A prosthetic valve comprises a valve assembly having a base, a plurality of leaflets, and commissures. The valve also comprises a support stent having a plurality of expandable cells and a plurality of longitudinal struts. The support stent is configured to be collapsible for transluminal delivery and expandable to contact the anatomical annulus of the native valve when the prosthetic valve is positioned in situ. The support stent supports the base. The commissures of the valve assembly are secured at the longitudinal struts and adjacent one or more of the expandable cells. The longitudinal struts of the support stent further comprise a plurality of holes, and the plurality of leaflets are secured to the longitudinal struts via threads passing through the plurality of holes.
