Comparison of Fluoroscopy-only vs. Electroanatomic Mapping Strategies for Pulmonary Vein Isolation With Balloon-based Pulsed-field Ablation
Trial Parameters
Brief Summary
We designed a study to evaluate the impact of a two systematic strategies for PVI with the octaspline, balloon-based PFA (B-PFA) catheter. We hypothesized that the addition of electroanatomic guidance is non-superior to fluoroscopy-only guidance in achieving durable PVI.
