Describing congenital heart disease by using three-part segmental notation

Area of Science:

• Cardiology
• Radiology
• Pediatric Medicine

Background:

• Congenital heart disease (CHD) classification is crucial for diagnosis and management.
• The Van Praagh system, established nearly 50 years ago, is widely used in North America.
• Effective communication among specialists is vital for complex CHD cases.

Purpose of the Study:

• To provide a systematic approach to applying the Van Praagh classification system for CHD.
• To offer concise, step-by-step guidance for radiologists interpreting imaging studies.
• To enhance the consistent description and reporting of congenital cardiovascular abnormalities.

Main Methods:

• Utilizing the three-part Van Praagh notation: visceroatrial situs, ventricular loop orientation, and great vessel position.
• Systematic identification of morphologic atria and ventricles.
• Determining situs and loop orientation from cardiac chamber positions.
• Establishing great vessel relationships (normal, inverted, transposed, malpositioned).

Main Results:

• The Van Praagh notation offers a succinct method for describing CHD anatomy.
• The system facilitates a structured interpretation of imaging studies.
• Consistent application aids in clear reporting of congenital cardiovascular abnormalities.

Conclusions:

• The Van Praagh classification system is a well-established and valuable tool for CHD.
• Step-by-step application enhances accuracy in radiology reading rooms.
• Standardized descriptions improve communication and patient care in congenital cardiovascular medicine.
