In bicuspid aortic valve-associated aortopathy, the maximum aortic diameter is the central parameter driving clinical decision-making. Once that diameter reaches 55 mm or more at any level, a specific management threshold is crossed.
This protocol is for patients with bicuspid aortic valve-associated aortopathy whose maximum aortic diameter has reached ≥55 mm at any aortic level.
A maximum diameter of ≥55 mm at any level is the defining threshold — it mandates a specific intervention regardless of where along the aorta the measurement is taken.
Once this aortic diameter threshold is met, the recommended approach involves surgical management of the aortopathy. The complete structured regimen — including operative criteria, procedural details, and decision algorithm — is available in the full protocol.
