Impact of fetal echocardiography

Area of Science:

• Cardiology
• Prenatal Medicine
• Medical Imaging

Background:

• Prenatal diagnosis of congenital heart disease (CHD) is a well-established practice.
• Fetal life diagnosis identifies cardiac lesions and associated abnormalities, aiding prognosis discussions.

Purpose of the Study:

• To highlight the importance of prenatal diagnosis for congenital heart disease.
• To emphasize the benefits of early detection for optimizing postnatal outcomes.
• To inform screening policies and training for obstetric anomaly scans.

Main Methods:

• Review of established prenatal diagnostic techniques for cardiac anomalies.
• Inclusion of the four-chamber view and outflow tract views in mid-trimester anomaly scans.
• Consideration of newer screening techniques like nuchal translucency measurement.

Main Results:

• Antenatal diagnosis has been linked to reduced morbidity and mortality for conditions like coarctation of the aorta, hypoplastic left heart syndrome, and transposition of the great arteries.
• Most fetuses with CHD are identified within the 'low risk' population, underscoring the need for universal screening.
• Improved diagnostic yield through standardized cardiac views in anomaly scans.

Conclusions:

• Prenatal diagnosis of CHD significantly improves outcomes for affected newborns.
• Enhanced training for obstetric sonographers and standardized cardiac screening protocols are essential.
• Integrating advanced screening methods can identify high-risk fetuses for timely cardiac assessment.
