1. A prosthetic heart valve, comprising:
a radially expandable and compressible frame having an inflow end portion and an outflow end portion, the frame comprising a plurality of struts defining openings between them; and
a valvular structure comprising a plurality of leaflets, each leaflet comprising a main body, opposing tabs on opposite sides of the main body, a coaptation edge portion, and a cusp edge portion, each tab being paired with an adjacent tab of an adjacent leaflet to form a plurality of commissures that are fixed relative to the frame, and wherein each leaflet has opposing edge portions between the opposing tabs and the cusp edge portion that are unattached to the frame, each unattached edge portion defining a gap that extends radially into the main body of the leaflet, each gap being disposed upstream of a respective commissure of the plurality of commissures;
wherein the tabs of each leaflet are upper tabs and wherein each leaflet further comprises opposing lower tabs on the opposite sides of the main body, the lower tabs being spaced from the upper tabs by the unattached edge portions, wherein each lower tab is folded toward the main body of the leaflet.
