Imaging of Bioprosthetic Valve Dysfunction after Transcatheter Aortic Valve Implantation
Diagnostics, 2023 Transcatheter aortic valve implantation (TAVI) has become the standard of care in elderly high-risk patients with symptomatic severe aortic stenosis. Recently, TAVI has been increasingly performed in younger-, intermediate- and lower-risk populations ...

Вестник трансплантологии и искусственных органов, 2022 Current research shows that some of the pathogenetic processes behind structural destruction of bioprosthetic valves are largely similar to those involved in the development of atherosclerotic vascular lesions and native valve calcification.

Porcine or Bovine Tissue Valves: Which are Better for Surgical Aortic Valve Replacement? [PDF]
Journal of Biomedical & Clinical Research, 2023 The choice between mechanical and bioprosthetic aortic valve implants is affected by relatively clear criteria. However, the choice between porcine or pericardial valve is more complex regarding bioprosthetic devices.

Non-linear finite element analyses of the aortic heart valve [PDF]
, 2004 Includes bibliographical references.Finite element models of the aortic heart valve have been successfully used in the past to gain insight into the mechanics of the valve and to aid in understanding of valve failure.

Polyvinyl alcohol improves resistance of epoxy-treated bovine pericardium to calcification in vitro
Трансплантология (Москва), 2023 Background. Around half of bioprosthetic heart valves become dysfunctional 15 years postimplantation because of structural valve deterioration notable for the degradation and calcification of the prosthetic tissue.

Recurrent infective endocarditis causing heart valve failure: A case report
Human Pathology: Case Reports, 2017 Infective endocarditis (IE) is an infection that does not usually respond rapidly to treatment, often because its early symptoms are non-specific. The diseased valves (native or bioprosthetic) may be calcified and the thrombotic vegetations on them ...

Transcatheter aortic valve implantation in failed bioprosthetic surgical valves. [PDF]
, 2014 IMPORTANCE Owing to a considerable shift toward bioprosthesis implantation rather than mechanical valves, it is expected that patients will increasingly present with degenerated bioprostheses in the next few years.

Transcatheter heart valve in valve implantation with Edwards SAPIEN bioprosthetic valve for different degenerated bioprosthetic valve positions (First Iranian ViV report with mid-term follow up) [PDF]
Journal of Cardiovascular and Thoracic Research, 2017 Introduction: After early successful experience with transcatheter aortic valve replacement (TAVR), concept of transcatheter implantation of a new valve within a failing bioprosthetic valve emerged. Valve-in-valve (ViV) implantation seems to be a simpler
