Abstract
A bioprosthetic heart valve includes an outer frame configured to attach to a tissue annulus of a heart and an inner bioprosthetic valve having an exterior shape which substantially matches an interior shape of the outer frame. The exterior shape of the inner valve mates in substantial alignment with the interior shape of the outer frame. An outer frame-inner valve attachment mechanism is configured to couple the inner valve to the outer frame.
