Hybrid Ablation in Atrial Fibrillation: Bridging Mechanistic Understanding and Clinical Practice

Year: 2025

Type: article

Abstract: Atrial fibrillation (AF), the most prevalent sustained cardiac arrhythmia, poses a significant burden on global morbidity and healthcare expenditure. Although endocardial catheter ablation and surgical ablation are established therapeutic strategies, each exhibits inherent limitations in achieving comprehensive substrate modification. Hybrid ablation therapy, integrating both endocardial and epicardial approaches, aims to overcome these limitations by enabling the more extensive and transmural targeting of arrhythmogenic foci and the complex atrial substrate. This review synthesizes the electrophysiological basis and mechanistic rationale underpinning hybrid AF ablation, highlighting its potential for an enhanced efficacy compared to isolated techniques. Furthermore, it introduces the emerging paradigm of three-dimensional ablation within this evolving field.
