Empirical Ablation to Prevent Sequential Purkinje System Recruitment

JACC: Case Reports, 2021
We report 3 cases (mean age 48.3 ± 11.6 years) of idiopathic ventricular fibrillation (IVF), in which a triggering premature ventricular complex leading to IVF could not be identified.

Potential Application of Pulsed Field Ablation in Ventricular Arrhythmias

Medicina, 2023
Pulsed field ablation (PFA) is a new ablative method for the therapy of arrhythmia. Recent preclinical and clinical studies have already demonstrated the feasibility and safety of PFA for the treatment of atrial fibrillation (AF).

Diathermy-induced Ventricular Fibrillation [PDF]

Journal 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.

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

Journal 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

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

Advanced 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 ...

Discordant Alternans as a Mechanism for Initiation of Ventricular Fibrillation In Vitro

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Ventricular tachyarrhythmias are often preceded by short sequences of premature ventricular complexes. In a previous study, a restitution‐based computational model predicted which sequences of stimulated premature complexes were most likely to

PFKM‐Driven Lactate Overproduction Promotes Atrial Fibrillation via Triggering Cardiac Fibroblasts Histone Lactylation

Advanced Science, EarlyView.
The upregulation of PFKM activates glycolysis, thereby enhancing lactate production in atrial tissue. Atrial lactate accumulation promotes global lactylation and H3K18 lactylation in atrial fibroblasts. P300‐mediated H3K18 lactylation up‐regulates TGF‐β1 transcription, leading to fibroblast activation and thereby contributing to atrial fibrosis.

Novel SCN5A mutation associated with idiopathic ventricular fibrillation due to subclinical Brugada syndrome

Cardiogenetics, 2011
Idiopathic ventricular fibrillation can be caused by subclinical channelopathies such as Brugada syndrome. Our objective is to study the clinical behaviour of a new SCN5A mutation found in a woman with idiopathic ventricular fibrillation.

Management of sudden cardiac death in cardiac sarcoidosis using the wearable cardioverter defibrillator. [PDF]

PLoS ONE, 2018
Patients with cardiac sarcoidosis are at increased risk of ventricular tachycardia/fibrillation.We tested the hypothesis that the wearable cardioverter defibrillator can be used to mitigate the risk of sudden cardiac death among cardiac sarcoidosis ...
