Microaxial Flow Pump Support as a Bridge to Transaxillary TAVI‐In‐TAVI in Cardiogenic Shock

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT A 79‐year‐old man presented with cardiogenic shock due to severe degeneration of a prior transcatheter aortic valve. Temporary mechanical circulatory support with a transvalvular microaxial flow pump was initiated, resulting in rapid stabilization.

The Therapeutic Potential of H2S‐Releasing Platforms in Cardiovascular Applications

Journal 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 ...

Early comparison of one-year outcomes after aortic mechanical vs. biological valve replacement in Chinese patients with small aortic annulus

Journal of Cardiothoracic Surgery
Background This study compares short-term clinical and hemodynamic outcomes of AVR using mechanical versus bovine pericardial valves in patients with a small aortic annulus (≤ 21 mm) and evaluates the feasibility and safety of AVR in this population ...

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

Journal 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 ...

Bioprosthetic Heart Valves: Impact of Implantation on Biomaterials [PDF]

, 2018
Prosthetic heart valves are commonly used in the treatment of valvular heart disease. Mechanical valves are more durable than the bioprosthetic valves; however, the need for long-term anticoagulant therapy renders them unsuitable for some patient groups.

Study of the kinetic energy anisotropy over spherical shells downstream of stenotic and bioprosthetic aortic valves

, 2023
Haemodynamic transition-to-turbulence due to aortic stenoses or non-optimal bioprosthetic aortic valves (BioAVs) may contribute to a variety of pathophysiological effects (Stein & Sabbah, 1976).

Bioprosthetic heart valves - Replacing order with chaos: Electron microscopic study

, 1999
Rheumatic heart disease is a significant clinical entity in young children; especially in the developing world. One of the major long-term effects of iii managed rheumatic fever is irreversible damage to the cardiac valve leaflets, primarily on the left ...

Transcatheter Aortic Valve Replacement in Failed Transcatheter Bioprosthetic Valves

, 2022
Transcatheter aortic valve replacement (TAVR) is increasingly being performed in younger and lower surgical risk patients. Given the longer life expectancy of these patients, the bioprosthetic valve will eventually fail, and aortic valve reintervention ...

Balloon dilatation of porcine bioprosthetic valves in the pulmonary position.

, 1987
Balloon dilatation (BD) of bioprosthetic valves was investigated in vivo and in vitro. Four children with stenotic bioprosthetic porcine valves in the pulmonary position underwent BD of the valve 10 to 24 months after its insertion.
