Key result
In-hospital mortality following transcatheter aortic valve replacement was similar between African American and Caucasian patients (3.3% vs 3.7%; P=0.99).
Why the study?
Are there racial disparities in the utilization and in-hospital outcomes of TAVR between African American and Caucasian patients with severe aortic stenosis?
Cohort (n=7,176)
Yes
Are there racial disparities in the utilization and in-hospital outcomes of TAVR between African American and Caucasian patients with severe aortic stenosis?
Absolute Event Rate: 3.3% vs 3.7%
p-value: p=0.99
There are no significant racial disparities in in-hospital mortality, complications, or cost between African American and Caucasian patients undergoing TAVR in contemporary US practice.
Supports equitable short-term TAVR outcomes by race; leaves open utilization patterns and longer-term disparities.
BACKGROUND: Racial disparities in cardiovascular care have been extensively investigated. The introduction of transcatheter aortic valve replacement (TAVR) revolutionized the treatment of aortic stenosis (AS) in the last decade. Whether a racial disparity in the utilization and outcome of TAVR exists is unknown. METHODS: We utilized the nationwide inpatient sample (NIS) to compare utilization rates, and in-hospital outcomes of Caucasians and African American (AA) patients who underwent TAVR between August 2011 and December 2014. RESULTS: A total of 7,176 patients (6870 Caucasians, 95.7%) and (306 AAs, 4.3%) were included in this analysis. Among patients who underwent aortic valve replacement between 2011 and 2014, the rates of TAVR utilization increased from 0.32% to 7.6% in AAs and from 0.4% to 8.8% in Caucasians. In propensity-matched cohorts of patients (n = 300 Caucasians and n = 300 AAs), in-hospital mortality was similar (3.7% and 3.3%, respectively, P = 0.99). Also, rates of key complications including stroke, permanent pacemaker implantation (PPMI), vascular complications, acute kidney injury, new dialysis, blood transfusion, and tamponade were similar in both races. There was also no significant difference between Caucasians and AAs with regards to length of stay, cost of hospitalization, and intermediate care facility utilization. CONCLUSIONS: There was no significant difference in the utilization rates, in-hospital outcomes, and cost of TAVR between Caucasians and AA patients in contemporary US practice. Further comparative studies of surgical and TAVR in AAs and other racial minorities are warranted.

Alqahtani et al. (2017) conducted a cohort in Severe aortic stenosis (n=7,176). African American race vs. Caucasian race was evaluated on In-hospital mortality (p=0.99). In-hospital mortality following transcatheter aortic valve replacement was similar between African American and Caucasian patients (3.3% vs 3.7%; P=0.99).
