Management of Atrial Tachyarrhythmias in Heart Failure —an Interventionalist’s Point of View

AbstractPurpose of ReviewAtrial fibrillation (AF) and heart failure (HF) are commonly encountered clinical disorders that often co-exist, accelerating disease progression and adverse outcomes. It is known that restoration of sinus rhythm positively impacts this population; however, the complex comorbidity profile associated with HF introduces intricacies not encountered in other patient populations. The current review focuses on the safety and efficacy of an interventional-based management for atrial tachyarrhythmias in HF.Recent FindingsWhile pharmacotherapy has been the standard treatment of cardiac dysrhythmias in the HF population, recent evidence suggests catheter ablation is more effective and causes less harm than antiarrhythmic drugs (AADs) in the HF population.SummaryFor the maintenance of sinus rhythm, catheter ablation results in improved freedom from recurrent arrhythmia, with secondary benefit on mortality and hospitalization in those with HF and reduced ejection fraction. For those with permanent AF, cardiac resynchronization therapy and atrioventricular junction ablation result in improved quality of life, physical functioning, and cardiac function.
