Abstract An 89-year-old female patient presented to our cardiology outpatient clinic complaining of shortness of breath and back pain. Chest X-ray demonstrated a widened mediastinum. Transthoracic echocardiography showed an ascending aortic aneurysm and the modified apical 5-chamber view showed that left atrium was compressed between the ascending and descending aortas. Color Doppler turbulence was also seen in the compressed area. A contrast-enhanced chest computed tomography scan in axial and coronal planes showed that left atrium and pulmonary veins were compressed by ascending and descending aortic aneurysms. Herein, we illustrated this rare condition diagnosed by transthoracic echocardiography in combination with computed tomography.
