Repair of a unicuspid aortic valve with root stabilization.

Area of Science:

• Cardiovascular Surgery
• Congenital Heart Disease
• Cardiac Valve Repair

Background:

• Unicuspid aortic valve (UAV) is a rare congenital anomaly often requiring early surgical intervention for regurgitation.
• Traditional UAV repair frequently uses patch material, which can degenerate, limiting long-term durability.
• UAVs are commonly associated with aortic root enlargement, necessitating concurrent root stabilization.

Purpose of the Study:

• To evaluate the feasibility and efficacy of bicuspidizing unicuspid aortic valves without patch material.
• To assess the use of suture annuloplasty for aortic root and annular stabilization in UAV repair.
• To improve the durability of aortic valve repair in patients with unicuspid morphology.

Main Methods:

• Surgical bicuspidization of UAVs in cases with symmetric cusp nadir.
• Repair performed without the use of prosthetic patch materials.
• Annular stabilization achieved through suture annuloplasty to address root enlargement.

Main Results:

• Successful bicuspidization of unicuspid aortic valves was achieved in select cases.
• The technique avoided patch material, potentially enhancing long-term valve function.
• Suture annuloplasty effectively stabilized the aortic root and annulus during repair.

Conclusions:

• Patch-free bicuspidization of unicuspid aortic valves is a viable surgical option.
• Suture annuloplasty provides effective stabilization for the aortic root and annulus.
• This approach offers a promising strategy for durable UAV repair, avoiding material degeneration.
