Key result
Bipolar radiofrequency catheter ablation successfully treated ventricular tachycardia originating from the deep posterosuperior process of the left ventricular base after prior failed ablations.
Why the study?
Ablation of ischemic ventricular tachycardia originating from the posterosuperior process of the left ventricular base using conventional unipolar energy sources can be challenging or impossible.
Can bipolar radiofrequency catheter ablation using a right atrial return electrode successfully treat ventricular tachycardia originating from the posterosuperior process of the left ventricular base?

Can bipolar radiofrequency catheter ablation using a right atrial return electrode successfully treat ventricular tachycardia originating from the posterosuperior process of the left ventricular base?
Bipolar radiofrequency catheter ablation using a right atrial return electrode can be a safe and successful treatment for refractory ventricular tachycardia originating from the deep posterosuperior process of the left ventricular base.
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.
