Bicuspid Aortic Valve Disease and Ascending Aortic Aneurysms: Gaps in Knowledge
Table 3
Criteria for elective replacement of the ascending aorta in patients with BAV.
| AHA/ACC guidelines | | Class I | | (1) Aortic diameter >5.0 cm | | (Level of evidence: B) | | (2) Aneurysm growth rate >0.5 cm/year | | (Level of evidence: B) | | (3) Aortic diameter >4.5 cm with concomitant indication for elective aortic valve repair/replacement | | (Level of evidence: B) | |
| Aortic size ratios and indexes | | Aortic diameters >4.5 cm and either of the following: | | (1) Ratio of aortic area to body height >10 cm2/m in asymptomatic patients with well-functioning BAV, or 8-9 cm2/m in symptomatic patients [91] | | (2) Ratio of aortic diameter to body surface area >4.5 cm/m2 [92] | |
| Other criteria (unvalidated) | | Aortic diameters >4.5 cm and any of the following: | | (1) Aortic coarctation, corrected or uncorrected [93] | | (2) First-degree relative with ascending aortic dissection or rupture | | (3) Long smoking history, especially with COPD [94, 95] | |
