Although long present, racial/ethnic disparities in cardiovascular care are increasingly recognized. A study of >32,000 patients with severe symptomatic aortic stenosis (AS) found that Black patients were less likely than White patients to undergo aortic valve replacement (AVR) (1). In their study utilizing a large clinical echocardiographic database, Patel et al. (2) found an overall prevalence of severe AS of 0.29% in Black patients and 0.91% in White patients (2). However, these and other studies are limited by selection bias and a lack of data/power for races/ethnicities other than Black and White. Understanding and addressing inequities in the treatment of AS requires an understanding of possible racial/ethnic differences in the prevalence of AS.
