aortic valve neocuspidization
Surgical technique creating new aortic valve leaflets using pericardial tissue or synthetic materials.
Full Definition
Aortic valve neocuspidization is an innovative surgical technique that involves creating new aortic valve cusps using autologous pericardium, treated bovine pericardium, or synthetic materials. This approach is primarily used in patients with bicuspid aortic valves or when valve-sparing procedures are not feasible due to leaflet pathology. The technique involves careful measurement and fashioning of new cusps to restore normal valve geometry and function. Neocuspidization may be performed as part of aortic root replacement procedures and offers an alternative to mechanical or bioprosthetic valve replacement, particularly in younger patients seeking to avoid anticoagulation.
