[The Doppler-echocardiography in the study of transvalvular pulmonary flow (author's transl)].
The AA. studied 96 subjects: 74 normals, 15 patients with pulmonary stenosis, 6 with pulmonary regurgitation and 1 with combined stenosis and pulmonary regurgitation, by using pulsed Doppler echocardiography. This technique, which supplements M-mode echocardiography with Doppler flow detection, allowed determination of direction and quality--laminar or turbolent--of flow through pulmonary valve. In our experience, pulsed Doppler echocardiography is a sensitive and specific method for detection of pulmonary stenosis and regurgitation and extends ultrasound diagnosis beyond the capabilities of M-mode echocardiography.
