Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve. The stent is mechanically or balloon expandable. The stent has an inflow portion and an outflow portion. The inflow portion includes a plurality of side openings defined by a plurality of crowns and a plurality of struts. The outflow portion has three circumferentially spaced apart commissure posts. The prosthetic valve is disposed within and secured to at least the outflow portion of the stent. The prosthetic valve is configured to block blood flow in one direction to regulate blood flow through a central lumen of the stent. The commissure posts are configured to flex or bend flex radially inwardly to reduce stresses observed during valve loading and thereby improve or increase tissue durability of the prosthetic valve.
