摘要：

We report two cases of fetal left heart hypoplasia with extremes of si e of interatrial communication, i.e. a closed foramen ovale and an atrial septal defect. Doppler examinations of the pulmonary veins showed almost to and fro flow in the fetus with the closed foramen ovale and, in contrast, a normal flow velocity waveform in the fetus with the atrial septal defect, despite mitral atresia. Our observations support the importance of left atrial pressure in the creation of a pulmonary venous flow pattern in the fetus.
