Abstract:

Ebstein anomaly is a rare congenital cardiac abnormality with various associated intra-cardiac anomalies, which accounts for 1 percent of all congenital cardiac anomalies. Severe tricuspid regurgitation, pulmonary stenosis/hypoplasia, the decreased ratio of pulmonary, aorta diameter and pleural effusion/ascites/pericardial effusion are common in fetuses with Ebstein anomaly. Fetal echocardigraphy plays a key role in the detailed diagnosis and prognosis evaluation. Fetal Ebstein anomaly may be found in early pregnancy. The incidence is higher than what is reported in newborns. However, depiction of a normal fetal heart in early pregnancy and midpregnancy does not exclude the possibility of subsequent development of Ebstein anomaly. This article describes a fetal Ebstein anomaly diagnosed at 23 weeks of gestation. There was significant cardiomegaly and severe tricuspid regurgitation in this case. This case report provides us a comprehensive overview of fetal Ebstein′s anomaly.
