Catheter Ablation for Hospitalized Atrial Fibrillation Patients with Reduced Systolic Function: Analysis of Inpatient Mortality, Resource Utilization and Complications.

Background: Randomized trials have shown improvement in hard clinical end points when catheter ablation (CA) is employed as a management strategy for certain atrial fibrillation (AF) patients with heart failure and reduced ejection fraction (HFrEF). Limited data, however, exist in this realm outside the controlled clinical trial settings. We sought to determine real-world data on mortality and complications after utilization of CA in such patients.
