In 1952, Charles A. Hufnagel implanted caged ball heart valves into ten patients (six of whom survived the operation), marking the first success in prosthetic heart valves. [citation needed] A similar valve was invented by Miles 'Lowell' Edwards and Albert Starr in 1960, commonly referred to as the Starr-Edwards silastic ball valve. [13]
Björk–Shiley valve, as depicted in patent #US003824629. The Björk–Shiley valve is a mechanical artificial heart valve.

She was a Staff Surgeon at the National Heart Institute until 1965, and then was named Deputy Chief of the Clinic of Surgery, a position she held until 1968. [7] Braunwald designed and fabricated an experimental, artificial mitral valve prostheses, implanting them in dogs at the National Heart Institute's surgical clinic in 1959.

The devices are implanted without open heart surgery. The valve delivery system is inserted in the body, the valve is positioned and then implanted inside the diseased aortic valve, and then the delivery system is removed. The catheter-based delivery system can be inserted into the body from one of several sites. [14]

A heart valve is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. A mammalian heart usually has four valves. Together, the valves determine the direction of blood flow through the heart. Heart valves are opened or closed by a difference in blood pressure on each side. [1] [2] [3]
