Abstract: Background: The left atrial appendage aneurysm (LAAA) is extremely rare. It can be caused by congenital dysplasia of the atrial muscles or secondary to mitral valve disease. Most patients are asymptomatic, while palpitations, dyspnea, or chest pain can be found to be main symptoms. Case: we describe the case of 18year old male with congenital aneurysm of left atrial appendage. The patient presented with atrial tachyarrhythmia. The diagnosis was made on transthoracic echocardiography, CECT of thorax and confirmed by histopathological examination (HPE) of excised left atrial appendage aneurysm. Conclusion: LAAA is a rare cardiac anomaly. Echocardiography is considered the initial diagnostic tool, and cardiac CT as well as MRI helps to differentiate it from other abnormalities. The associated high risk of life-threatening complications and the relative ease of surgical removal suggest that prompt evaluation should be considered in patients with lesions adjacent to the left heart border.
