Interference from lobe-and-disk left atrial appendage occluder affecting left superior pulmonary vein pulsed field ablation

Pulsed field ablation (PFA) employs high-voltage electroporation for tissue ablation, offering enhanced durability and minimized esophageal damage, thereby improving safety of pulmonary vein isolation.1 Electrical arcing, a possible complication of high-intensity electric field delivery, may occur when the current flows from 1 conductive point to another. The phenomenon is influenced by factors like electric field strength and tissue properties and may ultimately lead to significant temperature rise and tissue charring.
