandable stent secured to the inflow end of the annular support structure and extending therefrom to an inflow edge, the stent comprising a generally tubular stent frame formed by struts, the stent frame being covered by a thin fabric layer; and
a flap of fabric having a circular inner edge secured between the stent and the valve member and an outer edge that extends outward adjacent and to an inflow side of the sealing ring and radially outward beyond the sealing ring.
