[Doppler echocardiography in the diagnosis of tricuspid anomalies (author's transl)].

Doppler echocardiography has been applied in a study of the tricuspid and central venous blood velocity curves in a number of cases, including eleven cases of insufficiency, six cases of stenosis, five cases of steno-insufficiency of the tricuspid valve and one case of Ebstein's disease. The tracings were compared to normal reports and to those appartaining to a few patients with right ventricular failure from different causes. For six patients the venous blood velocity curve was recorded contemporaneously with the right atrioventricular pressure curves. Doppler echocardiography has proved that it can offer useful indications on tricuspid anomalies. The analysis of the central venous and tricuspid blood velocity curve allows us to detect hemodynamic alterations characteristic of this valvular disease.
