6.1.3.2. BAV Aortopathy Interventions: Replacement of the
Aorta in Patients With BAV
COR LOE
Recommendations
1 B-NR 1. In patients with a BAV and a diameter of the aortic root,
ascending aorta, or both of ≥5.5 cm, surgery to replace the
aortic root, ascending aorta, or both is recommended.
2a B-NR 2. In patients with a BAV and a cross-sectional aortic root or
ascending aortic area (cm
2
) to height (m) ratio of ≥10 cm
2
/m,
surgery to replace the aortic root, ascending aorta, or both
is reasonable, when performed by experienced surgeons in a
Multidisciplinary Aortic Team.
2a B-NR 3. In patients with a BAV, a diameter of the aortic root or
ascending aorta of 5.0 cm to 5.4 cm, and an additional risk
factor for aortic dissection (Table 14), surgery to replace
the aortic root, ascending aorta, or both is reasonable, when
performed by experienced surgeons in a Multidisciplinary
Aortic Team.
2a B-NR 4. In patients with a BAV who are undergoing surgical aortic
valve repair or replacement, and who have a diameter of
the aortic root or ascending aorta of ≥4.5 cm, concomitant
replacement of the aortic root, ascending aorta, or both is
reasonable, when performed by experienced surgeons in a
Multidisciplinary Aortic Team.
2b B-NR 5. In patients with a BAV, a diameter of the aortic root or
ascending aorta of 5.0 cm to 5.4 cm, no other risk factors for
AoD (Table 14), and at low surgical risk, surgery to replace the
aortic root, ascending aorta, or both may be reasonable, when
performed by experienced surgeons in a Multidisciplinary
Aortic Team.
