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

In this exploratory, hypothesis-generating analysis of NVAF patients with low HAS-BLED scores undergoing combined CA and LAAO, renal insufficiency, history of MI, and advanced age were associated with bleeding events. These findings suggest that conventional risk scores may not fully capture bleeding risk in this setting but require validation in larger, prospective multicenter cohorts before clinical application.
