A 32-year-old man with a quadricuspid aortic valve. The standardization principles of conservative aortic valve surgery by Lansac et al. were applied, addressing the three elements that support aortic valve physiology: cusps, root diameters (aortic annular base and sinotubular junction), and root dynamics. The annulus dilation was corrected by applying an expansible aortic ring in a subvalvular position. The authors remodeled the aortic root, reducing the sinotubular junction diameter and respecting the root dynamics with the Yacoub technique, and successfully performed the bicuspidization and re-suspension of the leaflets.

Care fo conduction system on annular ring sutures due to quadricuspid aortic valve which might have  another abnormal anatomic change.
Bicuspidication
 Pros: easy
 Cons: aortic valve stenosis in future
