Key result
Radiofrequency ablation successfully treated a rare case of atypical AVNRT in a patient with Ebstein anomaly of the tricuspid valve.
Why the study?
Atypical AVNRT is a rare cause (<2%) of SVT in patients with Ebstein anomaly of the tricuspid valve.
Case Report (n=1)
Radiofrequency ablation can successfully treat atypical AVNRT in patients with Ebstein anomaly.
May support RFA feasibility for atypical AVNRT in Ebstein anomaly; leaves open need for larger studies before broader adoption.
Accessory pathway (AP)–mediated atrioventricular re-entrant tachycardia (AVRT) is the most common form of supraventricular tachycardia (SVT) in Ebstein anomaly of the tricuspid valve (ETV). Atypical atrioventricular nodal re-entrant tachycardia (AVNRT) is a rare cause (<2%) of SVT in this patient population.1 We present a rare case atypical AVNRT in ETV that was confirmed by electrophysiology study (EPS) and successfully treated with radiofrequency ablation.
