Abstract

This is the first report demonstrating persistence and distortion of electrical activity in the left atrial appendage 5 years after endovascular occlusion with a Watchman device. Electrical conduction is impaired providing an arrhythmogenic substrate for atrial tachyarrhythmias. Localized inflammation may result in structural and electrical remodeling in these patients. (Level of Difficulty: Intermediate.).

Keywords: AF, atrial fibrillation; EI-LAA, electrical isolation of the left atrial appendage; LAA, left atrial appendage; ablation; atrial fibrillation; electrophysiology.
