Standardized Definition of Structural Valve Degeneration for Surgical and Transcatheter Bioprosthetic Aortic Valves [PDF]

Circulation, 2018
Bioprostheses are prone to structural valve degeneration, resulting in limited long-term durability. A significant challenge when comparing the durability of different types of bioprostheses is the lack of a standardized terminology for the definition of a degenerated valve.

Early Structural Valve Degeneration of Trifecta Bioprosthesis [PDF]

Annals of Thoracic Surgery, 2020
BACKGROUND Structural valve deterioration (SVD) is a major flaw of bioprostheses. We recently observed an apparent increase in the SVD rate among those received the Trifecta bioprosthesis.

Structural valve degeneration in the transcatheter mitral valve implantation era

Journal of Cardiac Surgery, 2021
Structural valve degeneration of biological valves continues to be a persistent problem and has assumed greater importance with the advent of transcatheter valve implantation techniques.

Clinical and Experimental Studies of Structural Valve Degeneration of Bovine Jugular Vein Valves: Mitigation with Polyoxazoline Modification. [PDF]

Pediatr Cardiol
Bovine jugular vein (BJV) valves are widely used in congenital heart surgery but are limited in durability due to structural valve degeneration (SVD). Here, we examine mechanisms of BJV prosthesis failure and test BJV modification with poly-2-methyl-2 ...

Rates and Predictors of Structural Valve Degeneration and Failure of Trifecta Bioprosthetic Valve Over a 5-year Follow-up Period: A Single-center Experience. [PDF]

J Cardiovasc Echogr
Introduction: The Trifecta bioprosthetic valve has been commonly used for surgical aortic valve replacement (SAVR). Multiple studies have been done to define the rate of structural valve degeneration (SVD) and failure (SVF), but the outcomes are still ...

Modern understanding of mechanisms of bioprosthetic valve structural degeneration: a literature review [PDF]

Российский кардиологический журнал, 2018
Bioprosthetic valves are often used to replace diseased heart valves. They differ from mechanical valves by optimal hemodynamic parameters and low thrombogenicity.

Low Incidence of Structural Valve Degeneration With the Trifecta Aortic Valve Bioprosthesis. [PDF]

, 2021
Objectives: An ideal bioprosthetic heart valve would have excellent haemodynamic performance and a low rate of Structural Valve Degeneration (SVD).

Untreatable Severe Structural Degeneration of a Transcatheter Aortic Heart Valve

JACC: Case Reports, 2020
We describe a patient who presented with heart failure 7 years post-transcatheter aortic valve implantation (TAVI) as a result of severe structural valve degeneration.

Lipoprotein(a) and long-term structural valve degeneration of aortic bioprostheses.

European Heart Journal - Cardiovascular Imaging
AIMS Structural valve degeneration (SVD) is the leading cause of late bioprosthetic valve failure. Lipoprotein(a) [Lp(a)] contributes to native aortic valve calcification, but its role in SVD is unclear.
