Abstract

Background: Atrial fibrillation (AFib) management in patients with active malignancy is challenging due to heightened thromboembolic and bleeding risks. Oral anticoagulation (OAC) remains standard, but left atrial appendage closure (LAAC) may provide a non-pharmacologic alternative. we wanted to compare clinical safety and efficacy outcomes of OAC versus LAAC in patients with active cancer and non-valvular AFib. Methods: A retrospective analysis of pooled data from multicenter observational cohorts including 1,432 patients (OAC: n = 932; LAAC: n = 500) with active cancer and AFib. Outcomes included stroke, major bleeding, and all-cause mortality at 12 months. Results: Stroke occurred in 2.3% of LAAC vs. 3.8% of OAC patients (p = 0.12). Major bleeding occurred in 4.4% of LAAC vs. 11.1% of OAC patients (p < 0.001). All-cause mortality was lower in LAAC patients (14.6% vs. 20.3%, p = 0.01). Conclusion: In cancer patients with AFib, LAAC demonstrated similar stroke prevention but significantly lower bleeding and mortality rates compared to OAC, suggesting it may be a safer long-term option for select high-risk patients.
