Background: There are concerns that transcatheter or surgical aortic valve replacement (TAVR/SAVR) procedures are preferentially available to White patients. Methods: We stratified Medicare beneficiaries hospitalized with principal diagnosis of AS between 2012 and 2019 (n=299,976) by self-reported race/ethnicity (Black, Hispanic, Asian, Native American, and White). We evaluated AVR rates within 6 months of index hospitalization and associated procedural outcomes, including 30-day and 1-year mortality, and discharge disposition. We fitted Cox-proportional hazard models for outcomes, adjusting for demographics and comorbidities using race/ethnicity subgroup-specific-stabilized inverse probability weights. Results: Within 6 months of an index admission for AS, 86.8% (122,457 SAVR; 138,026 TAVR) patients underwent AVR. Overall, compared with White people, Black [HR 0.87 (0.85-0.89)], Hispanic [0.92 (0.88 - 0.96)], and Asian [0.95 (0.91 - 0.99)] people were less likely to receive AVR (Figure). Among patients who were admitted emergently/urgently, White patients (41.1%, 95% CI 40.7-41.4) had a significantly higher AVR rate within 6 months compared with Black (29.6%, 95% CI 28.3-30.9), Hispanic (36.6%, 95% CI 34.0-39.3), and Asian patients (35.4%, 95% CI 32.3-38.9). AVR rates increased annually for all race/ethnicities. There were no significant differences in 30-day or 1-year mortality by race. Black people were significantly more likely to be discharged to a facility compared with others. Conclusion: Within 6 months of AS admission, AVR rates are lower for Black, Hispanic, and Asian people compared with White people. These race-based differences in ultimate treatment of AS likely represent complex issues across the diagnosis and management of AS, warranting a comprehensive reassessment of the entire care spectrum for disadvantaged populations.
