1. A prosthetic valve, comprising:
a plurality of leaflets, wherein each leaflet includes a central region and two side regions on opposite sides of the central region, wherein the central region has a shape substantially that of an isosceles triangle and is defined by two central region sides, a leaflet base, and a leaflet free edge, wherein the two central region sides converge from the leaflet base toward the leaflet free edge, and wherein each of the two side regions has a shape substantially that of a triangle and is defined by one of the central region sides, one of first or second leaflet sides, and the leaflet free edge, wherein the leaflet base comprises a linear portion; and
a frame having a plurality of spaced apart leaflet frame elements defining a plurality of leaflet windows, wherein each leaflet window comprises a leaflet window base and first and second leaflet window sides that diverge from the leaflet window base;
wherein one of the leaflets is located within each of the windows, wherein the first leaflet side is coupled along its length to the first leaflet window side and the second leaflet side is coupled along its length to the second leaflet window side, and wherein the leaflet base is coupled along its length to the leaflet window base.
