Research Facts
The first artificial heart valve, an acrylic ball valve, was used in 1952. Several forms of the ball valve were created and used in valvular replacement, but were phased out starting in 1965 when the first disk valve was created by Kay & Donald Shiley. One of the final versions of the ball valve was the Smeloff-Cutter valve, which was constructed of a commercially pure titanium cage in a bare, uncoated nature. This cage had a non overlapping, full-orifice with a ball constructed of silicone rubber. The design of this valve permitted slight regurgitation of blood that would in effect, wash the ball and cage, preventing thrombosis. The Smelter-Cutter valve enjoyed over a decade of success in valvular replacement with an established record of durability. Research information in donor file.
