Does tailored substrate-based focal pulsed field catheter ablation improve procedural success and freedom from arrhythmias in patients with atrial fibrillation and advanced atrial substrate?
Tailored substrate-based focal pulsed field ablation is feasible and effective, achieving 100% acute procedural success and 64% freedom from arrhythmias at 6 months in patients with AF and advanced atrial substrate.
Tailored substrate-based F-PFA in patients with AF and advanced atrial substrate is safe and effective. Acute procedural success was 100% with 64% freedom from arrhythmias after 6 months.
Farnir et al. (2025) studied this question.
