Both surgical and transcatheter aortic and mitral bioprosthetic valves have limited durability and are prone to structural valve deterioration. * Consideration only of valve-related reintervention or death underestimates the incidence of structural BVD. * Definition of structural BVD requires confirmation by imaging of permanent structural changes in the leaflets, struts, or stent and hemodynamic deterioration.



Relevance: The main objective of this expert consensus document is to propose or complement standardized definitions and measurement methods of: nonstructural and structural BVD and BVF following aortic or mitral biological valve replacement. These definitions should support standardized reporting in research and help guide clinical practice.
