Aims Force–Time Integral (FTI) is commonly used as a marker of ablation lesion quality
during pulmonary vein isolation (PVI), but does not incorporate power. Ablation Index (AI) is …

Background Catheter ablation for persistent atrial fibrillation (AF) is associated with less
favorable outcomes than for paroxysmal AF. Substrate modification is often added to …

Aims Late recovery of ablated tissue leading to reconnection of pulmonary veins remains
common following radiofrequency catheter ablation for AF. Ablation Index (AI), a novel …

Background—Current guidelines recommend a 3-month blanking period after pulmonary
vein isolation (PVI) as early recurrence of atrial tachyarrhythmia (ERAT) may be due to …

Introduction Radiofrequency catheter ablation is a cornerstone of treatment for many cardiac
arrhythmias. Progression in three‐dimensional mapping and contact‐force sensing …

Objectives: The goal of this study was to determine whether a strategy of early re-isolation of
pulmonary vein (PV) reconnection in all patients, regardless of symptoms, would reduce the …

Objectives: The aim of this study was to compare the electrophysiologic substrate in
ischemic cardiomyopathy (ICM) patients with and without sustained monomorphic …

Background Atrial fibrillation (AF) ablation is a complex procedure, generally requiring at
least one overnight hospital stay. We investigated the safety and feasibility of early …

Background A large number of SCN5A variants have been reported to underlie Brugada
syndrome (BrS). However, the evidence supporting individual variants is highly …

Background More advanced atrial fibrillation (AF) is associated with lower success rates
after pulmonary vein isolation (PVI), and the optimal ablation strategy is uncertain …
