1. A prosthetic heart valve, comprising:
a stent having a collapsed condition and an expanded condition, the stent including a plurality of cells arranged in annular rows around a circumference of the stent, each cell being formed by a plurality of struts, each cell in a first annular row of cells including a runner connecting one cell in the first annular row to an adjacent cell in the first annular row;
a plurality of commissure features disposed on the stent; and
a valve assembly secured to the stent and including a cuff and a plurality of leaflets, each leaflet including a first edge adjacent to the cuff and a free edge spaced apart from the cuff, the first edge of each leaflet having ends, a middle portion and intermediate portions between the middle portion and the ends, the ends being connected to a respective pair of the commissure features, a first one of the intermediate portions being connected only to the cuff along a descending path spaced from a first group of the struts, a second one of the intermediate portions being connected only to the cuff along an ascending path spaced from a second group of the struts, and the middle portion crossing one of the runners and being connected only to the cuff between the descending path and the ascending path.
