BACKGROUND
Complete atrioventricular block (CAVB) is rarely seen, as it occurs in only 1:11 000 to 1:20 000 newborns. There is a serious risk of mortality in CAVB, mainly in those cases associated with hydrops, fetal cardiac frequency ≤ 55 beats/minute, and premature delivery.
METHODS
Case of complete atrioventricular block with a poor prognosis (hydrops fetalis and foetal cardiac frequency < 5 beats/minute) caused by anti-La and anti-Ro antibodies. Intrauterine symptoms improved after treatment with terbutaline, permit- ting foetal viability and successful postnatal treatment with a cardiac pacemaker.
CONCLUSIONS
In case of complete atrioventricular block of cause autoimmune with poor prognosis should be treated with positive inotropic drugs, anticholinergics or b-mimetic in the attempt to maintain adequate ventricular frequency, and thus prevent hydrops fetalis from occurring.
