First-trimester screening for congenital heart disease

Area of Science:

• Maternal-fetal medicine
• Fetal cardiology
• Prenatal diagnostics

Background:

• Advances in prenatal care technology and training have increased focus on congenital heart defect (CHD) detection.
• Current screening methods and postnatal protocols are insufficient for early CHD detection.
• First-trimester fetal evaluations are becoming more common, necessitating improved cardiac assessment methods.

Purpose of the Study:

• To establish the feasibility and effectiveness of first-trimester transvaginal heart screening for CHD detection.
• To improve the selection process for fetuses requiring further fetal echocardiography.
• To enhance prenatal management strategies for pregnancies complicated by CHD.

Main Methods:

• Utilizing advanced ultrasound equipment for visualization of the fetal circulatory system.
• Implementing transvaginal screening in the first trimester (12-13 weeks of gestation).
• Focusing on otherwise uncomplicated pregnancies to identify those with potential CHD.

Main Results:

• Excellent visualization of the fetal circulatory system is achievable at 12-13 weeks of gestation.
• First-trimester transvaginal heart screening is demonstrated to be feasible and well-tolerated.
• Technological advancements facilitate early and detailed assessment of fetal cardiac structures.

Conclusions:

• Improved first-trimester fetal heart screening is expected to significantly increase CHD detection rates.
• Enhanced prenatal detection will lead to better management of these patients during gestation.
• Early identification facilitates timely intervention and preparation for necessary cardiac surgery.
