A 72-year-old male patient presented with a complaint of pain in both legs during short walks of less than 50 meters. Physical examination showed weak arterial pulses in both lower extremities. Electrocardiographic and telecardiographic evaluations were normal. A previous abdominal ultrasonography examination performed for abdominal pain showed an abdominal aortic aneurysm. Coronary angiography findings were normal; however, peripheral angiography showed an abdominal aortic aneurysm and extensive critical bilateral peripheral artery disease. Transthoracic echocardiography disclosed an aneurysmal structure neighboring the right atrium. Transesophageal echocardiography demonstrated a 30x18-mm chamber suggestive of a right atrial appendage aneurysm. Cardiac magnetic resonance imaging confirmed the presence of the right atrial appendage aneurysm, 25x15 mm in size, over the tricuspid valve. The neck of the aneurysm was 11 mm. The patient underwent surgery which included grafting of the a...

Aneyrysm of left Atrial appendage (LAAA) is a rare cardiac anomaly. It was first identified in 1960. 1 As severe complications like thromboembolic events, rhythm disorders and CCF surgical management is recommended. The authors presented a 24 years old boy who was hospitalized with a LAAA. It was detected incidentally by CT Scan of the chest. The patient underwent operation with removal of aneurysm under cardiopulmonary bypass. Case Presentation Masum Billah of 21 years boy was attended in outpatient department with non specific presentation. A Thoracic Xray was done and suspected as a case of posterior mediastinal mass. A contrast CT scan was done and diagnosed as a case of giant LAAA (90 mm × 75 mm). For Cardiac evaluation Echocardiography was done and revealed large 90 mm x 70 mm LAAA enlarged compressing the left ventricle. The other findings of Echocardiography was within normal limit. Doing all necessary investigations the patient was scheduled to undergo surgery on 04/10/2020.
