This disclosure relates generally to prosthetic valves and methods and systems for deploying, positioning, and recapturing the same. A prosthetic valve includes one or more support structures. At least one of the one or more support structures defines an elongate central passageway of the prosthetic valve. The prosthetic valve can also include a plurality of leaflet elements attached to at least one of the one or more support structures and disposed within the elongate central passageway for control of fluid flow through the elongate central passageway. At least one of the one or more support structures is configured to biodynamically fix the prosthetic valve within a native valve such as, for example, a native tricuspid valve of a heart.
