Key result
AI-guided ablation linked to improved arrhythmia freedom vs conventional PVI in HF with persistent AF.
Why the study?
Catheter ablation is a cornerstone therapy for AF and HF, but the optimal ablation strategy remains debated, especially in patients with advanced HF symptoms.
Does an artificial intelligence-guided personalized ablation strategy improve freedom from atrial arrhythmia in patients with persistent AF and heart failure compared to conventional pulmonary vein isolation?
Does an artificial intelligence-guided personalized ablation strategy improve freedom from atrial arrhythmia in patients with persistent AF and heart failure compared to conventional pulmonary vein isolation?
An AI-guided personalized ablation strategy targeting spatiotemporal dispersion may improve rhythm control outcomes in patients with coexisting persistent AF and heart failure.
May support AI-guided ablation for better rhythm control in HF with persistent AF; leaves open need for randomized confirmation before practice change.
Atrial fibrillation (AF) and heart failure (HF) frequently coexist, creating a complex clinical scenario that amplifies morbidity and worsens prognosis. Catheter ablation emerged as a cornerstone therapy for rhythm control in this population, particularly in patients with reduced ejection fraction1. However, the optimal ablation strategy remains debated, especially in those with advanced HF symptoms. This research letter presents a sub-analysis of the TAILORED-AF trial, which investigated the efficacy of a personalized, dispersion-guided ablation strategy targeting regions of spatiotemporal dispersion (tailored arm) compared to conventional anatomical pulmonary vein isolation (PVI, anatomical arm) in patients with persistent AF2.
