Impairment of quality of life (QoL) is a well-known complication of AF. Because of the association of AF with older age and many other cardiovascular comorbidities, there are multiple factors that could influence QoL score even after successful AF intervention. However, substantial improvement in QoL has been reported following catheter ablation for AF regardless of ablation outcomes. In terms of healthcare resource utilisation, the expenses associated with AF are very high because of the hospitalisations for AF-related thromboembolic complications, aggravation of heart failure, AF interventions, and emergency room visits for incessant arrhythmia episodes, and they represent a large economic burden worldwide. Several trials have shown a drastic reduction in healthcare costs following successful AF ablation. In this review, the authors discuss this evidence systematically.
