1. A prosthetic heart valve comprising:
a stent frame comprising a base comprising at least two stent posts extending upwardly, a first upper frame portion, a second upper frame portion, and a third upper frame portion connected on top of the at least two stent posts via stent frame extensions,
wherein the first upper frame portion has a shape mimicking that of an upper edge of and between the at least two stent posts of the base, a lower edge of the second upper frame portion has a shape that is similar to an upper edge of the first upper frame portion, and a lower edge of the third upper frame portion has a shape that is similar to an upper edge of the second upper frame portion, and
wherein the first upper frame portion connects to the at least two stent posts only at each of top points of the at least two stent posts by the stent frame extensions, the second upper frame portion connects to the first upper frame portion only at each of top points of the first upper frame portion by the stent frame extensions, and the third upper frame portion connects to the second upper frame portion only at each of top points of the second upper frame portion by the stent frame extensions; and
a leaflet material having an upper portion with at least two arches extending upwardly therefrom and
the leaflet material is secured to the stent frame by having the leaflet material weaving through the stent frame between the upper edge of the at least two stent posts of the base and the first upper frame portion, between the first and the second upper frame portions, and between the second and the third upper frame portions.
