A method of making a prosthetic heart valve may include providing an annular stent having a plurality of annularly spaced commissure portions having tips, covering each of the tips with a first fabric cover, covering the first fabric covers and the remainder of the stent with a second fabric cover, covering the second fabric cover with a first tissue membrane, and covering the outside of the first tissue membrane with a second tissue membrane, the second tissue membrane forming leaflet portions that extend inwardly between the commissure portions.
