Late Failure of Prosthetic Heart Valve
A 20-year-old woman developed late thrombosis of a 22 mm Lillehei-Kaster mitral valve prosthesis. Despite adequate anticoagulation measures, clinical detection of significant dysfunction of this particular prosthesis is difficult because of the absence of distinctive opening and closing sounds and the radiolucent character of the disc. Early diagnostic catheterization may be warranted.
