- W3109303428 abstract "Abstract Background Atrial fibrillation (AF) is the most commonly encountered arrhythmia in clinical practice, even more so among patients with heart failure (HF). Results of the recent CABANA and CASTLE-AF trials indicate significant improvements in ejection fraction, HF readmissions as well as overall mortality with the incorporation of rhythm control strategies in HF patients. These findings challenge existing notions of equivalency of rate vs rhythm control strategies. In this study, we analyzed the impact of this evidence on treatment practices and the short term outcomes of ablation in this patient cohort. Methods We conducted a retrospective study using the AHRQ-HCUP National Readmission Database for the years 2005–2014. ICD 9 diagnosis codes were used to identify all adult patients (≥18 years) undergoing AF ablation procedures as well as a sub-cohort of patients with existing HF. Trends in the use of ablation procedures, patient characteristics as well as details of short term procedural outcomes were studied. Multivariate regression analysis was utilized to adjust for confounders. Complications were defined as per the Agency for healthcare research and quality guidelines. Independent risk factors for in-hospital mortality were identified using proportional hazards model. Results Our results indicate a trend of rising rates of AF ablation procedures overall with a peak in 2011 at 20,046 and gradual downtrend thereafter (10,195 in 2005 to 11735 in 2014). Our data revealed a consistent rise in ablation procedures among heart failure patients during the same period (832 to 2245). A definite reduction in peri-procedural mortality is noted (0.24% in 2005 to 0.17% in 2014, p=0.2) – an improvement that is maximally apparent in the heart failure group (2.49% to 0.4%, p=0.07). Overall complication rates however are significantly increased overall with a proportional rise noted among HF patients. Conclusions Our data from a nationally representative registry indicates an increasing utilization of ablation as a therapeutic modality in the management of atrial fibrillation in HF. Future prospective studies are required to assess the positive impact of these changes in clinical practice as offset by their associated complications. 10 year AF ablation trends in HF Funding Acknowledgement Type of funding source: None" @default.
