Key result
Simplified bipolar radiofrequency ablation eliminates refractory septal ventricular tachycardia with no recurrences at 6 months.
Why the study?
Bipolar ablation is necessary for targeting deep intramural arrhythmia sources but has been limited by restricted access to investigational or custom-made equipment.
Case Report (n=1)
No
May support simplified bipolar ablation for refractory septal VT; hypothesis-generating and requires prospective validation before practice change.
Key Teaching Points•Bipolar ablation is sometimes necessary for targeting deep intramural arrhythmia sources, but its availability to date has been limited by restricted access to investigational equipment or custom-made equipment.•Bipolar ablation can be safely and effectively performed without use of custom-made, modified, or investigational equipment, and with a widely available electroanatomic mapping system.•In this case, bipolar ablation utilizing a simplified configuration was able to be performed to effectively control refractory ventricular tachycardia originating from the interventricular septum. •Bipolar ablation is sometimes necessary for targeting deep intramural arrhythmia sources, but its availability to date has been limited by restricted access to investigational equipment or custom-made equipment.•Bipolar ablation can be safely and effectively performed without use of custom-made, modified, or investigational equipment, and with a widely available electroanatomic mapping system.•In this case, bipolar ablation utilizing a simplified configuration was able to be performed to effectively control refractory ventricular tachycardia originating from the interventricular septum.

Sauer et al. (2018) conducted a case report in Refractory ventricular tachycardia (n=1). Bipolar radiofrequency (Bi-RF) ablation using unmodified equipment was evaluated on Ventricular tachycardia noninducibility and lack of recurrence. Bipolar radiofrequency ablation using a simplified setup with unmodified equipment effectively controlled refractory ventricular tachycardia originating from the interventricular septum, with no recurrences at 6 months.
