Middle kardiyak venden ablate edilen permanent junctional resiprokan taşikardi olgusu

Permanent junetional resiprokan taşikardi (PJRT), atrioventriküler reentran taşikardilerin oldukça nadir görülen bir formu olup, dekremental retrograd ileti özelliği gösteren aksesuar yola bağlı olarak gelişmektedir. PJRT'de aksesuar yolların büyük çoğunluğu tipik olarak posteroseptal yerleşim göstermekle birlikte diğer lokalizasyonlar da mümkündür. Endokardiyal radyofrekans kateter ablasyon işleminin yüksek başarı oranına sahip olmasına karşın, epikardiyal yerleşim gösteren aksesuar yollarda bu yaklaşım başarısız kalabilir. Bu yazıda, radofrekans kateter ablasyon işleminin başarılı bir şekilde "middle kardiak venden" yapıldığı epikardiyal yerleşim gösteren aksesuar yola sahip PJRT olgusu sunulmaktadır.

A case of permanent junctional reciprocating tachycardia ablated from within the middle cardiac vein

Permanent form of junetional 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 localized in the posteroseptal zone. Despite the high success rate, failure may occur during endocardial radiofrequeney catheter ablation due to epieardial insertion of the accessory pathway. We report a case of PJRT in a 25-year-old male in whom the accessory pathway was located epicardially in the posteroinferior region and ablated from within the middle cardiac vein by radiofrequeney catheter ablation.
