A heart valve prosthesis having a valve housing providing a lumen therethrough. The valve housing has a first annulus on one end and a second annulus on the other end spaced apart from the first annulus. A suture cuff is used for attaching the valve housing to heart tissue of a patient. The cuff is attached between the first annulus and the second annulus. The cuff is positioned such that prosthesis is attached in a supra-annular position relative to a tissue annulus of the heart. The design allows for an increased valve lumen. |
