Abstract
A prosthetic heart valve includes a balloon-expandable stent including a plurality of struts and a plurality of commissure posts, each commissure post containing an elongated slot. A plurality of leaflets is made from pericardial tissue and includes flaps. An intermediate polymer sheet is disposed between the stent and the plurality of leaflets. At least one reinforcing polymer core is attached to at least one leaflet and the intermediate polymer sheet using stitches that loop around an end of the at least one leaflet. A plurality of patches covers the elongated slots of the commissure posts, the flaps of the leaflets being attached to the patches. A cuff contacts an exterior of the stent, the cuff and the intermediate polymer sheet sutured to one another so as to cover an axial end of the stent.
