Key result
Radiofrequency catheter ablation successfully eliminates accessory pathway-mediated AVRT in an infant without causing AV block.
Why the study?
Right anteroseptal accessory pathway causing atrioventricular reentry tachycardia is rare and carries a high risk of atrioventricular block during ablation.
Case Report (n=1)
No
Radiofrequency catheter ablation can be safely and effectively performed for right anteroseptal accessory pathways even in small infants.
Minimal ablation may safely eliminate rare infant anteroseptal pathways without nodal injury; leaves open confirmation in larger series.

Fujita et al. (2012) conducted a case report in Refractory Atrioventricular Reentry Tachycardia (AVRT) (n=1). Radiofrequency catheter ablation was evaluated on Elimination of V-A conduction and non-inducibility of AVRT. Radiofrequency catheter ablation successfully eliminated V-A conduction and prevented the induction of atrioventricular reentry tachycardia in a 10-month-old infant without causing AV block.
