Spatial Relationships between the Pulmonary Veins and Sites of Complex Fractionated Atrial Electrograms During Atrial Fibrillation

Background: Pulmonary vein (PV) isolation is used for the treatment of atrial fibrillation (AF). Complex fractionated atrial electrogram (CFAE) mapping has been introduced to guide AF ablation. However, the spatial relationship between PV and CFAE is not well defined. Methods and Results: The study...

Description
Summary:Background: Pulmonary vein (PV) isolation is used for the treatment of atrial fibrillation (AF). Complex fractionated atrial electrogram (CFAE) mapping has been introduced to guide AF ablation. However, the spatial relationship between PV and CFAE is not well defined. Methods and Results: The study included 21 patients (mean age 57 ± 11 years, 17 men, 14 paroxysmal, two persistent, and five long‐standing persistent AF) referred for PV isolation. Electrograms were sampled for 8 seconds at each site during stable AF (13 induced). High‐frequency was defined as
