Giant Right Atrial Aneurysm in an Infant

Area of Science:

• Cardiology
• Congenital Heart Disease
• Pediatric Surgery

Background:

• Right atrial aneurysm (RAA) is a rare congenital anomaly.
• Clinical presentation of RAA is diverse.
• Antenatal detection of RAA is uncommon.

Observation:

• A case of a giant RAA detected antenatally is presented.
• The infant experienced staring spells, suspected to be thrombo-embolic events from the RAA.
• The right coronary artery was displaced due to RAA invagination.

Findings:

• Successful surgical resection of the giant RAA was performed.
• The right coronary artery was preserved during surgery.
• The anatomical relationship between RAA and the coronary artery was noted.

Implications:

• This case highlights the importance of antenatal diagnosis of RAA.
• Successful surgical management can prevent serious complications like thrombo-embolism.
• Understanding the anatomical variations associated with RAA is crucial for surgical planning.
