The Lead Episode 85: Bipolar Radiofrequency Ablation of Refractory Ventricular Arrhythmias, Results from a Multi-Centre Network-The Lead Episode 85 (Video)

Video Transcription

Video Summary

In this episode of The Lead, recorded in Sydney at the APHRS, hosts Mike Lloyd, Wendy Zou, and Jason Jacobson discuss the innovative approach of bipolar radiofrequency ablation for treating refractory ventricular arrhythmias. They explore an article on this technique by Pyotr Futima, detailing a multi-center study conducted across 16 European centers. Bipolar ablation is differentiated from the traditional unipolar method by using two electrodes in proximity to enhance lesion depth, addressing challenges in treating deep myocardial sources. The study, involving 91 patients mostly refractive to previous ablations, demonstrated a 74% acute success rate. Although promising, the technique—considered a bailout strategy for complex cases—requires further long-term safety data, with complications like LAD occlusion noted. The discussion underscores the technique's potential impact, particularly in regions with limited access to advanced equipment, while remaining cautious about widespread initial use.
