Pulsed wave and color Doppler findings in congenital pulmonary vein stenosis.
A premature infant presented at 8 weeks of age with respiratory failure and pulmonary hypertension. Two-dimensional echocardiography was not diagnostic but color flow imaging and pulsed Doppler examination revealed turbulent and continuous pulmonary venous flow. Differing patterns of disturbed flow suggested varying severity of obstruction in individual pulmonary veins. The Doppler findings are compared to the angiographic and autopsy data.
