An unusual case of permanent junctional reciprocating tachycardia: Successful ablation at the mitral annulus-aorta junction

  • 168 Accesses

  • 8 Citations


A 25-year-old woman with drug-refractory permanent junctional reciprocating tachycardia (PJRT) and a previous failed ablation, was referred to our institution. Electrophysiological study confirmed the diagnosis of orthodromic atrioventricular reentry tachycardia using a slowly conducting accessory pathway. This accessory pathway was successfully ablated by conventional radiofrequency at the left anteroseptal region using a transseptal approach. Catheter ablation of this accessory pathway (Coumel type) at the mitral annulus-aorta junction offers insights on a rare anatomical location of PJRT.
