Fetal cardiac screening: 1st trimester and beyond

Area of Science:

• Cardiology
• Prenatal Medicine
• Pediatrics

Background:

• Congenital heart defects (CHD) are the most common birth defect and a leading cause of infant mortality.
• CHD can occur in low-risk pregnancies, highlighting the need for universal screening.
• Prenatal diagnosis of CHD is crucial for informed decision-making and optimal perinatal management.

Purpose of the Study:

• To review current practices and advancements in fetal cardiac screening throughout pregnancy.
• To emphasize the importance of routine screening in all pregnant patients.
• To discuss the evolving trend of first-trimester screening for high-risk populations.

Main Methods:

• Review of updated fetal cardiac screening guidelines.
• Discussion of technological advancements in prenatal imaging.
• Analysis of educational efforts to improve CHD detection rates.

Main Results:

• Updated guidelines and technology have increased prenatal detection of CHD in both low- and high-risk groups.
• Prenatal diagnosis has demonstrably improved neonatal and infant outcomes.
• First-trimester screening is emerging for specific high-risk groups.

Conclusions:

• Routine fetal cardiac screening is vital for early detection and management of CHD.
• Continued advancements and expanded screening protocols are expected to further improve outcomes.
• Prenatal diagnosis of CHD significantly benefits affected infants and families.
