More Information
Summary:A prosthetic heart valve includes a valve ring, which includes metal segments, and which is cylindrical when in an expanded state. A valve ring fabric sleeve is coupled to the valve ring. A leaflet frame is disposed within the valve ring. A plurality of prosthetic leaflets are coupled to the leaflet frame. An upper skirt includes an upper skirt fabric, coupled to the valve ring fabric sleeve; and a flexible upper skirt frame, coupled to the upper skirt fabric such that the upper skirt fabric separates a downstream end of the upper skirt frame from an upstream end of the metal segments of the valve ring. When the prosthetic heart valve is in an expanded state, the upper skirt extends radially outward from the valve ring in an upstream direction and is configured to rest against an atrial surface of the heart. Other embodiments are also described.
