Radiofrequency catheter ablation successfully treats PJRT with an atypical left lateral accessory pathway.
Case Report (n=1)
This case report highlights the rare occurrence of an atypically located accessory pathway in the left lateral region in a patient with PJRT, successfully treated with radiofrequency catheter ablation.
Supports ablation feasibility for rare atypical left lateral pathways in PJRT; leaves open generalizability pending larger series.
Permanent junctional reciprocating tachycardia (PJRT) is an uncommon form of atrioventricular reentrant tachycardia due to an accessory pathway characterized by slow and decremental retrograde conduction. The majority of accessory pathways in PJRT are located in the posteroseptal zone. Few cases of atypical location have been described. We report a case of PJRT in a 72-year-old woman in whom the accessory pathway was located in the left lateral region and treated by radiofrequency catheter ablation. A forma permanente de taquicardia juncional reciprocante é uma modalidade incomum de taquicardia auriculoventricular reentrante devida a via de acesso caracterizada por condução retrógada lenta e gradual. A maioria das vias acessórias na forma permanente da taquicardia juncional reciprocante está localizada na zona posterosseptal. Foram apresentados poucos casos de localização atípica1-4. Apresentamos o caso de forma permanente da taquicardia junctional reciprocante numa mulher de 72 anos na qual a via acessória foi colocada na região lateral esquerda sendo a ablação efetuada por cateter de radiofrequência.

Rodríguez‐Mañero et al. (2015) conducted a case report in Permanent junctional reciprocating tachycardia (PJRT) (n=1). Radiofrequency catheter ablation was evaluated. Radiofrequency catheter ablation successfully treated a 72-year-old woman with permanent junctional reciprocating tachycardia and an atypically located accessory pathway in the left lateral region.
