A rare giant right atrial aneurysm was found in a 2-year-old boy. Surgical repair successfully reduced the atrium and closed a heart defect, preventing future complications.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Massive cardiomegaly in a pediatric patient can indicate rare cardiac anomalies.
- Right atrial aneurysms are uncommon congenital heart malformations.
Observation:
- A 2-year-old boy presented with incidental massive cardiomegaly on chest X-ray.
- Echocardiography revealed a giant right atrial aneurysm.
Findings:
- The resected atrial tissue showed paper-thin walls with interstitial fibrosis and endocardial thickening.
- Successful surgical reduction of the right atrium and patent foramen ovale closure were performed.
Implications:
- Surgical intervention can effectively manage giant right atrial aneurysms in children.
- Closure of patent foramen ovale prevents thromboembolic events and reduces arrhythmia risk.
