To facilitate the radiographic identification of prosthetic heart valves,
radiographic silhouettes of various aortic, mitral and tricuspid valve
prostheses were analyzed and shematized. Forty different prosthetic valve
models (heterograft and mechanical) were obtained from seven domestic
manufacturers. Each prosthesis was positioned to approximate the aortic,
mitral or tricuspid valve anulus plane. The valves were then radiographed
and photographed as they would appear in posteronanterior and left lateral
chest radiographs. The radiographic silhouettes were examined and a scheme
was designed to enable easy, yet accurate, differentiation of the many
heart valve prostheses. Illustrations of the various valve types are
presented as they would appear in routine chest radiographs.
