A Novel Computational Platform to Analyze Left Atrial Voltage Acquired from Electroanatomic Mapping

Atrial cardiomyopathy represents structural and electrophysiologic abnormalities associated with atrial fibrillation (AF). Fibrosis, visualized with late gadolinium enhancement on cardiac magnetic resonance imaging (MRI), is associated with low voltage on electroanatomic mapping1, and ablation outcomes 2. Voltage data is readily acquired in an ablation procedure but comparing voltage between subjects is complicated by variation in atrial size and orientation. A computational analysis platform is needed that can automatically align and scale atria of disparate sizes and orientation to permit comparisons in pre-specified regions of interest to further understanding of left atrial voltage distribution.
