Abstract:
Left atrial appendage aneurysm (LAAA) is a rare congenital cardiac anomaly that is associated with potentially life-threatening complications, including thromboembolism and arrhythmias. We report a 36-year-old male patient with giant LAAA (66 × 46 mm) and chronic atrial fibrillation (CAF) presenting with palpitations. Surgical resection of LAAA and Cox-Maze IV procedure were performed under cardiopulmonary bypass. The patient was discharged in sinus rhythm, remained asymptomatic, and had normal echocardiographic findings at follow-up.
