Conclusion: Aortic root dimensions are affected by age and gender. After BSA correction, females show larger aortic root dimensions than males, and aortic root diameters increase with age.

Patient age can be a critical factor in evaluating the need for aortic root surgery. Dr. Castro states, “The younger you are, definitely the more likely it is that these aneurysms, they don’t get smaller. They get larger with time. If you were 75 years old, it might be something that you could live with to get you to 90.

Formulas: < 20 yrs old : SOVd = 1.02 + 0.98 x BSA 20-39 yrs old : SOVd = 0.97 + 1.12 x BSA > 40 yrs old : SOVd = 1.92 + 0.74 x BSA

Normalized diameters for the dynamic aortic root vary among the age groups. There are apparent relationships between the dynamic diameters and age, body surface area, weight, and height of the patient. The shape of the aortic root is consistent, though its diameter can vary considerably.

Aortic size varies between individuals and is influenced by age, gender, body size and blood pressure. There are numerous studies aimed at defining normative aortic root measurements, but the vast majority of these are in older adults, or limited by a small sample size.
