Abstract: We report the intrauterine treatment of a case of fetal persistent supraventricular tachycardia complicated by heart failure. The ultrasound findings at 32 +1 weeks of gestation showed fetal tachycardia of 242 beats/min, fetal generalized edema, ascites, and visible pulsation spectrum in the intra-abdominal segment of the umbilical vein. Fetal cardiac arrhythmia persisted after maternal oral digoxin for 46 hours. In view of the continuous deterioration of the fetal condition with the persistent umbilical vein pulsation spectrum and worsening edema, fetal intramuscular injection of cedilanid under ultrasound guidance was performed, resulting in successful cardioversion. The pregnant woman gave birth to a baby girl by cesarean section due to premature rupture of membranes and oligohydramnios at 34 +6 weeks of gestation, with normal functions of heart and other organs. During a follow-up to 8 months, no obvious abnormalities were found.
