Case in brief
An adolescent with a unicuspid aortic valve exhibiting stenosis and regurgitation underwent a novel tricuspidization procedure. This involved selectively replacing a dysplastic cusp with autologous pericardium and creating two neocommissures, effectively converting the valve to a tricuspid configuration while preserving native tissue. Postoperative follow-up showed competent valve function and a low transvalvular gradient.
Diagnostic / clinical pearl
The tricuspidization technique allows for effective repair of unicuspid aortic valves in adolescents, preserving native tissue and potentially delaying the need for definitive valve replacement.
Why it matters
This approach may provide a growth-preserving option for pediatric patients with unicuspid aortic valves, addressing both stenosis and regurgitation while maintaining valve function.
