[Fetal supraventricular tachycardia. Management]

Abstract

We report two cases of fetal supraventricular tachycardia with hydrops fetalis. The transplacental therapy with digoxin, sotalol and amiodarone, using combination of both of this drugs, has given in one case a partial conversion, total in the second case. Ultrasounds allow diagnosis of SVT, evaluate the gravity when it is associated with fetal hydrops secondary to a congestive heart failure, research a cause and follow the evolution during the treatment. The treatment must begin when diagnosis of SVT is done, by digoxin; other drugs as sotalol, amiodarone or flecainide acetate are described and also direct fetal therapy by intramuscular or into the umbilical vein injections.
