Transesophageal echocardiography in the diagnosis of acute aortic syndrome

In recent years, technological advances in echocardiography have led to improvements in the diagnosis of acute aortic disease. With transesophageal echocardiography (TEE) and, particularly, bi- and multiplane probes, the physiopathologic understanding of these diseases has widened. Thus, new entities such as penetrating ulcer and intramural hematoma have been described and differentiated from classical aortic dissection.
