Twenty-Two-Year Experience with Aortic Valve Replacement: Starr-Edwards Ball Valves versus Disc Valves

Pilegaard, Hans K.

RESUMO

From 1965 through 1986, 817 patients underwent aortic valve replacement at our institution. Six hundred forty-five patients received Starr-Edwards ball valves, including 286 Silastic ball valves (Models 1200/1260), 165 cloth-covered caged-ball prostheses (Models 2300/2310/2320), and 194 track-valve prostheses (Model 2400). In contrast, 172 patients received disc-valve prostheses, including 126 St. Jude Medical aortic bi-leaflet disc valves, 32 Lillehei-Kaster pivoting disc valves, and 14 Björk-Shiley valves (6 convexoconcave and 8 monostrut).
