Sclerosis of the Chordae Tendineae of the Mitral Valve

Thickening and sclerosis of the chordae tendineae of the mitral valve are seen fairly frequently in hearts that are not ordinarily considered to be rheumatic. In this report a systematic study of these lesions is presented. Factors involved in their pathogenesis and their significance in the development of the chronic rheumatic deformity are discussed.
