Evidences of abdominal aorta stenosis in case 1. (A) Two-dimensional and color Doppler echocardiographic image revealed the stenosis of the descending abdominal aorta (left) and turbulent flow through narrowed segment on color Doppler (right). (B) Peak velocity and peak pressure gradient were 5.1 m/s and 105 mmHg, respectively, on continuous wave Doppler echocardiographic image. (C) Angiography and (D) three-dimensional reconstructed image of computed tomography angiogram revealed a significant stenosis of the suprarenal abdominal aorta (black and white arrows).

The results of the subcostal four-chamber view imaging of the abdominal aorta revealed small-caliber abdominal aorta (Figure 1A) with marked flow acceleration (peak velocity =5.1 m/s) (Figure 1B). Subsequent aortic angiogram (Figure 1C) with aortic pressure measurement showed 88 mmHg systolic pressure gradient at the mid thoracic aorta.

Echocardiographic and angiographic findings of case 2. Parasternal long axis view of a two-dimensional echocardiographic image showing (A) left ventricular hypertrophy and (B) aortic regurgitant jet. Angiography revealed (C) total occlusion of the left common carotid artery and (D) diffuse narrowing of the thoracoabdominal aorta with a 8.2-mm minimal lumen diameter.

Following echocardiography showed marked LVH and moderate to severe aortic regurgitation (Figure 2A,B).
