Background: Left atrial appendage occlusion (LAAO) is increasingly used as an alternative to oral anticoagulation for stroke prevention in select patients with atrial fibrillation. Data on outcomes in racial and ethnic minority individuals are limited. This analysis assessed differences in the utilization and outcomes of LAAO by race and ethnicity in a large national registry. Methods: This analysis acquired data on WATCHMAN FLX patients from the National Cardiovascular Data Registry (NCDR) LAAO Registry through September 2022. All patients with an attempted WATCHMAN FLX implantation and known race and ethnicity were included. Baseline characteristics and 1 year event rates were compared. Results: A total of 97,185 patients were analyzed; 87,339 were White (90%), 3,750 Black (Black/African American 3.9%), and 2,866 Hispanic ([Hispanic/Latinx] 2.9%). Black and Hispanic patients were younger with a higher incidence of prior stroke and significant bleeding compared to White patients. Black and Hispanic patients were treated with LAAO in smaller numbers relative to their proportion of the US population. Rates of procedural success were similar between groups. Though direct oral anticoagulants were prescribed in most patients across the groups, dual and single antiplatelet therapy were prescribed more often in Black patients. Black patients had significantly higher rates of 1-year death and bleeding compared to White and Hispanic patients. Conclusions: Patients from racial and ethnic minority groups comprise a disproportionately small fraction of all patients who undergo LAAO. Black and Hispanic patients were younger but had significantly higher comorbidities compared to White patients. Procedural success was similar amongst the groups but Black patients experienced higher rates of death and bleeding at 1 year.
