The aorta is made up of different sections, and the ascending aorta is the section that extends from the heart to the arch of the aorta. The upper limit of standard reference range of the ascending aorta may be up to 4.3cm among large, elderly individuals.[5]. Aneurysmal dilatation is considered when the ascending aortic diameter reaches or exceeds 1.5 times the expected normal diameter (equal to or greater than 5 cm). International guidelines use uncorrected aortic diameter to estimate the risks of aortic dissection, rupture, or death among patients with TAAA. An important issue (the aortic size paradox) is addressed in this article, which has a significant bearing on surgical intervention for ascending aneurysms. Bookshelf Distributions of aortic size at both the sinuses of Valsalva and the ascending aorta, measured leading edge-to-leading edge, are shown for men and women, with separate distributions presented for rowers and runners.
