Abstract:
Congenital right atrial aneurysm (RAA) is a rare anomaly that may cause arrhythmias, thromboembolism, or heart failure. We report a prenatally diagnosed RAA with coexisting tricuspid valve (TV) dysplasia. Postnatally, the patient showed progressive atrial enlargement, and TV regurgitation. At 9 months, surgery was performed due to high thromboembolic and arrhythmic risk, including aneurysmal wall resection and TV repair. Postoperative recovery was uneventful. In conclusion, this case underscores the need for comprehensive imaging and individualized management in RAA, especially when coexisting valvular abnormalities are present.
