2d parasternal long axis

Focused view of aortic root and ascending aorta. A protruding atheroma of posterior sino-tubular junction can be seen in systole (white arrow). The atheroma does not cause flow disturbances (color aliasing) near the posterior aortic wall. Detection of the atheroma must rely on focused imaging of the aortic walls and close inspection of the 2D image


Aortic Arch: Mobile Atheromas

2d, jugular view, long axis of aortic arch
2d, jugular view, short axis of aortic arch
color Doppler, jugular view, long axis of aortic arch
Ath: atheroma; SAB: supra-aortic branches
PA: pulmonary artery

(tt3430) M, 70 y.
Severe mobile atheromas of the aortic arch with thrombi. Pre-operative examination for aneurysm of abdominal aorta.


Aortic Arch Atheroma & Calcification

2D Jugular long axis of aortic arch.
Examination for severe AR.
Calcific plaque and atheroma (not mobile) on inner (inferior) wall of the aortic arch.
AO: aortic arch; BCT: brachio cephalic trunk; LCA: left carotid artery.

(tt2732) F, 68 y. Sonos 2000. Chest pain and LBBB. Aortic dissection type A, anterior wall of ascending aorta (see intimal mobile flap in 2D parasternal and jugular views, and M-mode) between sino-tubular junction and brachiocephalic branch. Note color Doppler flow in aortic true lumen distal to flap in arch. Associated moderate AR. See also intra-operative TE exam (te0373)
