Adolescents with bicuspid aortic valve: Which criteria should we use for aortic dilatation?

Background: Criteria to define aortic dilatation in bicuspid aortic valve (BAV) patients are different for children and adults. The objective of this study was to find the best reference tool to define dilation of the aortic root (AR) and the ascending aorta (AA) in BAV adolescents with an adult body surface area (BSA).

Methods: Patients recruited were ≥10-years-old with a BSA ≥1.
