(A) TAA subtypes based on localization within the aortic tree. Within the thoracic aorta, three sections can be differentiated: the ascending aorta runs from the aortic valve in the left ventricle to the brachiocephalic trunk; the aortic arch starts at the second sternocostal joint and finishes at the level of the fourth vertebra, containing the head and neck vessels; and the descending thoracic aorta, which goes beyond the ligamentum arteriosum and ends at the level of the diaphragm. (B) TAA classification as syndromic and non‐syndromic. EDS, Ehlers‐Danlos syndrome; LDS, Loeys‐Dietz syndrome; MFS, Marfan syndrome.
