aortic arch n. 1  The curved portion between the ascending and descending portions of the aorta, lying behind the manubrium and giving rise to the brachiocephalic trunk, the left common carotid, and the left subclavian arteries. Also called arch of aorta.

When the analysis was stratified by age, we found that aortic arch calcification is more strongly related to CHD among men aged 65 years and older (relative risk, 1.48; 95% CI, 1.20-1.83) than among men aged 30 to 64 years and older (relative risk, 1.09; 95% CI, 0.92-1.29).

The aortic arch loops over the left pulmonary artery and the bifurcation of the pulmonary trunk, to which it remains connected by the ligamentum arteriosum, a remnant of the fetal circulation that is obliterated a few days after birth. In addition to these blood vessels, the aortic arch crosses the left main bronchus.

The aorta is divided into four sections: • The ascending aorta rises up from the heart and is about 2 inches long. The coronary arteries branch off the ascending aorta to supply the heart with blood. • The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms.

The aorta (/eɪˈɔːrtə/) is the main artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.

The only significant age by aortic arch calcification status interaction was in the model of CHD among men. Given the high level of statistical significance (P<.001), this interaction is not likely due to multiple testing.

The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle, the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve.

However, the incremental predictive value of vascular calcification, beyond traditional coronary risk factors, is not clearly established. Objective To evaluate risk factors for aortic arch calcification and its long-term association with cardiovascular diseases in a population-based sample.
