Abstract
Prosthetic heart valves comprising an annular, right cylindrical, metal stent covered with fabric to which a glutaraldehyde-stabilized pericardial valving element formed of three leaflets, each having a plateau on a truncated triangle extending higher at the center than at the edges, and formed as a cylinder having a diameter substantially equal to the diameter of the stent, and having a low profile is disclosed.
