The impact of treatment of the fetus by maternal therapy on the fetal and postnatal outcomes for fetuses diagnosed with isolated complete atrioventricular block.

Objectives: to analyse retrospectively the data of fetuses diagnosed with isolated complete atrioventricular block and efficacy of treatment of the fetus by maternal therapy.

Materials: Between 1992 and 2004, we diagnosed complete atrioventricular block in 26 singleton and 2 twins fetuses of 27 pregnant women known to have anti Ro/La antibodies, 11 with autoimmune disease, one patient analysed in 2 pregnancies. At presentation, 20 of the fetuses were compensated and non-hydropic, while 8 had hydrops.

Pregnancy and autoimmunity: maternal treatment and maternal disease influence on pregnancy outcome.

If a woman suffers from autoimmune disease (AD), several factors can affect pregnancy or neonatal outcome: repeated spontaneous pregnancy losses (frequently related to antiphospholipid antibodies (aPL)), neonatal lupus with complete congenital heart block (CHB) (linked to transplacental passage of IgG anti Ro/SS-A antibodies) and the disease activity itself that can affect the mother, the pregnancy and fetal outcome. If appropriately managed, the antiphospholipid syndrome (APS) is "one of the few tractable causes of pregnancy losses." A recent case control study, on babies from APS-mothers and healthy mothers, did not show any difference in the occurrence of neonatal complications.
