Left Ventricular wall Thickness and Decrement Evoked Potentials in Ablation of Ischemic Ventricular Tachycardia

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Preprocedural imaging can improve the success rate of ventricular tachycardia (VT) ablation. Left ventricular wall thickness (LVWT) measured by cardiac computed tomography (CT) can be used to identify infarct regions. We sought to determine whether an association exists between left ventricular wall thickness (LVWT) as obtained ...

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.

Segmental Snare Traction Technique for Helix‐Fixed Leadless Pacemaker Implantation Across a Repaired Tricuspid Annulus

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Helix‐fixed leadless pacemaker delivery can be challenging after tricuspid annuloplasty with a rigid ring. An 80‐year‐old woman with prior mitral valve repair, tricuspid annuloplasty (26‐mm MC ring), and Maze III surgery presented with syncope due to atrial fibrillation with a slow ventricular response. Standard maneuvers failed to advance the

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.

Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

Experimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

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 ...

Late Presentation of Recurrent Monomorphic Ventricular Tachycardia following Minimally Invasive Mitral Valve Repair due to Epicardial Injury

Case Reports in Cardiology, 2014
We report a 73-year-old male with late onset monomorphic ventricular tachycardia following mitral valve repair (MVR). Typically, injury to epicardial arteries following mitral valve repair/replacement presents immediately as ventricular tachycardia ...

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.
