Echocardiography of the Aortic Root
Following the first description of the aortic root echogram by Gramiak and Shah  in 1970, M-mode echocardiography was found useful in detecting dilatation of the ascending aorta [2–6] as an abnormally wide separation between echoes of the anterior and posterior aortic root respectively. Aortic dissection can also be diagnosed by the M-mode technique [7–12] but one should be wary of false-positives and the diagnosis should be seriously considered only if several criteria are present [13–16].
