Metabolic Dysfunction-Associated Steatotic Liver Disease and Atrial Fibrillation Recurrence After Catheter Ablation: A Systematic Review and Meta-Analysis

Background

Catheter ablation (CA) is an established rhythm-control strategy for atrial fibrillation (AF); however, AF recurrence remains common and is influenced by the underlying cardiometabolic substrate, including metabolic dysfunction-associated steatotic liver disease (MASLD). This study aimed to evaluate the association of MASLD and MASLD-related fibrosis risk with AF recurrence following CA.
