None:
A unicuspid aortic valve morphology is a relatively rare variant and may require surgical correction early in life for regurgitation. In the majority of cases, a patch is required for repair, which degenerates and thus limits the durability of valve repair. The bicuspidization of a unicuspid aortic valve without the use of patch material is possible in cases with a symmetric cusp nadir. Unicuspid aortic valves are often accompanied by root enlargement and require root stabilization. Whenever possible, we repair these valves without the use of patch material and with annular stabilization by using a suture annuloplasty.
