Radial Ablation for the Control of Persistent Atrial Fibrillation — ARTIST  

Persistent Atrial Fibrillation Clinical Trial

Official title:
Radial Ablation for the Control of Persistent Atrial Fibrillation (Ablación Radial Para conTrol de la fibrilación Auricular persISTtente)

Clinical Trial Summary

The protocol aims to evaluate the efficacy of the radial ablation technique of the maintenance mechanisms in persistent atrial fibrillation compared to the isolation of the pulmonary veins evaluating the atrial fibrillation burden during one year follow-up.

Clinical Trial Description

Atrial fibrillation is the most common arrhythmia in clinical practice, and its treatment still remains suboptimal. Electrical isolation of the pulmonary veins with radiofrequency ablation or cryoablation is the standard therapy when antiarrhythmic drugs or electrical cardioversion is not successful. However, recurrence after catheter ablation worsens in persistent and permanent atrial fibrillation patients. Recently, rotational activity electrogram patterns of self-sustained electrical activity found in the atria have been proposed as the responsible mechanism for the maintenance of atrial fibrillation. The investigators devised a controlled, multicentric, prospective, not blinded, and randomized clinical trial with the aim of comparing pulmonary vein catheter ablation versus radial ablation of sites exhibiting rotational activity in patients with persistent atrial fibrillation. Radial ablation consists of the ablation of the rotational activity sites and an additional ablation line connecting the rotation site with the circumferential ablation line of the pulmonary veins. Besides, subanalysis ARTIST-Gender and ARTIST-HF will be performed. ARTIST-Gender will compare the same outcomes and analysis of the patient cohort but according to the gender of the patient, and ARTIST-HF will sub-divide the analysis with respect to heart failure present in the enrolled patients' cohort. ;
