Identification of the Aortic Arch Branches Using Transesophageal Echocardiography.

In this report we describe the technique used for identification of the individual aortic arch vessels using transesophageal echocardiography.

Transesophageal Echocardiographic Imaging of the Left Atrium Behind the Ascending Aorta Mimicking Aortic Dissection Validation by Contrast Echocardiography.

We describe the presence of a localized echo-free space behind the ascending aorta, which could mimic an aortic dissection. This space was confirmed to be the left atrium by intraoperative contrast echocardiography.
