Objective: To present sonographic findings in early and late appearance of fetal Ebstein's anomaly. Methods: Fetal sonography was performed in 53447 consecutive pregnant women at 14 to 16weeks' gestation. Results: Ebstein's anomaly was detected in eight fetuses, in four of them additional anomalies were observed. All eight pregnancies were terminated. In an additional fetus, a normal four-chamber view without valvular regurgitation was visualized at 15weeks' gestation. At 24weeks, a normal four-chamber view was depicted. No Doppler examination was performed at that time. The newborn was found to have Ebstein's anomaly with pulmonary stenosis. A balloon pulmonary valvuloplasty was performed with a good outcome at three months of age. Conclusion: Fetal Ebstein's anomaly may be detected in early pregnancy. The incidence is higher than what is reported in newborns. Depiction of a normal fetal heart in early and midpregnancy does not exclude the possibility of subsequent development of Ebstein's anomaly.
