A prosthetic mitral valve with a compressible and expandable stent that, when expanded, is circumferentially oval, elliptical, or D-shaped, with a major axis and a minor axis ratio of from about 3:4 to about 4:5. Embodiments of the stent comprise three commissure posts disposed towards an outflow end and three curved cusp regions between adjacent commissure posts. Three flexible leaflets are attached to the commissure posts in a tri-foil configuration. Embodiments of the prosthetic mitral valve include an atrial ring disposed at the inflow end of the stent. |
