[The echocardiogram in mitral anulus calcification].

In agreement with the known high incidence of mitral anulus calcification in elderly patients, the authors have found corresponding calcifications in echocardiographic examinations in 61 patients as the single or additional cause of an abnormal systolic or diastolic murmur. The intracardiac calcifications were known of from the chest X-ray only in 6 patients. The echocardiograms served to locate and estimate the amount of the calcification. Calcifications of the aortic cusps, found in 75% of patients, may be of degenerative origin. The echocardiographic presentation of the degenerative calcifications can be misinterpreted either as postrheumatic valvular disease, posterior pericardial effusion or hypertrophic cardiomyopathy. Registration by continuous sector scan was necessary to differentiate these entities.
