Endocardial fibroelastosis after replacement of mitral valves with tilting disk prostheses. A report of two cases.
Left ventricular endocardial fibroelastosis developed in two patients whose mitral valves were replaced by tilting disk prostheses. The distribution of the lesions was compatible with their being caused by a hemodynamic effect of the prosthetic valves. The fibroelastosis appeared to have been of no clinical importance in one patient, but in the other, the endocardial thickening was greater and was probably a factor in causing cardiac decompensation.
