Abstract
A prosthetic heart valve can include a radially expandable and compressible frame having an inflow end, an outflow end, and a plurality of struts. The prosthetic valve can further include a valvular structure comprising a plurality of leaflets, each leaflet comprising a coaptation edge portion and a cusp edge portion. The cusp edge portion of each leaflet can be folded toward the outflow end of the frame along a bending axis and a reinforcing member extends along an outflow surface of the cusp edge portion along the bending axis. The prosthetic heart valve can include a plurality of connecting skirts, each disposed between the cusp edge portion of an adjacent leaflet and the frame. First stitching secures the reinforcing member and the connecting skirts to the cusp edge portions and second stitching secures the connecting skirts to selected struts of the frame.
