Abstract

Purpose of Review

Despite enthusiasm for catheter ablation of atrial fibrillation, procedural outcomes are less robust when compared to other atrial arrhythmias

Recent Findings

Adverse atrial remodeling is associated with both the perpetuation of atrial fibrillation as well as decreased responsiveness to restorative therapies. However, characterization of remodeling has historically relied on demographic factors and echocardiographic imaging which provide inadequate insight into the pattern and distribution of atrial fibrosis. Advancements in electroanatomical mapping allow rapid collection of dense three-dimensional maps that display both structural and functional datasets.

Summary

The purpose of this review is to discuss contemporary studies that seek to determine bipolar electrogram characteristics in patients with and without atrial fibrillation. We will also review studies that use electrogram data to guide substrate-based ablation in AF patients.
