[The clinical significance of the audible and mechanographic manifestations of mitral valve prolapse].

Graphic techniques were employed to examine 82 patients with mitral valve prolapse verified on echocardiography. In addition to the known acoustic symptoms, enhancement of tones III, IV and V was identified, especially in transmitral regurgitation, together with inverted alternating of the components of tones I and II. Mitral click (OS) was discovered in one third of the examined.

[Changes in blood pressure in the pulmonary artery in myocardial infarct].

A polygraphic study involved 122 patients with acute myocardial infarction mostly of transmural nature. In 42 cases using parallel catheterization, barograms of the right portion of the heart and pulmonary artery were recorded. The above non-invasive techniques were tested in relation to their suitability for the indirect determination of the pulmonary circulation pressure.

[Results of focused and projector ultrasonic Doppler cardiovalvulography (a study of patients with pulmonary normo- and hypertension)].

A comparative study of the results of Doppler cardiovalvulography using standard (projector) and original focused ultrasound source is reported. Patients with mitral stenosis is reported. Patients with mitral stenosis and normal or elevated pulmonary pressure were investigated.
