In this episode, Jeremy Moore, MD, MS, Associate Editor of JACC: Clinical Electrophysiology, reviews a study showing that adults with Ebstein anomaly face a high lifetime risk of atrial arrhythmias, with more than half developing one by age 60. The most common arrhythmias were intra-atrial re-entrant and focal atrial tachycardias, which were more frequent than atrial fibrillation. Older age, prior cardiac surgery, significant tricuspid valve leakage, and severe right ventricular dysfunction were key risk factors, underscoring the need for lifelong specialized follow-up.
