[Ultrasonographically normal fetal heart]

Area of Science:

• Cardiology
• Prenatal Diagnosis
• Medical Imaging

Background:

• Systematic examination of the fetal heart is essential in routine ultrasonography.
• Accurate detection of fetal cardiac abnormalities requires thorough knowledge of fetal heart development and anatomy.
• Understanding cardiac development is key to identifying potential issues during pregnancy.

Purpose of the Study:

• To emphasize the importance of a systematic approach to fetal heart examination.
• To highlight key views and planes for assessing fetal heart anatomy and function.
• To underscore the link between fetal cardiac defects and genetic abnormalities.

Main Methods:

• Utilizing four-chamber views to assess the inflow tract of the fetal heart.
• Performing static and dynamic studies of great arteries in axial and sagittal planes for outflow tract evaluation.
• Conducting a complete morphologic study to identify all cardiac abnormalities.

Main Results:

• Specific defects like atrioventricular septal defects (ASD) are strong indicators of Down's syndrome.
• Cono-truncal anomalies are significant markers for chromosomal abnormalities.
• Certain conditions such as complete transposition and total anomalous venous connection carry high prognosis risks without prenatal diagnosis.

Conclusions:

• All identified fetal cardiac abnormalities warrant fetal karyotyping.
• Conditions like complete transposition and total anomalous venous connection require specialized attention due to prognosis.
• Complex congenital heart disease necessitates prompt cardiopediatric evaluation for management and prognosis.
