Fetal echocardiography is a valuable tool for diagnosing heart defects in multiple gestations. This study confirms its utility in identifying fetal cardiac anomalies and guiding management in twins and triplets.

Area of Science:

Maternal-Fetal Medicine
Pediatric Cardiology
Prenatal Diagnosis

Background:

Multiple gestations present unique challenges in prenatal diagnosis.
Fetal cardiac anomalies can impact pregnancy management and neonatal outcomes.

Purpose of the Study:

To evaluate the feasibility and utility of fetal echocardiography in multiple gestations.
To determine the diagnostic yield of fetal echocardiography for cardiac defects in high-risk multiple pregnancies.

Main Methods:

Retrospective review of fetal echocardiograms from 36 multiple gestations (twins and triplets).
Analysis of referral indications, including suspected cardiac anomalies, extracardiac malformations, and karyotypic abnormalities.
Correlation of findings with postnatal diagnoses and outcomes.

Related Experiment Videos

Main Results:

11 fetal cardiac defects were detected in 10 pregnancies.
Cardiac defects were confirmed in fetuses referred for suspected anomalies, extracardiac malformations, and karyotypic abnormalities.
Interventions, including delivery planning and maternal treatment for fetal heart failure, were implemented in six cases.

Conclusions:

Fetal echocardiography is a feasible and useful diagnostic tool in selected multiple gestations.
The information obtained from fetal echocardiography aids in clinical management and decision-making.
Prenatal diagnosis of fetal cardiac defects in multiple pregnancies, while complex, can significantly influence patient care.
