Abstract
A prosthetic heart valve can include 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. The prosthetic valve can further include 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 can be paired with an adjacent tab of an adjacent leaflet to form a plurality of commissures that are fixed relative to the frame, and each leaflet can have 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.
