A transcatheter valve prosthesis includes a stent and a prosthetic valve. The stent includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. The transition portion includes a plurality of axial frame members, and three of the plurality of the axial frame members are commissure posts. At least two of the plurality of the axial frame members are commissure posts having a first end connected to a crown of the inflow portion and an unattached second end disposed within the outflow portion such that a pair of struts of the outflow portion intersect each commissure post at a mid-portion thereof. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent.
