Leadless Pacemaker Implantation in High‐Risk Patients: Real‐World Outcomes From a Multicenter Israeli Registry

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Transvenous pacemakers are effective but carry significant short‐ and long‐term complications. Leadless pacemakers were developed to overcome these limitations, however, data in high‐risk patients ineligible for transvenous systems remain limited.

When surgery is not an option: case report of transcatheter valve-in-valve replacement for mitral valve dysfunction

The Egyptian Heart Journal
Background Heart valve diseases affect over 100 million people globally, with mitral regurgitation being the most common in developed countries. Bioprosthetic heart valves, frequently used for replacement, typically last 10–15 years before degeneration ...

Surgery for rheumatic mitral valve disease in sub-saharan African countries: why valve repair is still the best surgical option

The Pan African Medical Journal, 2016
Rheumatic valve disease, a consequence of acute rheumatic fever, remains endemic in developing countries in the sub-Saharan region where it is the leading cause of heart failure and cardiovascular death, involving predominantly a young population.

Haemodynamic effects of selective venoconstriction with centhaquine in spontaneously breathing patients with mixed hypovolaemic‐vasodilatory shock

Experimental Physiology, EarlyView.
Abstract Circulatory shock remains difficult to manage because fluid resuscitation and catecholamines may exacerbate vascular dysfunction and tissue hypoperfusion. This prospective physiological analysis, embedded within a multicentre phase IV study, examined whether selectively targeting the venous circulation with centhaquine improves circulatory ...

The impact of biological sex and stroke volume constituents on heterogeneity in the Q̇$\dot{Q}$–V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$ relationship and skeletal muscle saturation during cycling

Experimental Physiology, EarlyView.
Abstract Interindividual variability in the cardiac output (Q̇$\dot{Q}$) to the rate of oxygen consumption (V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$) slope (Q̇$\dot{Q}$–V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$) in healthy males is related to stroke volume (SV); however, the impact of differences in left ventricular (LV) structure and function as well as ...

Economic Burden of Inpatient Care for Mitral Regurgitation in Maryland

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Mitral regurgitation (MR) is the most common valvular disease in the United States and increases the risk of death and hospitalization. The economic burden of MR in the United States is not known.

An eikonal model with re‐excitability for fast simulations in cardiac electrophysiology

The Journal of Physiology, EarlyView.
Abstract figure legend Restitution properties obtained from cable‐equation simulations and anisotropic remeshing informed by local fibre orientation are combined in an eikonal model with re‐excitability. The resulting reduced electrophysiology model enables efficient simulations of recurrent activation patterns, here illustrated by atrial re‐entry ...

Enhancing stroke risk stratification in atrial fibrillation through non‐Newtonian blood modelling and Gaussian process emulation

The Journal of Physiology, EarlyView.
Abstract figure legend Non‐Newtonian modelling and GPEs for stroke risk in atrial fibrilation patients. Abstract Atrial fibrillation (AF) is the most common heart arrhythmia, linked to a five‐fold increase in stroke risk. The left atrial appendage (LAA), prone to blood stasis, is a common thrombus formation site in AF patients.
