In patients with aortic dilatation, the aortic wall can be weakened by cystic media degeneration.Transthoracic echocardiography is a basic modality to assess patients with coronary artery disease and can be used for the screening of aortic aneurysm. It is known that dilatation of the aorta is a precursor for life threatening aortic aneurysm leading to rupture or dissection (1,2,3). Top bar graph shows the flow velocity ratio of the right carotid artery (RC) vs the left carotid artery (LC) 1 week after TAC.
