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.
为便于通过射线照相识别人工心脏瓣膜，对各种主动脉瓣、二尖瓣和三尖瓣人工瓣膜的射线照相轮廓进行了分析并制成示意图。从国内七家制造商处获得了40种不同的人工瓣膜模型（异种移植瓣膜和机械瓣膜）。将每个假体放置在接近主动脉瓣、二尖瓣或三尖瓣瓣环平面的位置。然后对瓣膜进行射线照相和拍照，就像它们在胸部后前位和左侧位X线片上的样子。检查射线照相轮廓，并设计了一种方案，以便能够轻松而准确地区分众多心脏瓣膜假体。文中展示了各种瓣膜类型在常规胸部X线片上的样子。
