Beschreibung
Zusammenfassung:	An implantable prosthetic valve includes an annular metallic frame and a valve assembly supported within the frame. The annular support frame is constructed with three longitudinal support beams of fixed length and web-like constructions that extend between and connect the support beams. The support beams are spaced apart in a substantially equidistant manner. The web-like constructions allow the annular support frame to be radially collapsible and expandable. Each support beam preferably has a column of pre-formed openings or bores extending along a length of the support beam. The valve assembly includes three valve leaflets, wherein each leaflet has opposing side portions and each side portion is paired with an adjacent side portion of an adjacent leaflet to form a commissure. The three commissures are secured to three respective support beams with stitching that extends through the leaflets and through the pre-formed openings or bores.
