Some studies show that the use of a drug called Plaquenil may protect the baby’s heart while in the mother. The reason for this is unknown.
Mothers with SSA antibodies should have the baby’s heart checked while pregnant. A test called an echocardiogram is taken when the mother is 18,20,22,24, and 32 weeks along in her pregnancy. This test is not harmful to the baby.
