Impact of Chronic Kidney Disease on the Outcomes of Patients Undergoing Left Atrial Appendage Occlusion: Insights from a Large National Database.

Introduction: Studies exploring the effectiveness and safety of left atrial appendage occlusion (LAAO) in patients with chronic kidney disease (CKD) are limited.

Methods: We utilized the National Inpatient Sample (NIS) to identify hospitalizations for LAAO from 2016 to 2020 and further identified cases with concomitant CKD. The primary outcome was mortality, and secondary outcomes were cerebrovascular accidents, major bleeding, vasopressor requirements, percutaneous coronary intervention, cardiac arrest, acute respiratory failure, transfusion, length of stay (LOS), and total hospital charges.
