Aortic dissection without intimal tear: case report and findings on transesophageal echocardiography.

Transesophageal echocardiography (TEE) relies on the presence of an intimal flap for diagnosing aortic dissection; however, a small percentage of cases of dissection can occur without apparent intimal disruption. This case reviews unusual echocardiographic features of aortic dissection and previously undescribed echocardiographic findings in a patient with aortic dissection without intimal flap.
