Etymology: Gk, thorax, chest, aerein, to raise
the large upper part of the ascending arch and descending aorta, supplying many parts of the body, such as the heart, ribs, chest muscles, and stomach. Its branches include the coronary brachiocephalic, left common carotid artery, left subclavian, pericardial, bronchial, esophageal, mediastinal, posterior intercostal, subcostal, and superior phrenic. See also descending aorta. Compare abdominal aorta.

Furthermore, anatomical grouping of more levels was operated for compartmental comparison of the median of quantitative parameters, as follow: a) thoracic aorta, including from aortic valve to descending aorta (levels 1, 2, and 3 of quantitative analysis); b) abdominal aorta, including diaphragmatic aorta and aorta at the level of renal arteries origin (levels 4 and 5 of quantitative analysis).

This was followed by noninvasive imaging with CT or MR angiography for ascending aorta, arch vessels, descending thoracic aorta and abdominal aorta with its branches.
We believe that transesophageal echocardiography is an extremely useful tool, and it is now used widely for the detection of aortic diseases (5) because the entire thoracic aorta and left main coronary ostium can be viewed, and any aortic regurgitation can be easily seen.
