Catheter Ablation of Atrial Fibrillation in Patients With Heart Failure—Therapy or Futility?

Atrial fibrillation (AF) and heart failure (HF) frequently coexist, creating a bidirectional relationship in which each condition exacerbates the other, worsening patient prognosis. This interplay also presents therapeutic challenges, as traditional pharmacological strategies for rate and rhythm control are often limited in HF. Catheter ablation (CA) is an established treatment for maintaining sinus rhythm and providing symptomatic relief in patients with AF; however, its effect on clinical outcomes and prognosis in HF populations remains under investigation. This article offers a comprehensive overview of the management of AF and HF, with a focus on the evidence surrounding CA in this population. By analysing recent randomized controlled trials (RCTs) and guideline recommendations, this review aims to provide insights into the role of CA in managing AF and HF.
