[Echocardiographic study of the heart in children with mitral valve prolapse and connective tissue dysplasia].

Altogether 125 children with connective tissue dysplasia and mitral valve prolapse were subjected to clinical and echographic examinations. Dilation of the aortic root, elevation of pulmonary artery pressure and derangement of myocardial contractility were discovered. These disorders occurred as a result of disseminated connective tissue abnormalities.
