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