Impaired coronary blood flow at higher heart rates during atrial fibrillation: investigation via multiscale modelling [PDF]

open access: yes, 2019
Background. Different mechanisms have been proposed to relate atrial fibrillation (AF) and coronary flow impairment, even in absence of relevant coronary artery disease (CAD). However, the underlying hemodynamics remains unclear.

Ventricular Fibrillation Is a Sign of Life

open access: yesBrazilian Journal of Cardiovascular Surgery, 2023
Ventricular fibrillation (VF) is a deadly rhythm problem. With asystole, it represents one of the most extreme emergencies that may engage vital prognosis within only few minutes if appropriated treatment is not instituted. It is learned in all medical schools worldwide that VF is not compatible with consciousness and sustained life. Moreover, at 37°C,

Early Repolarization Pattern and Idiopatic Sustained Monomorphic Ventricular Tachycardia: an Infrequent Combination

open access: yesJournal of Cardiac Arrhythmias, 2021
Malignant early repolarization as cause of sudden death has taken on great importance in recent years. It has been described as an entity capable of producing ventricular arrhythmic events, causing from episodes of syncope to sudden cardiac death ...

Clinical Outcomes in Patients With Nonobstructive, Labile, and Obstructive Hypertrophic Cardiomyopathy

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundHypertrophic cardiomyopathy (HCM) is a common inherited cardiac disease characterized by varying degrees of left ventricular outflow tract obstruction. In a large cohort, we compare the outcomes among 3 different hemodynamic groups. Methods and

Influence of cardiac tissue anisotropy on re-entrant activation in computational models of ventricular fibrillation

open access: yes, 2009
The aim of this study was to establish the role played by anisotropic diffusion in (i) the number of filaments and epicardial phase singularities that sustain ventricular fibrillation in the heart, (ii) the lifetimes of filaments and phase singularities,

Diathermy-induced Ventricular Fibrillation [PDF]

open access: yesJournal of Innovations in Cardiac Rhythm Management, 2020
Diathermy is extensively used in patients for intracardiac device implant and extraction. While diathermy helps with adequate hemostasis, it may rarely be associated with fatal dysrhythmias. We report a case of diathermy-induced ventricular fibrillation during device extraction.

Long‐Term Evaluation of Givinostat in Duchenne Muscular Dystrophy, and Natural History Comparisons

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives This ongoing, open‐label extension study is evaluating the long‐term safety, tolerability, and efficacy of givinostat, a Class I and II histone deacetylase inhibitor, in patients with Duchenne muscular dystrophy (DMD). Methods The recruited patients completed one of two prior clinical studies (one Phase 2 and one Phase 3 [EPIDYS ...

Incidence and predictors of premature ventricular complexes following catheter ablation for atrial fibrillation [PDF]

open access: yes, 2017
BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia, and previous studies have focused on the epidemiology, mechanisms and risk factors for this global disease (Ryder and Benjamin 1999). Various studies have examined the mechanism,

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

open access: yesAdvanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...
