Abstract
A prosthetic heart valve and associated methods for assembling a prosthetic heart valve including a plurality of leaflets is disclosed. As one example, a prosthetic heart valve includes a frame; a plurality of commissure support elements, each connected the frame and including two axially-extending members spaced apart from one another to form a window; and a plurality of leaflets, each leaflet comprising a body and two opposing commissure tabs, each commissure tab arranged adjacent to another commissure tab to form a pair of commissure tabs that are disposed in a commissure support element to form a commissure. Each commissure tab includes a series of overlapping layers that include a first set of two overlapping layers that extends through the window and a second set of two overlapping layers that extends away from the first set of two overlapping layers and over an outer side of a corresponding axially-extending member.
