12. A prosthetic valve assembly for assembly to a collapsible and expandable stent, the stent including a plurality of commissure features, each commissure feature including a body having a longitudinal direction extending between a proximal end and a distal end, and a plurality of eyelets arranged in a plurality of columns each extending in the longitudinal direction, the body having a width in a direction orthogonal to the longitudinal direction, the valve assembly comprising:
a plurality of leaflets, each leaflet having a top free edge for coapting with others of the leaflets and including at least one rectangular tab foldable upon itself along a fold line for attaching to a commissure feature at a leaflet-commissure feature junction, the at least one rectangular tab having a width which is at least as long as the width of the body. - View Dependent Claims (13, 14, 15, 16)
