Managing patients with atrial fibrillation often requires a dual approach focusing on rhythm control and stroke prevention. Traditionally, catheter ablation for rhythm management and percutaneous left atrial appendage occlusion (LAAO) for stroke risk reduction are performed as separate interventions. However, the strategy of concomitant AF ablation and LAAO in a single clinical session is gaining traction to improve procedural efficiency and reduce the cumulative risks associated with multiple access surgeries.
Recent evidence from a large-scale retrospective cohort study suggests that the combined approach does not compromise patient safety. After matching patients for various comorbidities and baseline characteristics, researchers found that the incidence of adverse events was remarkably similar between those receiving the combined treatment and those undergoing LAAO alone. Specifically, mortality rates remained low and balanced at both 90 days and the one-year follow-up mark.
Beyond early periprocedural safety, the study evaluated long-term outcomes such as stroke, device-related thrombus, and device leak. The data revealed no significant differences in these critical complications over 12 months. These findings support the use of concomitant AF ablation as a viable and safe strategy for appropriately selected patients, potentially streamlining the care pathway for complex cardiac cases.
Performing both procedures at once reduces the need for multiple hospital admissions and lessens the total number of invasive access sessions, which may lower the overall burden on the patient.
Clinical data indicates that the risk of stroke, device-related thrombus, and other complications at one year is comparable to performing LAAO as a standalone procedure.
