First-in-Human Real-Time MR-Guided Ventricular Ablation for Idiopathic Outflow Tract Premature Ventricular Complexes

Can real-time magnetic resonance (MR)–guided radiofrequency ablation be safely and effectively performed for ventricular arrhythmias without fluoroscopy?In this first-in-human case from the VISABL-VT trial, a 73-year-old man underwent successful MR-guided ablation for symptomatic premature ventricular complexes using an MR-compatible electrophysiology platform, with complete ectopy suppression and no complications during or after the procedure.This case demonstrates the technical feasibility and safety of entirely real-time MR-guided ventricular ablation, supporting further clinical investigation.
