Failure of Beal mitral valve prosthesis. Clinical and radiographic features
RG Jost, RC McKnight and CL Roper
This report presents a case of severe dysfunction of an improved Model 104
Beall valve secondary to disc wear. This type of valve failure may be
extremely difficult to detect by auscultation, echocardiography, or
fluoroscopic examination. Prosthesis failure with resulting mitral
insufficiency should be considered in any patient with a Teflon disc Beall
mitral valve in whom there is unexplained clinical deterioration.
