[The role of abnormally located chordae in the origin of accidental heart murmurs in children].

A study of 55 children with accidental systolic and diastolic heart murmurs demonstrated that abnormal chorda position (ACP), detected at echocardiography in various heart cavities, was the principal contributing factor. The relationship between the intensity and other parameters of systolic murmurs and abnormal chorda topography is discussed. Abnormal position of the chordae was not associated with any deviations from basic morphometric characteristics of the heart and should therefore be regarded as a normal variant.
