Abstract

A 14-year-old male underwent an electrophysiology procedure for recurrent left atrial tachycardia (AT). A prior attempt at ablation was unsuccessful. After transeptal catheterization, an electroanatomic map of the left atrium (LA) and left atrial appendage (LAA) was created during AT. The mechanism of the tachycardia did not appear to be macroreentrant. The origin of the tachycardia appeared to be the left atrial appendage. However, the electroanatomic map showed a relatively broad area of early activation and failed to identify a clear focus of origin. What additional strategy could be used to increase the likelihood of successful ablation?
