A guide to the radiographic identification of prosthetic heart valves: an addendum.
Several years ago "A Guide to the Radiographic Identification of Prosthetic Heart Valves" (Circulation 57:613, 1978) described the radiographic silhouettes of 40 different cardiac prosthesis in clinical use. Since that time a number of prostheses have been developed and introduced to clinical practice. Ten of these newer prostheses manufactured by six domestic companies were photographed and radiographed as they would be expected to appear in standard chest radiographs. The radiographic silhouettes are described and distinguishing features are discussed.
