Targeting the left atrial posterior wall during pulsed field ablation fails to improve outcomes

Example of a left atrial posterior wall (LAPW) pulmonary vein isolation (PVI) to better treat persistent atrial fibrillation (AFib) using the Abbott electromapping system.

An example of a left atrial posterior wall (LAPW) ablation procedure where there are connecting lines between the two pulmonary vein isolation (PVI) ablations to better isolate signals causing persistent AFib.

Researchers explored the potential of an alternate way to perform PFA on patients with persistent AFib, presenting their findings live at AF Symposium 2024 in Boston.
