Abstract
A valve prosthesis can be configured to be deployed within a native heart valve and prevent axial flow of fluid around an exterior of the prosthesis. The prosthesis can include an expandable frame configured to radially expand and contract for deployment within the native heart valve, a flap assembly positioned around an exterior of the expandable frame, a proximal end of the flap assembly being positioned at or proximate a proximal end of the expandable frame. In some embodiments, the flap assembly can extend outward from the frame and have an expanded configuration configured to create a barrier to fluid flow exterior to the frame when deployed within the native heart valve.
