ABSTRACT
Early delivery, immediate ventricular pacing, and inotropic support have failed to improve the outcome of hydropic fetuses with congenital complete atrioventricular block. On detection of hydrops, two fetuses were treated with maternally administered digoxin and furosemide with prompt and sustained resolution of intrathoracic fluid accumulations. Clearance of serosal fluid collections may prevent pulmonary hypoplasia and improve cardiac function. Before proceeding with premature delivery in such patients, a brief trial of transplacental anticongestive therapy is indicated.
