Summary
This study proposes a unified classification for ventricular septal defects (VSD), integrating morphology, location, and surgical aspects. The findings establish a standardized approach for diagnosing and understanding these complex congenital heart conditions.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Anatomical Pathology
Context:
- Existing classifications for ventricular septal defects (VSD) lack a unified approach.
- Varied terminology complicates communication and surgical planning for VSD.
- A standardized classification is needed for morphological, topographical, and surgical criteria.
Purpose:
- To establish a common terminology and classification for VSD.
- To integrate morphologic, topographic, and surgical criteria for VSD.
- To provide a basis for precise interpretation of diagnostic imaging in VSD.
Summary:
- One hundred and one VSD cases were analyzed using a sequential segmental approach.
- The ventricular septum was divided into four areas: inlet, trabecular, outlet, and perimembranous.
- Perimembranous VSD constituted 77.23%, with detailed subtypes based on muscular extensions and relationships to cardiac valves and conduction tissue.
Impact:
- The proposed topographic-structural classification aids in precise VSD localization and characterization.
- Understanding VSD surgical anatomy improves diagnostic imaging interpretation.
- This classification provides a foundation for improved surgical strategies and patient outcomes in congenital heart disease.
