Embodiments of the stent comprise three commissure regions disposed towards an outflow end and three curved cusp regions between adjacent commissure regions. Three flexible leaflets are attached to the commissure regions in a tri-foil configuration. Embodiments of the prosthetic mitral valve include an atrial ring disposed at the inflow end of the stent.
