Transesophageal echocardiography relies on the presence of an undulating intimal flap for
the diagnosis of aortic dissection. Furthermore, to distinguish true dissection from echo
artifacts, the flap has to be identified in more than one view, and it must have a motion
independent of the aortic wall. We describe the transesophageal echocardiography
appearance of a localized aortic dissection with atypical features for an intimal flap.
Awareness of this unusual echocardiographic appearance of an intimal flap will avoid …
