Economic Burden

Aortic Stenosis

SAS patient hospitalization costs

Symptomatic aortic stenosis (SAS) patients who do not undergo treatment cost Medicare as much as $1.3 billion each year due to rehospitalization, prolonged stays, admissions to skilled nursing facilities, and use of hospice care.

Aortic valve disease (AVD) (symptomatic and asymptomatic) costs the U.S. $10.2 billion in direct costs each year.

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

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

Survival rates of sSAS patients who do not undergo valve replacement

Patients with severe symptomatic aortic stenosis (sSAS) who do not undergo valve replacement have survival rates as low as 50% at two years and 20% at 5 years after the onset of symptoms.

Human Burden

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
