Bioprosthetic heart valves of the future. [PDF]

open access: yesXenotransplantation, 2014
AbstractGlutaraldehyde‐fixed bioprosthetic heart valves (GBHVs), derived from pigs or cows, undergo structural valve deterioration (SVD) over time, with calcification and eventual failure. It is generally accepted that SVD is due to chemical processes between glutaraldehyde and free calcium ions in the blood.

Dynamic Echocardiographic Imaging of a Valve-in-Valve Mitral Prosthesis

open access: yesCase Reports in Radiology, 2022
Dynamic imaging of heart valves and specifically prosthetic valves is a central benefit of echocardiography. Most bioprosthetic heart valves degenerate over a given time and hence require repeat valve replacement which carries a significant risk of ...

Polyvinyl alcohol improves resistance of epoxy-treated bovine pericardium to calcification in vitro

open access: yesТрансплантология (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.

Characterization of immunogenic Neu5Gc in bioprosthetic heart valves. [PDF]

open access: yesXenotransplantation, 2016
AbstractBackgroundThe two common sialic acids (Sias) in mammals are N‐acetylneuraminic acid (Neu5Ac) and its hydroxylated form N‐glycolylneuraminic acid (Neu5Gc). Unlike most mammals, humans cannot synthesize Neu5Gc that is considered foreign and recognized by circulating antibodies.

Midterm outcomes of mechanical versus bioprosthetic valve replacement in middle-aged patients: An Indian scenario

open access: yesHeart India, 2017
Objective: The goal of this study is to evaluate and compare the midterm outcomes of bioprosthetic heart valve replacement in terms of survival, valve-related events, quality of life, and economic aspects of treatment in population age 45 years and above

Recurrent infective endocarditis causing heart valve failure: A case report

open access: yesHuman 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 ...

Sevelamer Attenuates Bioprosthetic Heart Valve Calcification [PDF]

open access: yesFrontiers in Cardiovascular Medicine, 2021
Objective: Sevelamer hydrochloride is a phosphate binder used to treat hyperphosphatemia in chronic kidney disease (CKD) patients that can reduce valvular and vascular calcification. The aim of this study was to examine the effects of sevelamer treatment on calcification in bioprosthetic heart valves (BHVs).Methods: Wister rats were randomly divided ...

Retrospective Observational Analysis of Outcomes After Surgical Valve Replacement: A 15 Years' Experience in a Tertiary Care Hospital

open access: yesJournal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2023
Background: None of the currently available prosthetic valves are comparable to native valves in hemodynamic functions. One has to choose between durability, thrombogenicity, or risk of major bleeds.
