Purpose To assess the spectrum of associated anomalies, the intrauterine course, the outcome and possible prognostic markers in prenatally diagnosed Ebstein’s anomaly (EA). Materials and Methods All cases of EA diagnosed over a period of 13 years with a minimum follow-up of 1 year were retrospectively collected in 4 tertiary referral centers in Germany. Results In the study period 76 cases of EA were prenatally diagnosed. The mean gestational age at diagnosis was 25.0 weeks (range: 13 – 35). 41 (53.9 %) cases were isolated and 35 (46.1 %) had other cardiac and/or extracardiac anomalies. 19 (25.0 %) pregnant women opted for termination of pregnancy, intrauterine fetal death occurred in 7 cases (9.2 %), neonatal death in 14 cases (18.4 %), death in infancy or childhood in 9 cases (11.8 %) and 27 children (35.5 %) were alive at the last follow-up. After exclusion of terminations, the only parameter inversely correlated with intrauterine survival was hydrops fetalis. Prognostic parameters significantly associated with postnatal non-survival were an abnormal Celermajer index (right atrium/heart ratio > 0.7), cardiomegaly (cardiothoracic circumference ratio > 0.5), absence of antegrade flow over the pulmonary valve and earlier diagnosis in pregnancy. Conclusion Prenatally diagnosed EA has a high morbidity and mortality with the highest loss rate in the intrauterine and neonatal period. In our study, hydrops fetalis was the only parameter significantly associated with intrauterine demise, while other prenatal markers were only significantly associated with postnatal mortality.
