FLECAINIDE AGAINST FETAL SUPRAVENTRICULAR TACHYCARDIA COMPLICATED BY HYDROPS-FETALIS

Fetal supraventricular tachycardia (SVT) associated with cardiac failu re, confronts the physician with an increased risk of fetal demise, pr emature labor and difficult neonatal management, with a high newborn m orbidity and mortality (1). Successful restoration of sinus rhythm by administration of antiarrhythmic drugs to the mother has been describe d (2). However, questions about effectiveness have since been raised w ith these drugs, especially in hydropic fetuses. An efficient, powerfu l and rapid treatment should then be warranted for such cases, and we propose to introduce flecainide acetate as first line drug.
