Abstract
Cloth-covered Starr-Edwards caged ball valves implanted in the aortic and mitral valve positions for 39 years were extracted. Both showed valve dysfunction resulting from pannus overgrowth. The metal cages of the Starr-Edwards valves were covered with worn cloth. This case indicates the extended durability of Starr-Edwards valves and the importance of the design and materials of prosthetic heart valves to avoid pannus overgrowth and prosthetic valve abrasion.
