Imaging findings
The imaging demonstrates both atrial appendages (left and right) are located on the same side of the great arteries, specifically on the left. The patient also has complex congenital heart disease, including a D-transposition of the great arteries and a baffle procedure within the atria, along with a tricuspid valve anomaly.
Key takeaways
Juxtaposed atrial appendages occur when both atrial appendages are situated on the same side of the great vessels, most commonly on the left. This rare anatomical variant is almost invariably associated with complex cyanotic congenital heart disease. Understanding this anomaly is crucial for surgical planning and the management of associated cardiac defects.
