Abstract

Introduction
Left atrial appendage occlusion (LAAO) is recommended in patients with non-valvular atrial fibrillation (AF) who have contraindications to or are intolerant of long-term oral anticoagulants (OAC), but its impact on hospitalization rates has not been well described. The objective of our study is to describe the incidence of all-cause, bleeding-related, and thrombosis-related hospitalizations before and after LAAO.

Material and methods
We used the Nationwide Readmission Database to include patients aged ≥ 18 years with a diagnosis of AF who underwent transcatheter LAAO during the months of February-November in each year between 2016 and 2018. Patients who died during the index procedure or had missing length of hospital stay or mortality information were excluded.

Results
A total of 27,633 patients were included (median age: 77 years, 41% female) with an average pre- and post-LAAO monitoring period of 6.5 and 5.5 months respectively. Of these, 10,808 (39.1%) patients had one or more admissions prior to the procedure compared to 7,196 (26.0%) after the procedure. There was a 26% reduction in incidence of all-cause admissions (rate ratio (RR) = 0.74, 95% confidence interval (CI): 0.71–0.76; p < 0.001), 49% reduction in bleeding-related admissions (RR = 0.51, 95% CI: 0.48–0.55; p < 0.001), and 71% reduction in thrombosis-related readmissions (RR = 0.29, 95% CI: 0.26–0.33; p < 0.001) after LAAO.

Conclusions
In a contemporary, nationally representative dataset, we found that LAAO is associated with a significant decrease in all-cause, bleeding-related, and thrombosis-related admissions. These findings lend support to the current use of transcatheter LAAO in clinical practice for patients with contraindications to OAC and/or at high risk of bleeding.
