Cryoballoon Versus Radiofrequency Ablation for Persistent Atrial Fibrillation: Meta‐Analysis of Randomized Trials

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Pulmonary vein isolation (PVI) alone achieves modest arrhythmia freedom in persistent atrial fibrillation (PeAF). Cryoballoon ablation (CBA) offers a single‐shot alternative to radiofrequency ablation (RFA) that streamlines procedural workflow.

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Pulmonary Vein Isolation Without Left Atrial Mapping

Indian Pacing and Electrophysiology Journal, 2007
Background: One of the crucial points during in most approaches developed for ablation of atrial fibrillation (AF) is the ability to identify the pulmonary vein (PVs) and to accurately locate their ostia.

The utility of 24-h electrocardiogram recordings for the prediction of a sufficient number of premature ventricular complexes and mapping strategy during catheter ablation

Frontiers in Cardiovascular Medicine
Background and aimsAn insufficient number of premature ventricular complexes (PVCs) during catheter ablation (CA) may prohibit adequate mapping of the site of origin. Parameters to predict this situation have not been established.

Catheter-based intramyocardial delivery (NavX) of adenovirus achieves safe and accurate gene transfer in pigs.

PLoS ONE, 2013
BackgroundHepatocyte growth factor (HGF) is one of the major angiogenic factors being studied for the treatment of ischemic heart diseases. Our previous study demonstrated adenovirus-HGF was effective in myocardial ischemia models.

A new approach to an old disease: Ageing, arrhythmogenic substrate and the role of risk‐factor modification in atrial fibrillation

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) prevalence rises sharply with age due to two independent mechanisms. Ageing produces irreversible arrhythmogenic substrate changes through progressive fibrosis, cellular senescence and mitochondrial dysfunction, while modifiable risk factors such as obesity, hypertension, sleep apnoea, diabetes and alcohol use promote ...

High-density mapping in catheter ablation of ventricular arrhythmias

Cardiologia Hungarica
Catheter ablation of ventricular arrhythmias has evolved in recent years with the development and improvement of various technologies, most notably electroanatomical navigators and multielectrode catheters that allow for high-density mapping.

The multicellular environment of the re‐entrant circuit in post‐myocardial infarction ventricular tachycardia: Beyond fibrosis

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the temporal evolution of the post‐myocardial infarction substrate leading to ventricular tachycardia. Acute ischaemic injury initiates metabolic and electrophysiological disruption, followed by progressive inflammatory, fibrotic and structural remodelling within the infarct border zone.

A case of premature ventricular contractions originating from the papillary muscle in the right ventricle

Journal of Arrhythmia, 2014
A 45-year-old man with premature ventricular contractions (PVCs) underwent electrophysiological studies. Activation mapping using a noncontact electroanatomical mapping system indicated that the septal mid-apical region in the right ventricle was ...

Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).
