Segmental analysis of congenital heart disease: putting the "puzzle" together with computed tomography

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Surgical and medical advancements have increased life expectancy for patients with congenital heart disease (CHD).
• This has led to a greater reliance on cross-sectional imaging modalities for diagnosing and managing complex CHD.
• Accurate interpretation of imaging is crucial for effective patient care.

Purpose of the Study:

• To describe a morphological and sequential segmental approach for interpreting complex congenital heart defects on cross-sectional imaging, primarily computed tomography (CT).
• To provide a systematic method for understanding the complex anatomy of CHD.
• To enhance diagnostic accuracy and facilitate clear communication in CHD management.

Main Methods:

• Review of cross-sectional imaging techniques, focusing on computed tomography (CT).
• Application of a morphological and sequential segmental analysis framework.
• Detailed examination of cardiac structure relationships and differentiation of transposition types.

Main Results:

• The manuscript outlines a systematic approach to deciphering complex CHD on CT scans.
• It details methods for differentiating various types of transposition.
• It emphasizes understanding the anatomic relationships of cardiac structures for accurate CHD description.

Conclusions:

• A morphological and sequential segmental approach provides a robust framework for interpreting complex congenital heart disease on cross-sectional imaging.
• This method aids in accurate diagnosis, classification, and communication of CHD findings.
• Enhanced understanding of cardiac anatomy through imaging improves management strategies for adult congenital heart disease.
