Catheter ablation reduces all-cause mortality risk in AF-HF patients

Catheter ablation has been associated with a reduced risk of all-cause mortality compared with patients who did not undergo this procedure in a matched population-based atrial fibrillation (AF)-heart failure (HF) cohort. Regarding HF hospitalisations, stroke/ transient ischemic attack (TIA) and major bleeding, no difference in risk was detected between patients who underwent catheter ablation and those who did not. Nevertheless, researchers pointed out that larger studies are warranted to further assess this matter. Dr Michelle Samuel (McGill University Health Centre, Canada) and colleagues evaluated the long-term effectiveness of catheter ablation in patients with AF-HF in reducing the incidence of all-cause mortality, HF hospitalisations, and major morbidities (i.e. stroke/TIA and major bleeding) [1]. A population-based administrative cohort of 87,676 AF-HF patients was created for this purpose . Patients who underwent catheter ablation (n=298) were matc...
