Diagnosis of pulmonary venous obstruction by Doppler echocardiography.

A 1 1/2-year-old female patient with atrial and ventricular septal defects and severe pulmonary arterial hypertension was found to have discrete stenosis of left upper and middle lobe pulmonary veins. The diagnosis was made by cross-sectional and Doppler echocardiography. The findings were confirmed at cardiac catheterization and operation. Pressure gradients across the pulmonary vein stenosis as obtained by Doppler echocardiography correlated well with those measured at cardiac catheterization.
