[Fetal supraventricular tachycardia. Management]
Summary
Fetal supraventricular tachycardia (SVT) with hydrops fetalis can be diagnosed and treated using ultrasound and medications like digoxin. Transplacental therapy showed partial to total conversion in two reported cases.
Area of Science:
- Perinatology
- Fetal Cardiology
- Pharmacology
Background:
- Fetal supraventricular tachycardia (SVT) can lead to hydrops fetalis, a serious condition.
- Early diagnosis and intervention are crucial for managing fetal cardiac arrhythmias.
Observation:
- Two cases of fetal SVT with hydrops fetalis were observed.
- Ultrasound was used for diagnosis, severity assessment, and monitoring treatment response.
Findings:
- Transplacental therapy with digoxin, sotalol, and amiodarone resulted in partial to total conversion of SVT.
- Digoxin is recommended as the first-line treatment, with other agents available for refractory cases.
Implications:
- Ultrasound is a vital tool for diagnosing and managing fetal SVT and associated hydrops fetalis.
- Pharmacological management, including transplacental and direct fetal therapy, can effectively treat fetal SVT.
- This study highlights the importance of timely intervention in improving fetal outcomes for SVT.
