Ruptured Mitral Chordae Tendineae

Abstract

The present study presents pertinent clinical and pathologic findings in 20 cases of ruptured mitral chordae tendineae encountered at the Mayo Clinic between 1934 and 1958 inclusive. Mitral insufficiency results from the rupture of chordae tendineae, the severity being related to the number of chordae ruptured. The resulting heart disease may be severe and may progress to cardiac decompensation and death. Bacterial endocarditis was the major etiologic factor in rupture of the chordae tendineae in this study.
