Pulsed Doppler echocardiography was used to examine the relation between pulmonary valve motion and pulmonary artery (PA) flow velocity patterns in 39 adults. In 16 patients with normal PA pressure (mean pressure less than 20 mm Hg), PA flow velocity accelerated slowly to a peak flow velocity at mid...
