However, after adjustment on aortic diameter and age, only the sinus of Valsalva remained stiffer (p&lt;0.001), whereas the tubular aorta no longer differed (p=0.610). In patients with BAV, aortic diameters were not influenced by the valve morphotype, except for the arch, which was more dilated in the case of 1- Non coronary sinus-Right subtype of BAV : 36.1 vs 27.6\u2009mm, p&lt;0.001. Aortic regurgitation was associated with an increase in aortic diameters at the sinus of Valsalva (p&lt;0.001) and the tubular aortic levels (p=0.04).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Stiffness increase at the sinus of Valsalva level is independent of aortic dilatation in patients with BAV, contrary to the classic relationship between stiffness and dilatation found on the other segments.
