ABSTRACT:
A valve prosthesis includes a plurality of flexible leaflets and a stent having a central lumen. A slit in the stent extends from the central lumen to an outer surface. An occluding portion of the flexible leaflets extends across the central lumen and an attachment portion extends from the central lumen through the slit and forms a sewing cuff for attachment to a patient's tissue. The attachment portion forms a sewing cuff for attachment to native heart tissue.
