1. A transcatheter valve prosthesis comprising:
a stent having a crimped configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve, the stent including
an inflow portion formed proximate to an inflow end of the stent, the inflow portion including a plurality of crowns and a plurality of struts with each crown being formed between a pair of opposing struts, a plurality of side openings being defined by the plurality of crowns and the plurality of struts, wherein endmost inflow side openings and endmost inflow crowns are formed at the inflow end of the stent,
an outflow portion formed proximate to an outflow end of the stent, the outflow portion including a plurality of crowns and a plurality of struts with each crown being formed between a pair of opposing struts, wherein endmost outflow crowns are formed at the outflow end of the stent, and wherein a total of the endmost inflow crowns are greater than a total of the endmost outflow crowns,
a transition portion extending between the inflow portion and the outflow portion, the transition portion including a plurality of axial frame members, wherein at least two axial frame members of the plurality of axial frame members are commissure posts having a first end connected to a single crown at an outflow end 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, and
a prosthetic valve disposed within and secured to at least the transition portion of the stent, the prosthetic valve being configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent.
