Key result
Patchless bicuspidization with suture annuloplasty proves feasible for unicuspid aortic valves with symmetric cusp nadirs.
Why the study?
Unicuspid aortic valve repair typically requires a patch that degenerates and limits durability, and these valves often feature root enlargement requiring stabilization.
Bicuspidization of a unicuspid aortic valve without patch material, combined with suture annuloplasty for root stabilization, is a feasible surgical technique for patients with a symmetric cusp nadir.
May allow patchless bicuspidization in select symmetric unicuspid aortic valves; leaves open durability assessment in prospective cohorts.
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.

Konstantinov et al. (2026) studied Unicuspid aortic valve regurgitation. Bicuspidization without patch material and annular stabilization using suture annuloplasty was evaluated. Bicuspidization of a unicuspid aortic valve without patch material and with annular stabilization using suture annuloplasty is a feasible surgical technique for cases with a symmetric cusp nadir.
