Substrate Ablation Guided by High Density Mapping in Atrial Fibrillation

Substrate Ablation Guided by Automatic High Density Mapping for the Treatment of Atrial Fibrillation

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.

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.

Inclusion Criteria:

• Patient from 18 to 85, with AF* (paroxysmal, and persistent AF) and indication of AF ablation (including redos)* *In accordance with the recommendation of European Society of Cardiology (2010).

Exclusion Criteria:

• organized atrial activity (Atrial tachycardia or Flutter)
