[Chordal rupture syndrome of the mitral valve].

Fifty-eight patients with chordal ruptures of the mitral valve were examined. The main echocardiographic signs of chordal ruptures of the anterior and posterior mitral cusp were described. The authors provide the results of the use of two-dimensional echocardiography for diagnosing chordal ruptures of the mitral valve depending on the etiological factor of chordal pathology (mesenchymal abnormalities, rheumatic fever, infective endocarditis, coronary heart disease).
