Claim 0:
1. A prosthetic heart valve, comprising:
an annular spacer configured to engage a native heart valve, the annular spacer comprising:
a cylindrical skirt having an upstream end and a downstream end opposite from the upstream end, wherein a spacer opening extends through the cylindrical skirt between the upstream end and downstream end thereof, and
a disc-shaped wall situated about a portion of the cylindrical skirt and extending radially outward from the cylindrical skirt; and

a central valve section configured for disposal within the spacer opening of the annular spacer, the central valve section having:
a hollow valve section body configured to support a valve prosthesis therein, and
at least one anchoring protrusion configured to extend radially outward from the valve section body, the at least one anchoring protrusion being configured to prevent the central valve section from moving axially relative to the annular spacer,
wherein the central valve section is configured to:
expand radially within the heart from a delivery configuration into an at least partially-expanded configuration while at least a portion of the central valve section is situated outside of the spacer opening of the annular spacer, and
move into the spacer opening, while the central valve section remains in the at least partially-expanded configuration, until the at least one anchoring protrusion contacts the downstream end of the cylindrical skirt, and

wherein the cylindrical skirt of the annular spacer is configured to be inverted such that a first end of the cylindrical skirt is situated upstream of the disc-shaped wall after deployment of the annular spacer within the native heart valve, the first end of the cylindrical skirt being the downstream end of the cylindrical skirt when the cylindrical skirt is in a non-inverted configuration.
