Transcatheter ablation of incessant ectopic atrial tachycardia in a patient with intracardiac rhabdomyomas

Abstract

We report the case of an adolescent with incessant ectopic atrial tachycardia (EAT) originating from a rhabdomyoma located on the posterior wall of the right atrium, complicated by tachycardiomyopathy. The patient underwent a combined endocardial and epicardial ablation procedure in the electrophysiology laboratory. The intervention resulted in both short- and medium-term success, with resolution of ventricular dysfunction and elimination of the arrhythmia confirmed at the 3-month follow-up.
