    • Objective To evaluate the clinical role of fetal echocardiography on the detection of fetus with RDH, and describe the echocardiographic characteristics of various types of RDH.
    Methods: 40 fetuses who were prenatally diagnosed as RDH by FECG were retrospectively investigated for their sonographic features.
    Results: (1) 40 fetuses were diagnosed as RDH by echocardiography. Postnatal echocardiography or clinical follow-up confirmed that 15 of them (37.5%) were normal , 9 (22.5%) were RDH complicating IUGR and ductal aneurysm, 16 (40%) were RDH complicating CHD. (2) The fetuses with RDH complicating CHD included 6 cases of CoA, 3 of anomalous pulmonary venous drainage, 2 of sinus venous type of interatrial septal defect, 2 of ventricular septal defect, 2 of persistent left superior cava associated with dilated coronaty sinus, and 1 of intertuption of aortic arch.
    Conclusion: (1) CHD, especially CoA, was often seen after birth in the fetuses with RDH. Therefore, more attention should be paid on the postnatal follow-up. (2) The severity of right heart dominance in the fetus with RDH complicating CHD was more prominent than that in the fetuses with RDH complicating IUGR and ductal aneurysm or the normal fetuses.
