Fetal Doppler echocardiographic diagnosis and successful steroid therapy of Luciani-Wenckebach phenomenon and endocardial fibroelastosis related to maternal anti-Ro and anti-La antibodies

Early prenatal detection of abnormal delay in fetal AV time conduction is possible with the Doppler superior vena cava/ascending aorta approach. Steroid therapy can cure fetal EFE and AV conduction delays associated with maternal anti-Ro and anti-La antibodies.
