First experience of temperature-controlled bipolar radiofrequency ablation of ventricular tachycardia originating from the anterior left ventricle using a diamond-embedded-tip catheter

Radiofrequency (RF) catheter ablation is an effective option for ventricular tachycardia (VT) in many patients, but its efficacy is limited when the origin of the VT is intramural. Bipolar ablation is an approach for patients who have failed conventional unipolar ablation. The efficacy and safety of bipolar ablation is gradually being recognized, although devices specifically for bipolar ablation are not widely available and often have to be custom made.
