Key result
Open-heart surgery successfully treated a 10-year-old female with a large right atrial aneurysm and secundum atrial septal defect, resulting in complete symptom resolution at 1-year follow-up.
Why the study?
Right atrial aneurysms are rare and can cause arrhythmias, heart failure, rupture, or thromboembolic events if untreated.

Large right atrial aneurysms can be safely and effectively managed with surgical resection using cardiopulmonary bypass, with initial peripheral cannulation recommended to decompress the heart and prevent rupture during sternotomy.
BACKGROUND: Right atrial aneurysms are rare. If left untreated, they can result in arrhythmias, heart failure, catastrophic rupture, and thromboembolic phenomena. CASE PRESENTATION: We present the case of a 10-year-old African female who presented with heart failure. The patient underwent successful open-heart surgery to close the atrial septal defect, resect the right atrial aneurysm, and directly close it. Initial peripheral cannulation was performed to decompress the heart, allowing for a safe sternotomy before transitioning to aorto-bicaval cannulation. CONCLUSION: Surgery remains the best option for managing this condition.

Ariaka et al. (2025) conducted a case report in Right atrial aneurysm and secundum atrial septal defect (n=1). Open-heart surgery (ASD closure and RAA resection) was evaluated on Symptom resolution and surgical success. Open-heart surgery successfully treated a 10-year-old female with a large right atrial aneurysm and secundum atrial septal defect, resulting in complete symptom resolution at 1-year follow-up.
