Abstrakt: Septal ventricular tachycardias exhibit high recurrence rates after radiofrequency ablation, which is mainly attributed to the deep intramyocardial circuits and the inability to create transmural lesions with the conventional unipolar ablation. Bipolar radiofrequency ablation is feasible and it has been reported as a valid technique in these cases, leading to deeper lesion formation, high non-inducibility rates, and acceptable recurrence rates during follow-up. Our goal is to report a successful case of bipolar ablation of a septal ventricular tachycardia using a simple bipolar ablation configuration with two 8-mm tip catheters.
