[Morphopathologic study of total anomalous pulmonary venous connection]

Area of Science:

• Cardiovascular Anatomy
• Congenital Heart Disease Research
• Medical Imaging Analysis

Context:

• The study investigates morphological variations in pulmonary venous connections.
• Utilizes the segmental sequential system for detailed cardiac analysis.
• Employs Darling's classification for categorizing anomalous connections.

Purpose:

• To determine the morphological features of anomalous pulmonary venous connections.
• To ascertain the frequency of different types of anomalous pulmonary venous connections.
• To identify associated cardiac anomalies and malformations.

Summary:

• Analyzed 106 hearts, detailing atrial situs (solitus, dextroisomerism, inversus) and pulmonary venous connection sites (supracardiac, cardiac, infradiaphragmatic).
• Found 100 hearts with atrial septal defects and 6 with patent foramen ovale; 14 specimens exhibited obstructed venous collectors.
• Dextroisomerism cases frequently presented with intracardiac malformations.

Impact:

• Highlights the importance of anomalous connection site, atrial septal defect size, and venous collector obstruction in diagnosis.
• Provides valuable insights for understanding the pathophysiology of these anomalies.
• Aids surgeons in selecting optimal surgical strategies for complex congenital heart defects.
