Abstract: Example heart valves are disclosed. An example heart valve may comprise an expandable framework configured to shift from a closed configuration to an expanded configuration, the expandable framework having an inflow end, an outflow end and a lumen extending therein. The heart valve may also include a plurality of valve leaflets coupled to the expandable framework, each of the plurality of valve leaflets including a root edge and a free edge. Further, the heart valve may also include an outer skirt coupled to the plurality of valve leaflets, the outer skirt including a proximal edge, wherein the root edge of each of the plurality of valve leaflets is attached to the proximal edge of the outer skirt.
