Risk Factors for Bleeding Following Combined Catheter Ablation and Left Atrial Appendage Occlusion in Patients With Nonvalvular Atrial Fibrillation and Low Baseline Bleeding Risk: An Exploratory Analysis
Abstract
BACKGROUND AND OBJECTIVE: In patients with nonvalvular atrial fibrillation (NVAF) undergoing combined catheter ablation (CA) and left atrial appendage occlusion (LAAO), bleeding events may occur even among those classified as low risk by the HAS-BLED score (≤2). This exploratory study aimed to identify factors associated with post-procedural bleeding in this specific population. METHODS: This single-center retrospective analysis included 209 NVAF patients with HAS-BLED ≤2 who underwent first-time CA and LAAO between 2021 and 2023. Patients with active bleeding or severe hepatic/renal impairment (estimated glomerular filtration rate (eGFR)
