Fetal atrial flutter is a lethal tachyarrhythmia with a 10% mortality rate. Diagnosis is made with echocardiography, and management should be multidisciplinary with obstetricians, fetal cardiologists, and specialist neonatologists.

Fetal Atrial flutter (AF) is an uncommon condition accounting for about 30% of all fetal tachyarrhythmias. It is associated with structural heart anomalies and hydrops, with 10% fetal mortality rate. This case demonstrates a successfully managed atrial flutter at term with postnatal electrocardioversion using multidisciplinary team approach.
