Objective. To compare the efficacy of catheter ablation and medical therapy in patients with heart failure and atrial fibrillation. Methods. We searched randomized controlled trials comparing catheter ablation versus medical therapy for heart failure and atrial fibrillation through PubMed, MEDLINE, Embase, Cochrane Clinical Trials Database, Web of Science, and China National Knowledge Infrastructure. Articles were investigated for their methodological quality using the Cochrane Collaboration risk of the bias assessment tool. Forest plots, funnel plots, and sensitivity analysis were also performed on the included articles. Results were expressed as risk ratio (RR) and mean difference (MD) with 95% confidence intervals. Results. Nine (9) studies were included in this study with 1131 patients. Meta-analysis showed a reduction in all-cause mortality from catheter ablation compared with medical therapy (RR = 0.53, 95% CI = 0.37 to 0.76; P = 0.0007 ) and improved left ventricular ejection fraction (LVEF) (MD = 6.45, 95% CI = 3.49 to 9.41; P < 0.0001 ), 6-minute walking time (6MWT) (MD = 28.32, 95% CI = 17.77 to 38.87; P < 0.0001 ), and Minnesota Living with Heart Failure Questionnaire (MLHFQ) score (MD = 8.19, 95% CI = 0.30 to 16.08; P = 0.04 ). Conclusion. Catheter ablation had a better improvement than medical treatment in left ventricular ejection fraction, cardiac function, and exercise ability for atrial fibrillation and heart failure patients.

Abstract Background Catheter ablation improves clinical outcomes in symptomatic atrial fibrillation (AF) patients with heart failure (HF) with reduced ejection fraction (HFrEF). However, the role of catheter ablation in HF patients with a preserved ejection fraction (HFpEF) is less clear. Purpose To determine the efficacy of catheter ablation of AF in patients with HFpEF relative to those with HFrEF. Methods We performed an extensive literature search and systematic review of studies that compared AF recurrence at one year after catheter ablation of AF in patients with HFpEF versus those with HFrEF. Risk ratio (RR) 95% confidence intervals were measured using the Mantel-Haenszel method for dichotomous variables, where a RR&lt;1.0 favors the HFpEF group. Results Four studies with a total of 563 patients were included, of which 312 had HFpEF and 251 had HFrEF. All patients included were undergoing first time catheter ablation of AF. Patients with HFpEF experienced similar recurrence of AF one year after ablation on or off antiarrhythmic drugs compared to those with HFrEF (RR 0.87; 95% CI 0.69–1.10, p=0.24), as shown in Figure 1. Recurrence of AF was assessed with electrocardiography, Holter monitoring, and/or event monitoring at scheduled follow-up visits and final follow-up. Conclusion Based on the results of this meta-analysis, catheter ablation of AF in patients with HFpEF appears as efficacious in maintaining sinus rhythm as in those with HFrEF.

Background Randomised data on patient-related outcomes comparing catheter ablation to medical therapy for the treatment of atrial fibrillation (AF) have shown the effectiveness of catheter ablation. Ablation versus medical therapy should also be analysed from a health economics perspective to achieve optimal healthcare resource allocation. Purpose To determine the cost effectiveness of catheter ablation compared to medical therapy for the treatment of atrial fibrillation, from the perspective of the UK National Health Service. Methods A patient-level Markov health-state transition model was used to conduct a cost utility analysis comparing catheter ablation and medical therapy for the treatment of AF. A systematic review and meta-analysis of catheter ablation treatment versus medical therapy (rhythm and/or rate control drugs) was conducted to enable comparison of AF recurrence between treatment groups utilising the model. Additional model parameters were established based upon a best-evidence review of the literature. The model simulated care delivered from a secondary care perspective. Total patients simulated in this model over a lifetime were 250,000, with patients entering the model at age 64. Only previously treated AF patients were included, including those with concomitant heart failure. A separate scenario analysis was conducted to determine the cost effectiveness specifically in the cohort of patients with AF and heart failure. Main outcomes measures Incremental cost-effectiveness ratio (ICER) and average total expected costs and quality-of-life years (QALYs) incurred over the lifetime of a patient. AF recurrence, complications and cardiovascular adverse events were compared over the total duration inside the model. Results In the base case analysis, catheter ablation resulted in a favourable ICER of £8,614 per additional QALY gained when compared to medical therapy, well below the national Willingness-to-Pay threshold of £20,000. Catheter ablation was associated with an expected increase of 1.01 QALYs, while adding an additional cost £8,742 over a patient’s lifetime. The cost-effectiveness of catheter ablation was improved in the heart failure sub-group analysis, with an ICER of £6,438. A significantly greater proportion of patients in the medical therapy group failed rhythm control at any stage compared to catheter ablation (72% vs 24%) and at a faster rate (median time to treatment failure: 3.8 vs 10 years). Conclusion Catheter ablation appears to be a highly cost-effective treatment for atrial fibrillation, compared to medical therapy, from the perspective of the UK National Health Service. With low rates of adverse events and superiority in achieving rhythm control, AF ablation services should be prioritised with appropriate allocation of healthcare resources.

The CABANA and CAPTAF trials report more data on the effects of catheter ablation vs. antiarrhythmic medication on quality of life for patients with atrial fibrillation than previously available systematic reviews. However, these publications do not report data for all-cause mortality and cardiac hospitalization in a form that can be integrated into recent meta-analyses. Recent meta-analysis estimates for the effect of catheter ablation on all-cause mortality suggest a reduction in patients with comorbid heart failure with reduced ejection fraction (HFrEF) (risk ratio [RR] 0.52, 95% CI 0.33 to 0.81, n=732, 5 trials) and an unclear effect in patients without comorbid HFrEF (RR 0.88, 95% CI 0.29 to 2.61, n=710, 4 trials). CABANA (n = 2,204) reported mortality for all patients combined (hazard ratio 0.86, 95% CI 0.65 to 1.15), and subgroup analyses by presence or absence of HFrEF would be useful to determine consistency with other trials and, if consistent, increase precision of pooled effect estimates. CAPTAF (n = 155) (which included almost exclusively patients without comorbid heart failure) did not report the mortality outcome data. Both trials collected data on cardiac hospitalization. A recent meta-analysis suggests a reduction in cardiac hospitalization in patients with comorbid HFrEF (RR 0.63, 95% CI 0.46 to 0.87, n=632, 3 trials) and in patients without comorbid HFrEF (RR 0.32, 95% CI 0.23 to 0.45, n=629, 4 trials). Again, however, the CABANA and CAPTAF trials did not report these data in a way that would allow them to be integrated into existing meta-analyses or did not report these data at all. Reporting key clinical outcomes from these trials with subgrouping by comorbid HFrEF could provide substantially more data than the prior body of evidence and inform best current estimates for this comparison.
