We present the case of an infant with prenatal diagnosis, at 32 weeks gestation, of Ebstein’s anomaly without anterograde flow from right ventricular to pulmonary atresia (PA)—functional PA with flow reversal in the ductus arteriosus. Prostaglandin E1 was started after birth. Chest X-ray showed severe cardiomegaly and echocardiogram confirmed Ebstein’s anomaly with a thickened non-opening pulmonary valve without anterograde flow but with mild regurgitation. Multidisciplinary team decision was to progressively reduce prostaglandins and have an expectant attitude. Peripheral oxygen saturation above 85% was maintained and serial echocardiograms documented progressive reduction of the ductus arteriosus and the opening of the pulmonic valve cusps, with the development of anterograde flow. The newborn was discharged at day 19 of life without the need for any intervention, and at last follow-up remains asymptomatic, with anterograde normal flow in the pulmonary valve.
