A prosthetic heart valve (10) includes an expandable stent (18) and a leaflet assembly (16) coupled to the expandable stent. The expandable stent is radially expandable from a first size for intraluminal delivery through a body passageway to a second size for implantation of the prosthetic heart valve in the body passageway. The leaflet assembly includes leaflets (30a, 30b, 30c)movable between an open position permitting flow past the expanded stent and a closed position substantially restricting flow past the expanded stent. Each of the leaflets is coaptable with each of the other leaflets in the closed position to define a coaptation region (24) of about 15 percent to about 35 percent of the overall height of each of the plurality of leaflets.
