The usefulness of the phonocardiography in the diagnosis of the extrinsic obstruction of the pulmonary artery. Report of a case (author's transl).
The Authors describe a case in which an anterior mediastinal tumor manifested as a cardiovascular disease. Phonocardiographic findings and their modifications induced by respiratory manoeuvres are presented and discussed. Particular enphasis is given to the disappearance, with deep inspiration, of the pulmonary ejection murmur associated with the simultaneous paradoxical behaviour of pulmonary component of the second sound. The Authors suggest that such findings can be indicative of pulmonary outflow obstruction by an external mass.
