Abstract
BackgroundResearch has shown mixed results when comparing in-hospital complications following atrial fibrillation ablation in women compared to men. ObjectivesTo better quantify sex differences and in-hospital outcomes in atrial fibrillation ablation procedures and identify factors associated with poorer outcomes. MethodsWe queried the NIS database from 2016 to 2019 for hospitalizations with a primary diagnosis of atrial fibrillation ablation and excluded patients with any other arrhythmias, ICD/pacemaker placement. We assessed demographics, in-hospital mortality, and complications of women compared to men. ResultsAdmissions for atrial fibrillation were more common in females than males (849 050 vs. 815 665; p < .001). However, females were less likely to receive ablation (1.65% vs. 2.71%, OR: 0.60; 95% confidence interval: 0.57-0.64, p < .001), which persisted after adjusting for cardiomyopathy (adjusted OR: 0.61; 95% confidence interval: 0.58-0.65, p < .001). The primary outcome of in-hospital mortality was not statistically different in univariate analysis (0.39% vs. 0.36%, OR: 1.09, 95% CI: 0.44-2.72, p = .84), finding that did not change when adjusted for comorbidities (adjusted OR: 0.94, 95% CI: 0.36-2.49). The complication rate in hospitalized patients following ablation was 8.08%. The total unadjusted complication rate was higher for females than males (9.58% vs. 7.09%, p = .001); however, it was not significant when adjusted for risks (adjusted OR: 1.23, 95% CI: 0.99-1.53, p = .06). ConclusionFemale sex is not associated with increased complications or death in a real-world study of catheter ablation when results are adjusted for risks. However, females admitted with atrial fibrillation receive ablation less often than males during hospital admission.
