Abstract
A tissue heart valve has a cloth-covered stent which provides several layers of padding over the stent edges and an integral sewing ring while maximizing the internal valve diameter for a given size heart annulus. No edges of the cloth are exposed. A continuation of the pledget covers all knots of the stitches connecting the tissue to the stent.
