US Patent 10531872 Valve prosthesis configured for deployment in annular spacer

Embodiments of the present disclosure are directed to prosthetic heart valves and methods of use thereof. In one implementation, a prosthetic heart valve may include an annular spacer having a spacer opening therein and a disc-shaped wall configured to obstruct blood flow. The annular spacer may be configured for engaging with a native heart valve opening, such as the orifice of a mitral valve. The spacer opening may be sized to be smaller than the native heart valve opening. The prosthetic heart valve may also include a central valve section configured for disposal within the spacer opening. The central valve section may be separate from the annular spacer and may include one or more prosthetic valve leaflets.
