Successful ablation of a posterolateral right accessorial pathway eliminated Wolff-Parkinson-White syndrome and paroxysms of atrial fibrillation in a 32-year-old female with Ebstein's anomaly.
Case Report (n=1)
Ebstein's anomaly with an accessory pathway can cause paroxysmal atrial fibrillation in young patients, which is treatable with successful ablation.

Ablation may eliminate AF in Ebstein's anomaly with accessory pathways; leaves open whether findings extend beyond single cases.
BACKGROUND: Ebstein's anomaly is characterized by a displacement of the tricuspid valve toward apex, because of anomalous attachment of the tricuspid leaflets. There are type B of Wolff-Parkinson-White (WPW) syndrome and paroxysmal arrhythmias in more than a half of all patients. CASE REPORT: We presented a female, 32-year old, with frequent paroxysms of atrial fibrillation. After conversion of rhythm an ECG showed WPW syndrome. Echocardiographic examination discovered normal size of the left cardiac chambers with paradoxical ventricular septal motion. The right ventricle was very small because of its atrialization. The origin of the tricuspid valve was 20 mm closer to apex of the right ventricle than the origin of the mitral valve. Electrophysiological examination showed a posterolateral right accesorial pathway. Atrial fibrillation was induced very easily in electrophysiological laboratory and a successful ablation of accessorial pathway was made. There were no WPW syndrome and paroxysms of atrial fibrillation after that. CONCLUSION: Ebstein's anomaly is one of the reasons of paroxysmal atrial fibrillation, especially in young persons with WPW syndrome.

Damjanović et al. (2008) conducted a case report in Ebstein's anomaly and paroxysmal atrial fibrillation (n=1). Ablation of accessorial pathway was evaluated on Elimination of WPW syndrome and paroxysms of atrial fibrillation. Successful ablation of a posterolateral right accessorial pathway eliminated Wolff-Parkinson-White syndrome and paroxysms of atrial fibrillation in a 32-year-old female with Ebstein's anomaly.
