Key result
Electrographic flow mapping uses fluid dynamics to reconstruct wavefronts and identify active AF sources.
Why the study?
Ablation strategies remain poorly defined for persistent AF recurrence despite intact PVI, and current advanced mapping technologies suffer from technical limitations.
Electrographic flow mapping provides a novel mathematical approach to identify and target active extra-pulmonary vein sources in persistent atrial fibrillation.
No takes yet. Share an insight, caveat, or question.
May aid targeting of extra-PV sources in persistent AF; leaves open prospective validation before clinical use.
Haines et al. (2022) conducted a review in Atrial fibrillation. Electrographic flow (EGF) mapping was evaluated. Electrographic flow mapping provides a novel method based on optical flow and fluid dynamics to reconstruct organized wavefront propagation and identify active sources in atrial fibrillation.
