Comparison of Adverse Events between Isolated Left Atrial Appendage Closure and Combined Catheter Ablation

ABSTRACT: (1) Background: This study aimed to investigate the effect of an additional catheter ablation (CA) procedure on the risk of post-procedure adverse events during CA combined with left atrial appendage closure (LAAC). (2) Methods: From July 2017 to February 2022, data from 361 patients with atrial fibrillation who underwent LAAC at our center were analyzed retrospectively. The adverse events were compared between CA + LAAC and LAAC-only groups. (3) Results: The incidence of device-related thrombus (DRT) and embolic events was significantly lower in the CA + LAAC group than in the LAAC-only group (p = 0.01 and 0.04, respectively). A logistic regression analysis revealed that the combined procedure served as a protective factor for DRT (OR = 0.09; 95% confidence interval: 0.01–0.89; p = 0.04).
