Standards for heart valve surgery in a ‘Heart Valve Centre of Excellence’ [PDF]

Open Heart, 2015
Surgical centres of excellence should include multidisciplinary teams with specialist expertise in imaging, clinical assessment and surgery for patients with heart valve disease. There should be structured training programmes for the staff involved in the periprocedural care of the patient and these should be overseen by national or international ...

Fluid-structure interaction simulation of prosthetic aortic valves : comparison between immersed boundary and arbitrary Lagrangian-Eulerian techniques for the mesh representation [PDF]

, 2016
In recent years the role of FSI (fluid-structure interaction) simulations in the analysis of the fluid-mechanics of heart valves is becoming more and more important, being able to capture the interaction between the blood and both the surrounding ...

Comparative Anatomy of Mitral and Tricuspid Valve: What Can the Interventionlist Learn From the Surgeon

Frontiers in Cardiovascular Medicine, 2018
Transcatheter valve interventions on the mitral and tricuspid valves entail increasing complexity. Part of the knowledge that has been generated during the development of mitral devices can be transferred to the tricuspid valve (TV).

The Endocardium and Heart Valves

Cold Spring Harbor Perspectives in Biology, 2020
Endocardial cells are specialized endothelial cells that, during embryogenesis, form a lining on the inside of the developing heart, which is maintained throughout life. Endocardial cells are an essential source for several lineages of the cardiovascular system including coronary endothelium, endocardial cushion mesenchyme, cardiomyocytes, mural cells,

Blocking the voltage‐gated sodium channel hNav1.5 as a novel pH‐dependent mechanism of action for tamoxifen

FEBS Open Bio, EarlyView.
Patch‐clamp recordings revealed that tamoxifen inhibits voltage‐gated sodium channels, especially under acidic conditions, both common in metastatic cancer cells. These effects may explain certain antitumor properties of tamoxifen, highlighting a novel mechanism of action beyond its known endocrine effects.

Mean Aortic pressure gradient and global longitudinal strain recovery after transcatheter aortic valve replacement – A retrospective analysis

Hellenic Journal of Cardiology, 2018
Background: Global longitudinal strain (GLS) has incremental value in assessing left ventricular (LV) function in severe aortic stenosis and is related to clinical outcome after transcatheter aortic valve replacement (TAVR).

Aortic valve cusp repair does not affect durability of modified aortic valve reimplantation for tricuspid aortic valvesCentral MessagePerspective

JTCVS Open, 2023
Objective: During aortic valve reimplantation, cusp repair may be needed to produce a competent valve. We investigated whether the need for aortic valve cusp repair affects aortic valve reimplantation durability.

Microphysiological Glomerular Filtration Barriers: Current Insights, Innovations, and Future Applications

Advanced Biology, EarlyView.
The glomerular filtration barrier (GFB) is the first step of blood filtration by the kidneys. The concerning increase of kidney diseases makes the development of new models essential. In this context, microphysiological glomerular filtration barriers focus on closely reproducing the physiological architecture of the in vivo GFB: podocytes, glomerular ...

A Misleading Left Atrial Appendage

JACC: Case Reports, 2023
Left atrial appendage collapse is a relatively unusual echocardiographic finding. Although in post-cardiac surgery patients it may be an early sign of cardiac tamponade, and pericardiocentesis should be discussed, a conservative approach may be followed ...

Electronic Control System for Optimized Resonance Operation of Dielectric Elastomer Pumps through Self‐Sensing

Advanced Engineering Materials, EarlyView.
A powerful electronic control system enables a dielectric elastomer pump to operate at resonance, matching conventional pump performance. Using self‐sensing to reconstruct load pressure dynamically, the adaptive control adjusts resonance frequency accordingly.
