Catheter ablation is considered as the mainstay treatment for patients with symptomatic atrial fibrillation (AF). We aimed to determine the predictors of 30-day readmission after catheter ablation for AF.


The study cohort consisted of patients who underwent AF catheter ablation (International Classification of Diseases, Ninth Revision 427.31 and procedure code 37.34) in 2014, identified from the National Readmission Database.


Our final cohort consisted of 5322 unweighted cases, of which 4736 (89%) constituted the no-readmission group and 586 patients (11%) the readmission group. Female gender (OR 1.62, 95% CI 1.35–1.95), CAD (OR 1.36, 95% CI 1.08–1.71), peripheral vascular disease (OR 1.45, 95% CI 1.07–1.98), acute renal failure (OR 1.46, 95% CI 1.09–1.97), fluid and electrolyte disorders (OR 1.32, 95% CI 1.03–1.67), chronic pulmonary disease (OR 1.25, 95% CI 1.01–1.53), ablation on the day of admission (OR 0.74, 95% CI 0.61–0.91), and fourth quartile of hospital AF catheter ablation volume (OR 0.60, 95% CI 0.45–0.80) were independent predictors of 30-day readmission. Arrhythmias and heart failure were the most common cardiac etiologies for readmission. The most common ablation-related complications were hemorrhage (11%) and vascular (7%) complications.


Several patient- and hospital-related factors were identified as predictors of 30-day readmission, the knowledge of which can potentially improve healthcare delivery.
