The range of mean ascending aortic diameters (including gated and nongated examinations) in the literature by computed tomography (CT) ranges from 29.0 to 37.2 mm for females, and 30.8 to 39.1 mm for males. An ascending aortic diameter greater than 4 cm is considered to indicate dilatation. 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). Surgery on an ascending aortic aneurysm of degenerative etiology is usually suggested when the aneurysm reaches 5.0 to 5.5 cm or a documented growth rate greater than 0.5 cm/year. Surgery is recommended for symptoms attributable to the aneurysm, diameter ≥5.5 cm, or rapid growth; and reasonable at the time of tricuspid aortic valve replacement with an aortic diameter ≥5.0 cm.
