1. An implantable prosthetic device, comprising:
a frame that is movable between a radially compressed configuration and a radially expanded configuration, the frame comprising:
a plurality of struts pivotably coupled to one another, each strut comprising a first end portion including one or more first segments and a second end portion including one or more second segments, wherein the one or more first segments are closer to an outflow end of the frame than the one or more second segments, and the one or more second segments are closer to an inflow end of the frame than the one or more first segments; and
a valvular structure comprising a plurality of leaflets mounted in the frame such that a majority of the volume of the leaflets is disposed in a portion of the frame comprising the second portions of the struts;
wherein the one or more first segments have a first width and the one or more second segments have a second width narrower than the first width such that each of the plurality of struts is narrower at the second end portion;
wherein each of the plurality of struts is pivotably coupled to an adjacent strut at an intermediate portion disposed between the first end portion and the second end portion, wherein each intermediate portion has a third width greater than the first width and the second width; and
wherein when the frame is in the compressed configuration, the first end portions of each pair of adjacent struts coupled at their intermediate portions are separated by a first distance and the second end portions of each pair of adjacent struts coupled at their intermediate portions are separated by a second distance, each second distance being wider than each first distance.
