[Intracardiac phonocardiography in young persons with congenital heart defects].

Thirty nine persons 17 to 22 years old with mild forms of an interatrial defect, stenosis and congential dilation of the pulmonary artery were examined. During catheterization of the right heart intracardiac phonocardiography and characteristic systolic murmurs in the pulmonary artery and in the right ventricle were recorded, all this being of help in precisely diagnosing these minor and, therefore, atypical clinical forms of the malady.
