Table 2.

Aortic measurements shown as mean, (standard deviation), and [95% confidence interval] were compared between AA and C patients with BAV by multivariate linear regression analysis as unadjusted measurements or *adjusted for age, gender, hypertension, moderate-severe aortic stenosis/insufficiency, and use of beta blocker or ACE-inhibitors or ARB's and show significant smaller aortic dimension in AA patients with BAV.
