La Commissurotomie Mitrale "à cœur fermé"

• Sir Henry Souttar : 1925, dilatation au doigt

• C.P. Bailey en 1948 effectue plusieurs

dilatations mitrales, qu’il nomme "commissurotomies". Il est suivi par Harken et Brock.

Björk-Shiley Tilting Disc Valves Donald P. Shiley, an engineer in Santa Ana, CA with a

garage Late 1960’s began developing heart valves Viking O. Björk, a Swedish heart surgeon came on board

a few years later

Radial-spherical (R/S) valve introduced in 1974. Subjected to several design changes. Flat occluder disc, originally of Delrin, later changed to pyrolytic carbon. Stellite housing. Opens to 50-60 degrees. Inlet and outlet struts are welded to the flange. Early failures of the inlet strut welds were eliminated with a change to the welding process.

Björk-Shiley Convexo-Concave valve: The Good News

C/C disc improves hemodynamics—decreased complications due to thromboembolism (TE)

Received FDA approval in 6 months Became the most popular valve in the

world (ultimately represented half of all valves implanted)
