Abstract
BACKGROUND: Increasing utilization of Pulsed Field Ablation (PFA) to treat atrial fibrillation (AF) has led to concerns related to tissue contact, hemolysis, and electroanatomic mapping integration. A novel balloon-in-basket PFA catheter offers form and function to address these concerns. OBJECTIVE: The VOLT-AF IDE study is a prospective, single-arm global IDE study designed to demonstrate the Volt PFA System is safe and effective for the treatment of paroxysmal (PAF) and persistent AF (PersAF). METHODS: Symptomatic, drug-refractory PAF and PersAF subjects were enrolled for de novo ablation. Ablation strategy was pulmonary vein isolation-only using the Volt PFA catheter with EnSite X EP System integration for visualization and dynamic contact display. Endpoints were the rate of device- or procedure-related SAE within 7 days and acute procedural success. RESULTS: A total of 392 subjects (57 roll-in, 335 primary analysis, 51.8% PAF, 64.7% male, age 65.0±11.0 years) were enrolled at 38 sites from April to September 2024. Acute isolation was observed in 99.4% of veins (666/670) in 98.2% of PAF subjects (162/165), and in 99.8% of veins (633/634) in 99.4% of PersAF subjects (154/155), with 18.5±3.6 applications/patient. Primary safety endpoint events occurred in 1.9% of subjects. Procedural efficiency and acute outcomes did not differ with fluoroscopy use. Conscious or deep sedation was associated with increased procedural efficiency, with no difference in acute success compared to general anesthesia. No clinically relevant hemolysis or kidney injury was reported. CONCLUSION: These results demonstrate the acute safety and effectiveness of a novel balloon-in-basket PFA catheter to treat paroxysmal and persistent AF. Long-term outcome follow-up is ongoing.
