Atrial fibrillation ablation in heart failure

Abstract

Abstract Atrial fibrillation (AF) and heart failure (HF) commonly coexist in the same patient and either condition predisposes to the other. Several mechanisms promote the pathophysiological relationship between AF and HF, reducing quality of life, increasing the risk of stroke, and worsening HF progression. Although restoration and maintenance of sinus rhythm would be ideal for those patients, several trials comparing rhythm and rate control failed to show a benefit of rhythm control strategy, achieved with pharmacological therapy, in terms of hospitalization for HF or death. Catheter ablation is a well-established option for symptomatic AF patients, resistant to drug therapy, with normal cardiac function. Several recent studies have shown an improvement in clinical outcomes after AF ablation in HF patients highlighting the emerging role of the invasive approach in this subset of patients. However, several concerns regarding patients’ selection and standardization of the procedure still remain to be addressed.
