Brief Summary

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

To evaluate a new AF Substrate mapping method based on automatic high density CFAE detection with a multipolar catheter (Pentaray) and the " SCI 30-40 " setting of CARTO CFAE algorithm.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is observational :

This substrate ablation method is performed routinely in the centers involved in the study so, patients were not assigned by the investigators to undergo a specific procedure because of the study, in all cases patient would have beneficiate from this substrate mapping ablation method.

We assessed procedural and follow up outcomes of this subatrate ablation group and compared them with an historical control group undergoing conventional ablation.

Studied

Between September 2013 and July 2014, 105 patients were enrolled in 3 centers performing routinely Atrial Fibrillation ablation guided by spatio-temporal electrogram dispersion without pulmonary vein Isolation

Routine substrate ablation without pulmonary vein Isolation

Intervention Type PROCEDURE

Control

The validation set included a cohort of 47 patients with symptomatic drug-refractory AF who underwent ablation using a conventional approach.

Routine conventional ablation with pulmonary vein Isolation
