[Dimensions of the aortic ring. Anatomic and surgical study of 2 series of patients]

Both surgical (236 aortic valve replacements) and anatomical (62 dissections) studies have defined the aortic annulus diameter. Measurements (23.5 mm for women; 26 mm for men) are more considerable than established values. Furthermore, surgical study allows the authors to compare these results to several variables, more especially corporeal surface and stature: the height's increase perhaps explains the large sizes discovered.
