Critical Ebstein's anomaly with circular shunt: from successful fetal therapy with non-steroidal anti-inflammatory drugs to biventricular repair using Da Silva cone technique.

We report an innovative treatment strategy for fetal Ebstein's anomaly with a circular shunt. We used transplacental non-steroidal anti-inflammatory drugs, at the 29th gestational week, to constrict the ductus arteriosus avoiding fetal demise. We addressed the critical neonate with an urgent Starnes procedure. Finally, instead of following the usual single-ventricle palliation pathway after the Starnes procedure, we achieved successful two-ventricle repair with the cone technique at 5 month old.
