Transapical transcatheter mitral valve implantation with J-valve in patients with degenerated mitral bioprostheses

open access: yesBMC Cardiovascular Disorders, 2023
Background Due to the widespread application of bioprosthetic valve in the treatment of mitral valve disease in recent years, the incidence of valve failure has increased significantly, which is facing the need of reoperation.

A coupled mitral valve -- left ventricle model with fluid-structure interaction

open access: yes, 2017
Understanding the interaction between the valves and walls of the heart is important in assessing and subsequently treating heart dysfunction. With advancements in cardiac imaging, nonlinear mechanics and computational techniques, it is now possible to ...

Age and gender effects on echocardiographic and histopathological cardiac phenotypes in healthy adult mice

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study investigated the impact of age and sex on cardiac phenotypes in healthy adult C57BL/6J mice using echocardiography and histopathological analyses. Findings revealed that female mice demonstrated more pronounced global cardiac chamber dilation during aging.

Short-term outcomes of repair vs. replacement for rheumatic mitral valve disease

open access: yesFrontiers in Cardiovascular Medicine
BackgroundThe main types of surgery for rheumatic mitral valve disease are traditional percutaneous mitral balloon valvuloplasty (PMBV), mitral valve replacement (MVR) with removal of the original valve, and valve repair with preservation of the original

The characteristics of collagen‐induced rheumatoid arthritis in macaques and the changes of heart

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The disease progression in CIA macaques was categorized into three stages: IIR (days 14–34): The indicators related to rheumatoid arthritis and the levels of immunoglobulin were all elevated. There was a small amount of joint effusion, edema and mild synovial hyperplasia. No joint swelling was observed by naked eye.

Small vesicles, big potential: A review of innovative exosome delivery and molecular mechanisms in preclinical myocardial infarction models

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This narrative review discusses animal models of exosome‐based myocardial infarction treatments. Emerging techniques aim to improve exosome stability, targeting, and bioavailability for MI treatment as drug delivery vehicles and regenerative mediators that promote myocardial regeneration. Abstract Exosomes have emerged as promising therapeutic carriers,

Identification of major congenital malformations based on healthcare databases in France: A proof‐of‐concept study using the epi‐meres nationwide mother–child register

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Besides registries, healthcare databases can provide useful information for assessing the frequency of major congenital malformations (MCMs) and investigating their risk factors, particularly medication exposures. This study aimed to assess the validity of MCMs identification based on French national, comprehensive healthcare databases ...

Balloon‐Expandable Versus Self‐Expanding Valves in Low‐Flow, Low‐Gradient Aortic Stenosis: Does Valve Type Matter?

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The optimal choice between balloon‐expandable (BE) and self‐expanding (SE) transcatheter heart valves (THVs) in patients with low‐flow low‐gradient aortic stenosis (LFLG AS) undergoing transcatheter aortic valve replacement (TAVR) remains unclear.
