Aortic root size calculator

Use our aortic root size calculator to calculate accurate size and measurement values instantly.

Calculator

Calculate Body Surface Area and estimated maximum Sinus of Valsalva (SOV) diameter from height, weight, and age, with optional adult vessel percentile estimates.

Units

Formula: Bernoulli Equation (reference formulas): <20 yrs SOVd = 1.02 + 0.98 x BSA; 20-39 yrs SOVd = 0.97 + 1.12 x BSA; >40 yrs SOVd = 1.92 + 0.74 x BSA
