Abstract:
We report for the first time a fetal case with sustained regression from isolated complete to first-degree heart block on transplacental treatment with high-dose dexamethasone. Doppler echocardiography is an excellent diagnostic tool in the non-invasive assessment of fetal atrioventricular conduction and its anomalies.
