Interference from Lobe-and-Disc 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 PVI safety (1). Electrical arcing is a possible complication of high-intensity electric field delivery, which may occur when the current flows from one 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.
