Giant left atrial appendage aneurysm: a case report

A 21-year-old male was referred to the cardiology clinic at Queen Alia Heart Institute for further evaluation upon finding a trial fibrillation and abnormal chest X-ray and on a routine pre-recruitment medical check-up. Trans-thoracic echocardiography suggested the diagnosis of left a trial appendage aneurysm versus pericardial cyst. Transesophageal echocardiography and subsequent cardiac catheterization confirmed the presence of a giant left a trial appendage aneurysm. He underwent uneventful surgical excision. Cardiac rhythm reverted spontaneously to sinus rhythm that was maintained twelve months later
