Cellular Composition of Calcified Bioprosthetic Heart Valves

open access: yesAnnals of the Russian academy of medical sciences, 2015
With the aim to assess the mechanisms of the structural dysfunctions associated with xenograft tissue calcification, we investigated the cellular composition of the explanted xenoaortic epoxy-treated bioprosthetic heart valves. In the leaflets, we revealed multiple cells with retained internal structure.

Hemodynamic comparisons of polyurethane trileaflet and bioprosthetic heart valves

open access: yes, 1989
Hemodynamic comparison of two polyurethane prosthetic heart valves with a bioprosthetic valve is presented. The valves were incorporated in a pulse duplicator simulating physiologic pulsatile flow, and comparisons between the valves were made on the ...

Outcomes of aortic valve surgery for rheumatic heart disease in Indigenous Australians: a 27-year longitudinal study

open access: yesThe Cardiothoracic Surgeon
Background In Australia, acute rheumatic fever occurs almost exclusively in young Indigenous peoples, with young- to middle-aged Indigenous people being predominantly affected by rheumatic heart disease. This can result in a need for aortic valve surgery.

The Therapeutic Potential of H2S‐Releasing Platforms in Cardiovascular Applications

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 8, August 2026.
The Therapeutic Potential of H2S‐Releasing Platforms. ABSTRACT Once known as a toxic gas, hydrogen sulfide (H2S) is now making its way into many therapeutic applications. Similar to its other fellow endogenous gasotransmitters, nitric oxide and carbon monoxide, H2S is a small gas with a short half‐life, making it extremely capable of penetrating ...

Atrial High‐Rate Episodes Mirror Atrial Fibrillation in Stroke Prediction: Evidence From an Indian Prospective Cohort

open access: yesJournal of Arrhythmia, Volume 42, Issue 4, August 2026.
This prospective matched cohort study, which generates hypotheses, finds that device‐detected AF lasting under 24 h is linked to a notably increased risk of stroke/TIA and progression to clinical AF among Indian patients. ABSTRACT Aims To assess the risk of stroke/TIA and progression to atrial fibrillation (AF) in Indian patients with device‐detected ...

Cardiac xenotransplantation technology provides materials for improved bioprosthetic heart valves [PDF]

open access: yes, 2011
ObjectivesHuman subjects and Old World primates have high levels of antibody to galactose-α-1,3 galactose β-1,4-N-acetylglucosamine (α-Gal). Commercially available bioprosthetic heart valves of porcine and bovine origin retain the Gal antigen despite ...
