1. A prosthetic heart valve, comprising:
a stent having an inflow end, an outflow end, an expanded condition, a collapsed condition, and a length in a longitudinal direction from the inflow end to the outflow end, the stent including an annulus portion having a plurality of closed perimeter cells adjacent the inflow end, an aortic portion having a plurality of closed perimeter cells adjacent the outflow end, and an intermediate open area between the annulus portion and the aortic portion that, in the expanded condition, is enlarged relative to the closed perimeter cells in the annulus portion and the closed perimeter cells in the aortic portion;
a plurality of valve leaflets operatively supported by the stent; and
a cuff connected to the stent and having an inside wall and an outside wall, the inside wall having a length in the longitudinal direction that is greater than a length of the outside wall in the longitudinal direction.
