Abstract

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.

摘要

少数室性早搏(PVC)和室性心动过速(VT)起源于心肌壁内,这对传统射频消融术构成了挑战。双极消融有潜力产生更深、更透壁的损伤,并且已被证明是这些病例的最佳治疗方法。双极消融的并发症风险相对较低,在消除或减轻室性心律失常负担方面有效。尽管双极消融有用且有效,但其临床应用有限,B-RF技术仍处于研究阶段且尚未广泛应用。本文综述了双极消融技术及其在特定情况下应用的所有优势。
