Summary

The purpose of this study is to compare the effectivity and safety of atrial fibrillation ablation, in comparison to antiarrhythmic drug therapy in patients with refractory, persistent atrial fibrillation.

Clinical Details

Official title: Study of Ablation Versus antiaRrhythmic Drugs in Persistent Atrial Fibrillation

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Freedom from atrial arrhythmias, lasting more than 24 hours or requiring cardioversion.

Secondary outcome:

Freedom from atrial arrhythmias (lasting more than 30 seconds) without antiarrhythmic drugs.

Decrease in frequency and duration of atrial fibrillation or atrial flutter recurrences.

Decrease in atrial fibrillation/atrial flutter related hospital admissions

Improve in quality of life measured with standard questionary for Atrial Fibrillation: AF-QoL.

Change in need of cardioversions

Need of atrio-ventricular node ablation

Need of crossover to the other arm of the study (only when primary end point has been reached)

Need of a new intervention or ablation during blanking period

Detection of asymptomatic episodes by Reveal XT

Presence of any complications in the acute phase or during follow-up

Eligibility

Minimum age: 18 Years. Maximum age: 70 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Reduced expectancy of life (less than 12 months)

- Patient participating in another clinical study that investigates a drug or device

- Psychologically unstable patient or denies to give informed consent

- Any cause that contraindicate ablation procedure or antiarrhythmic drug
