INTRODUCTION
Radiofrequency (RF) catheter ablation (RFCA) of ventricular tachycardia (VT) is an effective method of treatment. However, when arrhythmia has ischemic etiology and originates from the posterosuperior process (PSP) of the left ventricular (LV) base, ablation performed with conventional unipolar energy sources may be challenging or impossible.
METHOD AND RESULT
A 67-year-old male after six unsuccessful RFCA for highly symptomatic VT originating from PSP of LV base underwent successful RFCA using multiple bipolar RF applications delivered between two electrodes located at LV endocardium and adjacent right atrial sites.
CONCLUSION
This case report shows that bipolar RFCA can be used for safe and successful treatment of VT originating from deep PSP of LV base.
引言
室性心动过速（VT）的射频（RF）导管消融术（RFCA）是一种有效的治疗方法。然而，当心律失常具有缺血性病因且起源于左心室（LV）基底部的后上嵴（PSP）时，使用传统单极能量源进行消融可能具有挑战性或无法实现。
方法与结果
一名67岁男性，因起源于LV基底部PSP的高度症状性VT进行了6次RFCA均未成功，随后使用位于LV心内膜和相邻右心房部位的两个电极之间进行的多次双极RF应用，成功完成了RFCA。
结论
本病例报告表明，双极RFCA可用于安全、成功地治疗起源于LV基底部深部PSP的VT。
