Key result
A left lateral accessory pathway resistant to traditional endocardial ablation was successfully eliminated by radiofrequency ablation via the intracoronary sinus approach.
Why the study?
Does radiofrequency ablation via the intracoronary sinus approach eliminate a left lateral accessory pathway resistant to traditional endocardial ablation in a patient with drug-resistant supraventricular tachycardia?

Does radiofrequency ablation via the intracoronary sinus approach eliminate a left lateral accessory pathway resistant to traditional endocardial ablation in a patient with drug-resistant supraventricular tachycardia?
Radiofrequency ablation via the intracoronary sinus approach can successfully eliminate a left lateral accessory pathway that is resistant to traditional endocardial ablation.
A 41-year-old male was presented with drug-resistant supraventricular tachycardia. Electrophysiological study confirmed that the supraventricular tachycardia was caused by dual atrioventricular nodal pathways and a left lateral accessory pathway (AP). The left lateral AP was resistant to traditional endocardial ablation, but was successfully eliminated by radiofrequency ablation via the intracoronary sinus approach.

June Namgung (2013) conducted a case report in Drug-resistant supraventricular tachycardia (AVRT and atypical AVNRT) (n=1). Radiofrequency ablation via intracoronary sinus approach vs. Conventional endocardial approach (transseptal) was evaluated on Elimination of accessory pathway and slow pathway. A left lateral accessory pathway resistant to traditional endocardial ablation was successfully eliminated by radiofrequency ablation via the intracoronary sinus approach.
