Patent abstract
A method and device for reducing paravalvular leakage upon implantation of a replacement heart valve is provided. The valve assembly includes a tissue or bioprosthetic heart valve attached to an anchoring structure. The anchoring structure includes an inlet rim that is substantially C-shaped in cross section to form a concave landing zone. The anchoring structure self-seats when implanted in the sinus of a patient with the proximal and distal ends of the C-shaped inlet rim pushed against the aorta to effectively prevent paravalvular leakage.
