AF and heart failure with reduced ejection fraction (HFrEF) frequently coexist. Catheter ablation is an increasingly utilised treatment strategy for patients with AF and can be safely performed and is effective in achieving sinus rhythm for patients with HFrEF. Successful ablation may result in improved LV function, clinical heart failure status, quality of life and possibly even mortality. This review summarises the literature analysing efficacy, safety and outcomes of AF ablation for patients with HFrEF.

The degree to which clinical outcomes are worsened in patients with atrial fibrillation (AF) with heart failure (HF) compared with those without HF is not well described. This study aimed to determine the impact of HF on clinical outcomes in patients with AF. We analyzed data from Outcomes Registry for Better Informed Treatment of Atrial Fibrillation, a national registry of 10,135 patients with AF to determine associations between HF and left ventricular ejection fraction (LVEF) and outcomes, including stroke, mortality, and hospitalization using Cox multivariable modeling...

BACKGROUND: Atrial fibrillation (AF) is common in heart failure (HF), but the outcome by type of AF is largely unknown. OBJECTIVES: This study investigated outcomes related to type of AF (paroxysmal, persistent or permanent, or new onset) in 2 recent large trials in patients with HF with reduced ejection fraction. METHODS: The study analyzed patients in the PARADIGM-HF (Prospective comparison of ARNI with ACEI to Determine Impact on Global Mortality and morbidity in Heart Failure) and ATMOSPHERE (Aliskiren Trial to Minimize Outcomes in Patients with Heart Failure) trials...

Heart failure (HF) and atrial fibrillation (AF) are two conditions that are likely to dominate the next 50 years of cardiovascular (CV) care. Both are increasingly prevalent and associated with high morbidity, mortality, and healthcare cost. They are closely inter-related with similar risk factors and shared pathophysiology. Patients with concomitant HF and AF suffer from even worse symptoms and poorer prognosis, yet evidence-based evaluation and management of this group of patients is lacking. In this review, we evaluate the common mechanisms for the development of AF in HF patients and vice versa, focusing on the evidence for potential treatment strategies...

Heart failure (HF) and atrial fibrillation (AF) commonly coexist, adversely affect mortality, and impose a significant burden on healthcare resources. The presence of AF and HF portends a poor prognosis as well as an increased thromboembolic risk. In patients whose AF is symptomatic, rhythm restoration with either antiarrhythmic drugs or procedural therapies (e.g., pulmonary vein isolation, either catheter-based or surgical) should be considered for symptom improvement, though a mortality benefit has yet to be demonstrated...

BACKGROUND: Atrial fibrillation (AF) frequently coexists with heart failure (HF). AIM: To assess clinical characteristics and to identify predictors of one-year outcome of patients hospitalised for HF, depending on whether they were in sinus rhythm (SR) or had AF. METHODS: The study included Polish patients hospitalised for HF, participating in the Heart Failure Pilot Survey of the European Society of Cardiology, who were followed for 12 months after discharge...

BACKGROUND: Catheter ablation of atrial fibrillation (AFCA) is an established therapeutic option for rhythm control in symptomatic patients. Its efficacy and safety among patients with left ventricular systolic dysfunction is based on small populations, and data concerning long-term outcome are limited. We performed this meta-analysis to assess safety and long-term outcome of AFCA in patients with left ventricular systolic dysfunction, to evaluate predictors of recurrence and impact on left ventricular function...

Cardiomyopathy is a heterogeneous group of diseases of heart muscle accompanied with impaired cardiac function. Tachycardia-induced cardiomyopathy (TIC) is caused by prolonged tachycardia leading to dilatation and systolic dysfunction with clinical manifestation of heart failure. This state is reversible after normalization of heart rate. The diagnosis is usually made retrospectively after normalization of heart rate and recovery of left ventricular function (LVF). More than 100 years after the first documented case (described in 1913 in a young patient with atrial fibrillation and symptoms of heart failure [25]) is still limited knowledge of pathophysiological mechanisms...

BACKGROUND: Heart failure and atrial fibrillation (AF) often coexist in a deleterious cycle. OBJECTIVE: To evaluate the clinical and echocardiographic outcomes of patients with ventricular systolic dysfunction and AF treated with radiofrequency (RF) ablation. METHODS: Patients with ventricular systolic dysfunction [ejection fraction (EF) <50%] and AF refractory to drug therapy underwent stepwise RF ablation in the same session with pulmonary vein isolation, ablation of AF nests and of residual atrial tachycardia, named "background tachycardia"...

Patients with newly diagnosed cardiomyopathy require careful assessment of cause and initiation of treatment before the decision is made to implant an internal cardiac defibrillator. In patients with medicine-refractory atrial fibrillation and cardiomyopathy, atrioventricular node ablation and implantation of a biventricular pacemaker is the therapy of choice when tachycardia-induced cardiomyopathy is suspected and curative therapy is not possible.
