Abstract

BACKGROUND

Permanent junctional reciprocating tachycardia (PJRT) is an infrequent form of atrioventricular re-entrant tachycardia. We report the clinical and electrophysiological properties of PJRT and outcomes of radiofrequency catheter ablation (RCA) in a large group of patients.

METHODS

We included 62 patients with the diagnosis of PJRT. Radiofrequency catheter ablation was performed in all.

RESULTS

Location of accessory pathway was right posteroseptal in 37 (59,7%) cases, right midseptal in 3 (4,8%), left posterior in 7 (11,3%), left lateral in 5 (8,1%), left posterolateral in 3 (4,8%), left anterolateral in 2 (3,2%), left posteroseptal in 2 (3,2%), middle cardiac vein in 2 (3,2%), and left coronary cusp in 1 (1,6%). Single procedure success rate was 90.3%. None of patients had recurrence during follow-up after repeat ablations. Overall long-term success rate was 98.4%. Left ventricular systolic function recovered in all patients with tachycardia-induced cardiomyopathy (TIC).

CONCLUSION

Retrograde decremental accessory pathways are mainly located in posteroseptal region. Radiofrequency catheter ablation is a safe and effective approach in patients with PJRT.

摘要

背景

永久性交接区折返性心动过速（PJRT）是一种少见的房室折返性心动过速形式。我们报告了一组大样本PJRT 患者的临床和电生理特征以及射频导管消融（RCA）的结果。

方法

我们纳入了 62 例 PJRT 患者。所有患者均行射频导管消融术。

结果

旁路的位置为右后间隔 37 例（59.7%），右中隔 3 例（4.8%），左后 7 例（11.3%），左外侧 5 例（8.1%），左后外侧 3 例（4.8%），左前外侧 2 例（3.2%），左后间隔 2 例（3.2%），心大静脉 2 例（3.2%），左冠状动脉瓣 1 例（1.6%）。单次手术成功率为 90.3%。重复消融后无患者复发。总长期成功率为 98.4%。所有心动过速性心肌病（TIC）患者的左心室收缩功能均恢复正常。
