Ten-year follow-up of unreplaced Valsalva sinuses after aortic valve replacement in bicuspid aortic valve disease.

Ascending aorta and Valsalva sinuses seem to have different fates after AVR in BAV disease. When the Valsalva sinuses are not dilated at the initial surgery, the risk of secondary dilatation at 10 years is low. Preservation of the sinuses is therefore justified in patients with BAV with a non-dilated root. In BAV with isolated aortic insufficiency, a more aggressive approach may be justified, especially in young patients.
