Abstract:
Permanent form of junctional reciprocating tachycardia (PJRT) is an uncommon form of atrioventricular re-entrant tachycardia due to an accessory pathway characterized by slow and decremental retrograde conduction. The majority of accessory pathways in PJRT are localized in the posteroseptal zone. Despite the high success rate, failure may occur during endocardial radiofrequency catheter ablation due to epicardial insertion of the accessory pathway. We report a case of PJRT in a 25-year-old man in whom the accessory pathway was located epicardially in the posteroinferior region and ablated from within the middle cardiac vein by radiofrequency catheter ablation.
