*Indicates significant differences between BAV and DA.
†Indicates significant differences between BAV and MFS.
‡Indicates significant differences between MFS and DA.
§Indicates significant differences between baseline and follow-up diameters.
Larger baseline aortic diameters in DA patients reflect the inclusion criteria of 40 mm for these patients versus 37 mm for BAV and MFS.
AR, aortic regurgitation; BAV, bicuspid aortic valve; BP, blood pressure; DA, degenerative aortopathy; MFS, Marfan syndrome.
