Key result
Bipolar RF ablation may improve efficacy and transmural lesion creation in refractory LV summit arrhythmias.
Why the study?
Challenging anatomy of the left ventricular summit and surrounding sites may prevent sufficient heating during standard radiofrequency catheter ablation, necessitating alternative approaches.
Does bipolar radiofrequency catheter ablation improve efficacy in patients with left ventricular summit arrhythmias refractory to standard approaches?
Does bipolar radiofrequency catheter ablation improve efficacy in patients with left ventricular summit arrhythmias refractory to standard approaches?
Bipolar radiofrequency catheter ablation offers a promising approach for treating left ventricular summit arrhythmias that are refractory to standard ablation techniques by increasing the likelihood of achieving transmural lesions.
Supports consideration in refractory LV summit arrhythmias; leaves open confirmation by randomized trials.
Challenging anatomic and morphologic conditions of the left ventricular (LV) summit architecture and its surrounding sites may prevent sufficient heating of the targeted area during standard radiofrequency catheter ablation. Bipolar ablation can result in higher likelihood of efficacy for ablation of LV summit arrhythmias from inaccessible regions and increase the chance of achieving a transmural lesion. In this review, the authors describe the present approaches for bipolar ablation of the LV summit arrhythmias refractory to standard approaches.
