Catheter ablation of atrial fibrillation (AF) is an established therapy that reduces AF burden,
improves quality of life, and reduces the risks of cardiovascular outcomes. Although there …

Aims REDO-FIRM evaluated safety and effectiveness of conventional vs. focal impulse and
rotor modulation (FIRM)-guided ablation of recurrent persistent or paroxysmal atrial …

Introduction The second-generation cryoballoon (CB) has emerged in the last decade as an
effective treatment for atrial fibrillation (AF). This study sought to analyze the rate of PV …

Introduction Cather ablation (CA) is a well‐recognized treatment alternative for atrial
fibrillation (AF) patients despite more than 20% ablation‐treated patients suffering from AF …

Background The second-generation cryoballoon (CB) has proven to be a highly effective
ablative strategy in patients with symptomatic atrial fibrillation (AF). This study sought to …

Background There are no standard mapping approaches for patients with persistent atrial
fibrillation (PeAF), particularly after failed prior catheter ablation (CA). In this study, we …

Atrial fibrillation (AF) often requires invasive treatment by ablation to decrease symptom
burden. The pulmonary veins (PV) are thought to trigger paroxysms of AF, and ablative PV …

Background The role of anti-arrhythmic drugs (AADs) in recurrent atrial fibrillation (AF) after
catheter ablation (CA) is not fully understood. The aim of this study was to explore the effects …

Introduction Approximately 18% of patients with atrial fibrillation (AF) undergo a repeat
ablation within 12 months after their index ablation. Despite the high prevalence …

Background The tissue response viewer (TRV) is a novel marker for ablation lesion quality
that aims to classify lesions into transmural or nontransmural lesions (high or low dielectric …
