Key result
Bipolar radiofrequency ablation creates deeper lesions to eliminate refractory intramural ventricular arrhythmias.
Why the study?
Ablation of intramural ventricular arrhythmias may require advanced techniques to achieve effective energy transfer, and bipolar catheter ablation can achieve deeper lesion formation for refractory arrhythmias.
Provides a step-by-step guide on performing bipolar radiofrequency ablation for intramural ventricular arrhythmias refractory to standard ablation.
Radiofrequency (RF) ablation of intramural ventricular arrhythmias (VAs) may require advanced ablation techniques to achieve effective energy transfer to the targeted tissue. As an alternative to standard RF ablation, catheter ablation can also be conducted in bipolar configuration when two ablation catheters participate in the RF circuit. This strategy has proved to result in deeper lesion formation and may be effective for eliminating arrhythmias that have been refractory to standard ablation. In this article, we provide a step-by-step guide on when and how to perform bipolar ablation of VAs.
