■ Figure 13-17 Transesophageal echo image of the descending thoracic aorta demonstrating a dissection flap (arrow), which creates a true lumen (TL)w
and false lumen (FL) in the short axis (left) and long axis (right). (Echo courtesy of University of Washington Medical Center, Seattle, Washington.)

■ Figure 13-18 Left: A normal left atrial appendage (LAA) is a pouch-like structure arising from the left atrium. This LAA does not contain
thrombus. Mitral stenosis and atrial fibrillation are risk factors for thrombus formation in the LAA. Right: Large thrombus (*) within the LAA.
This patient had atrial fibrillation. (Echo courtesy of University of Washington Medical Center, Seattle, Washington.)

■ Figure 13-19 Left: Transesophageal echo image demonstrating normal aortic valve leaflets (arrow) in diastole. Right: Thickened aortic valve
leaflets with masses attached, all consistent with infectious endocarditis. (Echo courtesy of University of Washington Medical Center, Seattle,
