“…It was observed that adsorption of fibrinogen is (i) less on polished glass compared to polished Stellite-21, (it) the amount of fibrinogen adsorbed on to polished Stellite-21 is dependent on polishing characteristics of the surfaces, and (iii) Teflon-coated Stellite-21 surfaces adsorb more fibrinogen (Fig. 7) (49).…”

In vitro methods have been developed over the last several years to predict the implantation behavior of cardiovascular prostheses. With metals and alloys, their spontaneous potentials in blood or physiological saline, the corrosion behavior in sodium chloride, and surface cleanliness are factors that determine the in vivo patency in animals and humans. The materials used for cardiac valves have a wide passivation region. In vivo monitoring of cardiac prostheses indicates an anodic shift of their rest potentials. Surface contamination appears to cause premature thrombosis and occlusion of cardiac valves.

“…Recently adsorption of fibrinogen on Stellite-21 has been studied using radioactively labeled fibrinogen (49). The results are of particular relevance in the design and manufacture of cardiac valves.…”
