[Observations of the mitral valve prolapse syndrome. 14 cases of inheritance of the syndrome].

The author, for a short period of several months, found 129 cases with the syndrome of mitral valve prolapse. A case is described with a combination of the syndrome with congenital complicated cardiopathy: pulmonary arterial stenosis, interventricular defect and persisting arteriarl low. A considerable part of the patients had dysplastic growth anomalies. In 13, out of the 14 inquired families, the syndrome was found simultaneously in the father or mother and the child. The significance of the hereditary anomaly of the connective tissue in the syndrome genesis is emphasized.
