Degenerative processes in bioprosthetic mitral valves in juvenile pigs [PDF]
Journal of Cardiothoracic Surgery, 2011 Background Glutaraldehyde-treated bioprosthetic heart valves are commonly used for replacement of diseased heart valves. However, calcification and wear limit their durability, and the development of new and improved bioprosthetic valve designs is needed

Bioprosthetic Aortic Valve Fracture During Valve-in-valve Transcatheter Aortic Valve Implantation [PDF]
Interventional Cardiology: Reviews, Research, Resources, 2019 The limited durability of surgical bioprostheses, combined with an ageing population, has led to an increasing demand for replacing degenerated bioprosthetic surgical heart valves, which is projected to increase. Valve-in-valve transcatheter aortic valve

Development of methods for the tissue engineering of cardiac valves using mesenchymal stem cells [PDF]
, 2004 Cardiac valve replacement is the second most common heart operation in the Western World. Valve replacements currently available are poorly adapted for use in young patients who typically require multiple re-operations as they grow, resulting in ...

Multiscale Multimodal Characterization and Simulation of Structural Alterations in Failed Bioprosthetic Heart Valves. [PDF]
, 2023 Calcific degeneration is the most frequent type of heart valve failure, with rising incidence due to the ageing population. The gold standard treatment to date is valve replacement.

Early calcific degeneration of the St. Jude Medical Epic aortic bioprosthesis
Clinical Case Reports, 2020 This report highlights the need for close surveillance of bioprosthetic valves. Unaccountable degeneration of bioprosthetic valves can develop early after implantation and usually requires replacing the failed valve with a mechanical prosthesis.
