Abstract: A sealing frame surrounds a radially-outer surface portion of a valve frame of a prosthetic heart valve. Both the valve frame and the sealing frame are radially collapsible and expandable between respective compressed and expanded configurations. The sealing frame has a first axial end coupled to the valve frame at its inflow end, and a second axial end coupled to the valve frame at a location between its inflow and outflow ends. The sealing frame also has an intermediate portion between the first and second axial ends that projects radially outward when the valve and sealing frames are in their expanded configurations. The sealing frame displaces an outer skirt of the prosthetic heart valve radially outward and urges the outer skirt into contact with surrounding native tissue, thereby reducing or avoiding paravalvular leakage. In some examples, the sealing frame can be formed of a shape memory material.
