Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Atrial Fibrillation Ablation

Group Type EXPERIMENTAL

Atrial fibrillation ablation

Intervention Type PROCEDURE

Atrial fibrillation ablation with radiofrequency, guided by 3D navigation map. Either 4mm or cooled tip-catheters will be used.

It will include, at least, pulmonary veins isolation; all other radiofrequency lines, including roof and mitral isthmus line, and complex fractioned electrograms ablation will be performed according to each Hospital protocol. Radiofrequency lines block will be tested.

Drug therapy

Group Type ACTIVE_COMPARATOR

Antiarrhythmic drug

Intervention Type DRUG

Usual drug therapy for atrial fibrillation. In patients with structural heart disease, amiodarone is recommended, while flecainide plus diltiazem or beta-blockers are encouraged in patients without structural heart diseases.
