Connected Facts

Aortic Stenosis

2016 prevalence of aortic valve disease in America

In 2016, as many as 5.8 million U.S. adults had aortic valve disease (AVD).

estimates by Bach et al. 2007

Prevalence & Incidence

Aortic Stenosis

All-cause mortality for aortic valve disorders

In 2014, all-cause mortality for aortic valve disorders was 34,408 in the U.S.

Human Burden

Aortic Stenosis

1 and 6-month mortality rates without treatment for sSAS

Waiting for treatment for severe symptomatic aortic stenosis (sSAS) can be deadly, with 1-month mortality at 3.7% and 6-month mortality at 11.6% (measured from the time intervention was recommended).

Human Burden

Aortic Stenosis

Lifespan of Medicare patients with sSAS who do not undergo treatment

Medicare patients with severe symptomatic aortic stenosis (sSAS) who do not undergo treatment have an average lifespan of 1.8 years.

Human Burden

Aortic Stenosis

Prevalence of AS in Americans 75+

An estimated 12.4%, or ~2.5 million people ages 75+ in North America, have AS.

Age - A Major Risk Factor

Aortic Stenosis

Aortic stenosis impacts majority of heart valve disease patients

Aortic stenosis (AS) is among the most common forms of heart valve disease (HVD), affecting 2% to 3% of the adult U.S. population.
