ABSTRACT
Background:
Previous studies have shown that women with atrial fibrillation (AF) have a higher incidence of recurrence and non-pulmonary vein (non-PV) triggers. However, there remains an incomplete understanding of the impact of gender on AF ablation strategies and outcomes.Objective:
The purpose of this study was to evaluate the impact of gender on AF ablation outcomes.Methods:
We analyzed 1568 AF ablations in 1412 patients (34% female) performed at a single tertiary care center between January 2013 and July 2021. Patients were followed for at least 6 months (mean 34 months) for detection of AF recurrence, complications, and emergency department visits/hospitalizations. The effect was assessed by multivariate logistic regression analysis using propensity score matching (PSM).Results:
Mean age was 64 years, and mean body mass index (BMI) was 31 kg/m2. Seventy-seven percent of patients underwent de novo ablations. Twenty-seven percent of patients had persistent AF, with a recurrence rate of 37%. There was no difference in AF recurrence when stratified by gender (hazard ratio [HR] 1.15; 95% confidence interval [CI] 0.92-1.43; P >.05) and age. After PSM gender 11 (criteria age, type of AF, hypertension, diabetes mellitus, and BMI; n = 888 patients), there was no difference in AF recurrence or procedure-related complications. Having a history of persistent AF (HR 1.54; 95% CI 1.18-1.99; P = .001) predisposed to recurrence of AF. Persistent AF (HR 2.99; 95% CI 1.94-4.78; P <.001) and age >70 years (HR 1.03; 95% CI 1.02-1.05; P <.001) were associated with the need for additional substrate modification with no difference based on gender.Conclusion:
There was no difference in overall safety or efficacy outcomes between genders after AF ablation.
