Unintended Electrical Isolation of the Left Atrial Appendage due to Anatomical Misidentification During Pulsed-Field Ablation: A Case Report.

ABSTRACT: During pulsed-field ablation, unintended left atrial appendage isolation occurred due to anatomical misidentification with the left superior pulmonary vein. Left atrial appendage potentials improved after 1 month. This case highlights procedural tips to avoid this complication and emphasizes post-procedural monitoring and management strategies.
