Association of extra‐pulmonary vein triggers with low‐voltage area and clinical recurrence in patients with atrial fibrillation undergoing catheter ablation

Background and Objectives Although extra‐pulmonary vein (PV) triggers (ExPVTs) play a role in atrial fibrillation (AF) recurrence after catheter ablation (AFCA), the mechanism is unknown. We explored whether the locations of ExPVTs were associated with low‐voltage scar areas (LVAs). Methods Among 22...

Description
Summary:Background and Objectives Although extra‐pulmonary vein (PV) triggers (ExPVTs) play a role in atrial fibrillation (AF) recurrence after catheter ablation (AFCA), the mechanism is unknown. We explored whether the locations of ExPVTs were associated with low‐voltage scar areas (LVAs). Methods Among 2255 consecutive patients who underwent a de novo AFCA, 1696 (male 72.1%, median 60 years old, paroxysmal 64.7%) were included who underwent isoproterenol provocation and voltage mapping of the left atrium (LA) during their procedures. We investigated the associations between ExPVTs and their mean LA voltage and colocalization of ExPVTs within LVAs (
