Filter by:The purpose of this study it to learn whether pulmonary vein isolation (PVI) along with ablation of the posterior left atrial wall (PLAW) will reduce the likelihood of atrial fibrillation (AF) recurrence in patients with persistent or long-standing persistent AF one year after an ablation procedure in comparison to a PVI ablation procedure, alone. The investigator hypothesizes that the combination of PVI plus PLAW isolation will result in a reduction in recurrence of atrial arrhythmias at one year after ablation.
The purpose of this feasibility study is to further explore characteristics of ablation targets identified by CARTOFINDER 4D LAT Algorithm in subjects with persistent atrial fibrillation and to assess the acute outcome of CARTOFINDER Guided Ablation in terms of the termination of atrial fibrillation to either Normal Sinus Rhythm or Atrial Tachycardia.
This study will compare efficacy and safety of pulmonary vein isolation using a cryoballoon catheter versus a radiofrequency ablation with a contact force sensing catheter for treatment of patients with persistent or longstanding persistent atrial fibrillation.
The purpose of this trial is to assess acute safety and performance of the Multi-electrode Linear Type Catheter in conjunction with generator software V2.4.0 or above when used for the treatment of Persistent Atrial Fibrillation.
We aimed to assess the benefit of epicardial mapping and ablation in patients with recurred atrial tachyarrhythmias after single procedure for atrial fibrillation. We hypothesize that both endocardial and epicardial approach is superior to only endocardial approach with regards to clinical recurrence. Participants are randomized into a hybrid approach or an endocardial approach.
A prospective, single-arm, multi-center, multi-national, non-randomized, post-market study designed to provide clinical data regarding the use of the AcQMap™ System in the ablation of persistent atrial fibrillation. (CL-AF-002 - EU) A prospective, single-arm, multi-center, multi-national non-randomized study designed to provide clinical data regarding the use of the AcQMap™ System in the ablation of persistent atrial fibrillation. (CL-AF-001 - Canadian)
A prospective, multicenter, randomized study to assess the safety and effectiveness of FIRM-guided procedures in conventional "redo" RF ablation procedures for the treatment of persistent and paroxysmal atrial fibrillation.
This study evaluates if the exclusion of left atrial low voltage areas / scars by ablation lines in addition to pulmonary vein isolation may improve the outcome in patients with persistent atrial fibrillation in comparison to stand alone pulmonary vein isolation.
This is a prospective randomized controlled trial that compares the conventional stepwise approach with a new sequential substrate ablation approach for persistent atrial fibrillation.
In this study, the investigators aim to identify and characterize, by means of an EnSite Velocity Research Software, the electrophysiological characteristics of substrates that sustain AF in patients with persistent AF and to test whether ablation of such patient-specific substrates might improve the acute and long-term success of conventional catheter ablation therapy.
