Oct 21, 2016 · In patients with a dilated proximal ascending aorta and trileaflet aortic valve, we aimed to assess (1) factors independently associated with increased long-term mortality and (2) the incremental prognostic utility of indexing aortic root to patient height.

Feb 24, 2022 · Ascending aorta: Upward curve that occurs shortly after the aorta leaves the heart. Aortic arch: Curved segment that gives the aorta its cane-like shape. It bridges the ascending and descending aorta.

Feb 4, 2025 · The aorta can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta and the abdominal aorta. It terminates at the level of L4 by bifurcating into the left and right common iliac arteries.

The aortic root is asymmetric and cannot be properly measured in 1 random cross-section, especially in patients with BAV. However, the clinical guidelines still regard echocardiography in parasternal long-axis view as the optimal method for the measurement of this structure.

Oct 30, 2023 · Most common one, and the one we will use in this article, is the classification of the aorta into three parts; the ascending aorta, aortic arch and the descending aorta. The descending aorta is the longest part, further subdivided into thoracic and abdominal aorta, with the diaphragm being the anatomical division between the two.

Nov 29, 2016 · In patients with dilated aortic root and trileaflet aortic valve, a ratio of aortic root area to height provides independent and improved stratification for prediction of death.

Locate the cross section of the muscular artery, which can be identified by its thick wall and the scalloped luminal surface. The major component of the wall of the artery is spirally arranged smooth muscle (therefore seen here in longitudinal section).

Jul 25, 2023 · The superior aspect of the aortic arch is commonly found in the Plane of Ludwig, a transverse cross-section between the T4 vertebrae and the second sternocostal articulation, commonly demarcated by the sternal angle. The brachiocephalic, left common carotid, and left subclavian arteries all branch off the aortic arch.

Stanford type A aortic dissection is described as the unstable and fatal rupture of aortic wall involving the ascending aorta and arch.

Mar 2, 2025 · This arch-shaped section sits above the heart in the upper chest and forms an important landmark in chest imaging. The arch typically gives rise to three major blood vessels that supply blood to your head, neck, and arms. ... CT angiography (CTA) provides detailed cross-sectional images of the aortic arch and surrounding structures. This ...
