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

Increased hospital admissions and prolonged length of stay for patients who do not undergo treatment

Medicare severe symptomatic aortic stenosis (sSAS) patients who do not undergo treatment have an average of 1.9 hospital admissions per year and prolonged lengths of stay — 11.5 hospital days per patient-year.

Human Burden

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

Low detection rates for AS

Prevalence estimates for AS are likely low. A U.K. population screening found previously undetected HVD in 1 in 2 adults ages 65+.

Prevalence & Incidence

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.

  • Detection rate of heart murmurs
    More than 40% of heart murmurs — detected with a stethoscope and sometimes the first sign of heart valve disease (HVD) — are missed by family practitioners.  
  • Undertreatment of patients with sSAS
    AS is often undertreated — one study found that 56% of severe symptomatic aortic stenosis (sSAS) patients referred to a cardiothoracic surgeon were not operated on.
