Echocardiography accurately identifies atrioventricular septal defects, correlating well with anatomical findings in specimen hearts. This study confirms echocardiography
Area of Science:
- Cardiovascular Anatomy
- Pediatric Cardiology
- Diagnostic Imaging
Background:
- Atrioventricular septal defects (AVSD) are complex congenital heart anomalies.
- Accurate anatomical assessment is crucial for diagnosis and surgical planning.
- Echocardiography is a primary non-invasive imaging modality for congenital heart disease.
Purpose of the Study:
- To correlate the detailed anatomical features of atrioventricular septal defects with echocardiographic findings.
- To establish the diagnostic precision of echocardiography in characterizing AVSD subtypes and associated anomalies.
Main Methods:
- Sixty human specimen hearts underwent sequential segmental analysis.
- Echocardiograms were performed on 34 patients diagnosed with AVSD.
- Anatomical specimens with echocardiographic equivalents were selected for direct correlation.
Main Results:
- Specimen hearts showed various situs anomalies (solitus, dextroisomerism, inversus, levoisomerism) and valve arrangements (common or two AV valves).
- Rastelli classifications (A, B, C, intermediate, mixed) were determined in both specimens and echocardiograms.
- Associated anomalies like pulmonary stenosis, atresia, ASD, PDA, and anomalous pulmonary venous connection were identified in both groups.
Conclusions:
- Anatomical-echocardiographic correlation demonstrated a high degree of diagnostic precision.
- Echocardiography is a reliable tool for characterizing the complex anatomy of atrioventricular septal defects.
