1. A prosthetic valve configured to be diametrically collapsible into a compact delivery configuration, the prosthetic valve comprising:
a support structure having an outer side and an inner side and a central longitudinal axis and including a frame including a plurality of frame members and a plurality of commissure posts, the frame extending from a distal end to a proximal end, the distal end having a first diameter and the proximal end having a second larger diameter such that the frame has a diametric taper defining a decrease in diameter in a distal direction between the distal end and the proximal end, the diametric taper including a proximal taper, a distal taper, and an intermediate taper between the distal taper and the proximal taper, the proximal taper defining a proximal taper angle relative to the central longitudinal axis of the frame when the prosthetic valve is in an unloaded state, the intermediate taper defining an intermediate taper angle relative to the central longitudinal axis of the frame when the prosthetic valve is in an unloaded state, and the distal taper defining a distal taper angle relative to the central longitudinal axis of the frame when the prosthetic valve is in an unloaded state, the proximal taper angle being different from the intermediate taper angle and the distal taper angle being different than the intermediate taper angle; and
a leaflet construct including a plurality of leaflets spaced circumferentially about the leaflet construct, the plurality of leaflets being operatively coupled to the frame;
wherein the distal taper angle is greater than the intermediate taper angle when the prosthetic valve is in an unloaded state.
