A minority of premature ventricular contractions (PVC) and ventricular tachycardias (VT) have an intramural origin, which represents a challenge for conventional radiofrequency ablation. Bipolar ablation has the potential ability to create deeper and more transmural lesions and has been demonstrated to be optimal treatment in these cases. Bipolar ablation carries a relatively low risk of complications and is effective in eliminating or reducing the burden of ventricular arrhythmias. Despite its utility and efficacy, the clinical use of bipolar ablation is limited, and B-RF technology is still investigational and not widely available. This article reviews the technique of bipolar ablation and all its advantages when applied to specific scenarios.
