Summary
This is a cohort study to evaluate algorithms for mapping atrial fibrillation by mapping atrial structure and mapping electrical activity to detect focal and rotational activity.
Description
In this study, the investigators will compare mapping approaches for atrial fibrillation ablation.
First, investigators will compare approaches to map atrial structure from collected computed tomography (CT) scans or magnetic resonance imaging (MRI) scans acquired routinely in patients undergoing ablation for atrial fibrillation. Imaging will be acquired from a variety of clinically approved
Second, investigators will compare approaches to analyze electrograms collected routinely at clinical electrophysiology study (EPS) in patients undergoing ablation for atrial fibrillation. Electrograms will be recorded from a variety of clinically approved catheters under standard of care conditions, and will be analyzed to better understand the mechanisms for atrial fibrillation and its relationship to outcomes.
The investigators anticipate analyzing data from 200 patients through December 2017.
