Key result
Maternal administration of oral flecainide successfully normalized fetal heart rate to 120-130 bpm and resolved early hydrops fetalis in a fetus with supraventricular tachycardia.
Why the study?
Fetal arrhythmia can lead to hydrops fetalis and fetal heart failure if untreated.
Does maternal administration of flecainide resolve fetal SVT and early hydrops fetalis?

Does maternal administration of flecainide resolve fetal SVT and early hydrops fetalis?
Maternal administration of flecainide successfully treated fetal SVT complicated by early hydrops fetalis, leading to the delivery of a healthy infant.
Faridpour et al. (2026) conducted a case report in Fetal Supraventricular Tachycardia (n=1). Flecainide was evaluated on Fetal heart rate normalization and hydrops resolution. Maternal administration of oral flecainide successfully normalized fetal heart rate to 120-130 bpm and resolved early hydrops fetalis in a fetus with supraventricular tachycardia.
