At least one prosthetic leaflet mounted on an inner surface of the stent comprises a free edge, two commissure attachment regions, an attachment edge, a coaptation region, a belly region, and at least one leg structure coupling a portion of the leaflet(s) to a lower ventricular portion of the stent. A sealing skirt coupled to the inner surface of the stent to mount the leaflet(s) and create a paravalvular seal on the atrial portion of the prosthetic hemi valve.
