Early Structural Valve Deterioration of the Mitroflow Aortic Bioprosthesis [PDF]

Circulation, 2014
There has been a trend toward more frequent use of bioprosthetic valves, especially in the young generations, over the last decade.1,2 According to the Society of Thoracic Surgeons database, use of bioprosthetic valve increased from 44% in 1996 to 78% in 2006 in North America.1 Freedom from warfarin use and restrictions on diet and activities make ...

Structural Deterioration Localisation Using Enhanced Autoregressive Time-Series Analysis [PDF]

, 2020
Irrespective to how well structures were built, they all deteriorate. Herein, deterioration is defined as a slow and continuous reduction of structural performance, which if prolonged can lead to damage. Deterioration occurs due to different factors such

Bioprosthetic Valve Deterioration

JACC: Basic to Translational Science, 2023
Summary: Histologic evaluations revealed excessive accumulations of macrophages and absence of fibroblastic interstitial cells in explanted bioprosthetic valves. Comprehensive gene and protein expression analysis and histology unveiled an accumulation of

Is cell regeneration and infiltration a double edged sword for porcine aortic valve deterioration? A large cohort of histopathological analysis

BMC Cardiovascular Disorders, 2022
Background and objective Bioprostheses are the most common prostheses used for valve replacement in the Western medicine. The major flaw of bioprostheses is the occurrence of structural valve deterioration (SVD).

Considerations When Evaluating Structural Valve Deterioration

Journal of the American College of Cardiology, 2018
Rodriguez-Gabella et al. [(1)][1] have recently published outcomes of 672 patients who underwent aortic valve replacement focusing on structural valve deterioration (SVD). The authors warned about the difficulty of comparing studies due to the different definitions of SVD.

Early Structural Deterioration of a Sutureless Bioprosthetic Aortic Valve

Cardiology Research, 2020
Sutureless bioprosthetic valves such as the Sorin Perceval S valve (SPV) have been used in patients with aortic stenosis that require surgical aortic valve replacement (SAVR). These prostheses have been marketed on the basis of their rapid implantation techniques with avoidance of sutures and reduced aortic cross-clamp times.
