A sealing system for sealing a valve component in a radially expanded deployed configuration to a wall of a native valve includes a valve component and an expandable sealing ring. The valve component has an inflow portion and outflow portion and includes a frame and a prosthetic valve coupled to the frame. The frame defines a central passage with the prosthetic valve disposed therein. The expandable sealing ring is configured to be inserted in a compressed configuration within the central passage of the valve component with the valve component in the radially expanded deployed configuration. The expandable sealing ring is configured to be radially expanded to apply a radially outward force to the valve component, forcing the frame radially outward toward the wall of the native valve.
