Summary
This report details a rare case of common arterial trunk with an atrioventricular septal defect in an infant. A unique finding was the intact atrial septum within the atrioventricular septal defect.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Medical Case Reports
Background:
- Common arterial trunk (CAT) is a rare congenital heart defect where a single vessel arises from the ventricles.
- Atrioventricular septal defects (ASDs) involve abnormal development of the cardiac septa and valves.
- The co-occurrence of CAT and ASD is exceptionally uncommon.
Observation:
- A 5-month-old infant presented with complex congenital heart abnormalities.
- Clinical, echocardiographic, electrocardiographic, and angiographic evaluations were performed.
- Autopsy findings provided detailed anatomical information.
Findings:
- The infant had common arterial trunk associated with an atrioventricular septal defect.
- This specific combination represents the 13th reported case in medical literature.
- A notable and unusual feature was an intact atrial component within the atrioventricular septal defect.
Implications:
- This case expands the understanding of rare congenital heart defect presentations.
- Highlights the importance of comprehensive diagnostic evaluation in complex pediatric cardiac cases.
- Contributes to the limited literature on common arterial trunk and atrioventricular septal defect associations.
