Key result
Radiofrequency catheter ablation using low-power current successfully treated a parahisian accessory pathway in a 32-year-old man without causing complete atrioventricular block.
Why the study?
Does low-power radiofrequency catheter ablation safely eliminate pre-excitation in a patient with a parahisian accessory pathway without causing complete AV block?

Does low-power radiofrequency catheter ablation safely eliminate pre-excitation in a patient with a parahisian accessory pathway without causing complete AV block?
Low-power radiofrequency catheter ablation can successfully treat parahisian accessory pathways while minimizing the high risk of complete atrioventricular block.
May reduce AV block risk in parahisian ablation; leaves open need for controlled studies before adoption.
Radiofrequency catheter ablation of parahisian accessory pathways in pre-excitation syndrome is a challenging task, due to the extremely high risk of complete atrioventricular block. In this brief report we describe the case of a 32 year-old man presenting a parahisian accessory pathway, who has been successfully treated by radiofrequency ablation. Radiofrequency catheter ablation using low-power radiofrequency current is considered to be the most appropiate method of ablation in adult patients.

Korodi et al. (2016) conducted a case report in Pre-excitation syndrome with parahisian accessory pathway (n=1). Radiofrequency catheter ablation was evaluated on Successful ablation without complete AV block. Radiofrequency catheter ablation using low-power current successfully treated a parahisian accessory pathway in a 32-year-old man without causing complete atrioventricular block.
