    Abstract: A prosthetic heart valve has an inner frame and an outer frame that is sutured to the inner frame. The outer frame has an atrial portion and a ventricular portion. The inner frame has a leaflet structure positioned between first and second ends of the metallic inner frame. The prosthetic heart valve has an inflow end and an outflow end, and is radially expandable and collapsible. The prosthetic heart valve has a plurality of tissue-engaging elements positioned along an exterior surface of the outer frame. The outer frame is configured such that in the expanded state the atrial portion of the outer frame extends upwardly beyond an inflow end of the inner frame, and a diameter of the outer frame increases from a first diameter at the outflow end of the prosthetic heart valve to a second diameter moving in an upstream direction toward the inflow end.

    Abstract: A prosthetic valve assembly includes a prosthetic valve and an anchoring frame. The prosthetic valve includes a valve frame and a valve structure. The valve frame includes a plurality of struts and is expandable from a compressed configuration to an expanded configuration. The valvular structure includes leaflets. The valvular structure is disposed radially within and is coupled to the valve frame. The valvular structure is configured to allow blood flow through the prosthetic valve assembly in a first direction and to restrict blood flow through the prosthetic valve assembly in a second direction. The anchoring frame includes a plurality of struts. The anchoring frame is disposed radially outwardly from and is coupled to the valve frame. The struts of the anchoring frame comprise one or more tissue-engaging elements configured for contacting native tissue to help secure the prosthetic valve assembly at an implantation location.
