Background—Catheter ablation of atrial fibrillation (AFCA) is an established therapeutic
option for rhythm control in symptomatic patients. Its efficacy and safety among patients with …

Objective To investigate whether catheter ablation of atrial fibrillation (AF) reduces stroke
rate or mortality. Methods An international multicentre registry was compiled from seven …

Atrial fibrillation (AF) and heart failure (HF) are evolving epidemics, together responsible for
substantial human suffering and health-care expenditure. Ageing, improved cardiovascular …

Background—Restoring sinus rhythm in patients with heart failure (HF) and atrial fibrillation
(AF) may improve left ventricular (LV) function and HF symptoms. We sought to compare the …

Background—Atrial stretch causes remodeling that predisposes to atrial fibrillation. We
tested the hypothesis that peaks in left atrial (LA) wall stress are associated with focal …

The CRYO Versus RF Trial Introduction Catheter ablation of paroxysmal AF using the
Cryoballoon (CRYO) has yielded similar success rates to conventional wide encirclement …

Objectives The goal of this study was to develop a risk score model for patients with Brugada
syndrome (BrS). Background Risk stratification in BrS is a significant challenge due to the …

Background National electronic health records (EHR) are increasingly used for research but
identifying disease cases is challenging due to differences in information captured between …

Objectives: This study sought to use a novel panoramic mapping system (CARTOFINDER)
to detect and characterize drivers in persistent atrial fibrillation (AF). Background …

Background Pulmonary vein isolation (PVI) using high power delivered by SmartTouch
Surround Flow (STSF) catheters guided by ablation index (AI) was evaluated in a …
