There are limited data comparing radiofrequency catheter ablation with antiarrhythmic drug therapy as first-line treatment in patients paroxysmal atrial fibrillation.We randomly assigned 294 fibrillation and no history of use to an initial strategy either (146 patients) or class IC III agents (148 patients). Follow-up included 7-day Holter-monitor recording at 3, 6, 12, 18, 24 months. Primary end points were the cumulative per-visit burden (i.e., percentage time on recordings). Analyses...

Abstract Aims Pulsed field ablation (PFA) is a novel atrial fibrillation (AF) modality that has demonstrated preferential tissue ablation, including no oesophageal damage, in first-in-human clinical trials. In the MANIFEST-PF survey, we investigated ‘real world’ performance of only approved PFA catheter, acute effectiveness and safety—in particular, rare effects other unforeseen PFA-related complications. Methods results This retrospective survey included all 24 centres using pentaspline...

Abstract Pulsed field ablation (PFA) is an emerging technology for the treatment of atrial fibrillation (AF), which pre-clinical and early-stage clinical data are suggestive some degree preferentiality to myocardial tissue without damage adjacent structures. Here in MANIFEST-17K study we assessed safety PFA by studying post-approval use this modality. Of 116 centers performing with a pentaspline catheter, were received from 106 (91.4% participation) regarding 17,642 patients undergoing (mean...

Patients undergoing catheter ablation for atrial fibrillation (AF) often experience recurrent arrhythmias within the first few months post-ablation. We aimed to investigate whether short-term use of amiodarone prevent early following radiofrequency AF could reduce later recurrence. In a two-centre, randomized, double-blind, placebo-controlled study, we randomized total 212 patients ablation. were stratified according type (paroxysmal/persistent) and history previous randomly assigned 8 weeks...

To investigate the long-term risk of thromboembolism and serious bleeding associated with oral anticoagulation (OAC) therapy beyond 3 months after radiofrequency ablation (RFA) atrial fibrillation (AF). Linking Danish administrative registries, 4050 patients undergoing first-time RFA (2000–11) were identified. Risk according to OAC analysed by incidence rates (presented per 100 person-years) Cox proportional-hazard models. The median age was 59.5 years (interquartile range, IQR: 52.8–65.2);...

During the last decade, ablation has increasingly been used in rhythm control management of patients with atrial fibrillation (AF). Over time, experience and techniques have improved indications for expanded. The purpose this study was to investigate whether recurrence rate AF following during decade.Through Danish nationwide registers, all first-time ablation, between 2005 2014 Denmark were identified.

The Medical ANtiarrhythmic Treatment or Radiofrequency Ablation in Paroxysmal Atrial Fibrillation (MANTRA-PAF) trial assessed the long-term efficacy of an initial strategy radiofrequency ablation (RFA) vs. antiarrhythmic drug therapy (AAD) as first-line treatment for patients with PAF. In this substudy, we evaluated effect these modalities on Health-Related Quality Life (HRQoL) and symptom burden at 12 24 months.During study period, 294 were enrolled MANTRA-PAF randomized to receive AAD (N =...

Despite improvement in treatment strategies of atrial fibrillation (AF), a considerable number patients still experience recurrence tachyarrhythmia (ATA) following catheter ablation (CA). This study aimed to investigate the prognostic value left (LA) deformation analysis large group undergoing CA for AF.This included 678 with AF. Echocardiography including two-dimensional speckle tracking echocardiography (2DSTE) was performed all prior CA. Logistic regression used assess association between...

Guidelines recommend prioritizing treatment with antiarrhythmic drugs before referral of patients atrial fibrillation to ablation, delaying a potential subsequent ablation. However, ablation may affect outcomes. We sought investigate the impact duration from diagnosis on risk recurrence and adverse events.
