Key result
Temperature-controlled bipolar radiofrequency ablation using a diamond-embedded-tip catheter was described as an approach for intramural ventricular tachycardia.
Why the study?
RF catheter ablation efficacy is limited for intramural VT, and devices specifically for bipolar ablation are not widely available and often require custom fabrication.
Case Report
Describes the first experience of using a diamond-embedded-tip catheter for temperature-controlled bipolar radiofrequency ablation of intramural ventricular tachycardia.
Supports feasibility of diamond-embedded-tip catheter for bipolar ablation in intramural VT; hypothesis-generating, prospective validation required.
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.
