Acute aortic syndromes (AASs) encompass a diverse range of clinical presentations with a highly variable incidence. In addition to the use of non-echocardiographic imaging modalities (e.g., computed tomography angiography), transesophageal echocardiography (TEE) could play a role in surgical decision making.
Figure
(A) Two-dimensional transesophageal echocardiography performed with an X7 2t Philips ultrasound probe and machine (iE33 model; Philips, Bothell, WA, USA). This upper esophageal, long-axis image depicts an intramural hematoma (IMH) in the distal aortic arch, measuring > 7 mm in thickness. (B) Aortic arch, short-axis view shows a penetrating ulcer overlying the IMH (denoted by an arrow). Colour Doppler imaging shows the absence of a false lumen, differentiating IMH from a more typical aortic dissection. In addition, the aortic thickening has a crescentic shape with mixed echogenicity, both of which are distinctive features of an IMH. 2D = two dimensional; TEE = transesophageal echocardiography
