Formulae to calculate the predicted effective aortic diameter as a function of subjects age

Aortic level	Formulae	R2
Aortic root	EAD=0.0045 (age)3-0.1647 (age)2+2.5385 (age) + 10.09	0.9443
Ascending aorta	EAD=0.0035 (age)3-0.1278 (age)2+2.0796 (age) + 8.25	0.937
Arch of aorta	EAD=0.0021 (age)3-0.0831 (age)2+1.5785 (age) + 7.579	0.903
Proximal descending Aorta	EAD=0.0024 (age)3-0.0796 (age)2+1.2802 (age) + 6.064	0.9122
Aorta at diaphragmatic hiatus	EAD=0.0023 (age)3-0.0743 (age)2+1.2337 (age) + 5.71	0.9195
