Six years after the first aortic valve replacement with the Starr- Edwards
Silastic ball prosthesis at Oregon Health Sciences University, the model
1260 was implanted in a 44-year-old patient at our department. During 24
years no signs of dysfunction, thromboembolism, thrombosis, periprosthetic
leaks or hemolysis were observed. Material test showed no signs of fatigue.
The dimension of the Silastic poppet was found to be one millimeter less
than the original specifications of these poppets and there were some lipid
infiltrations. Functionally the poppet was found to be nonvariant.
Histologic findings detected focal hyalinization and giant cells without
signs of acute inflammation or ulceration. With regard to its reliability
and durability, the Starr- Edwards valve prosthesis should not be viewed
with disfavor.
