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.

Connected Facts

Aortic Stenosis

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.

Prevalence & Incidence, Human Burden

Aortic Stenosis

Many cases of HVD are diagnosed during a routine physical check-up

Six in 10 patients did not have or recognize symptoms of heart valve disease (HVD) and were only diagnosed after going to their doctor for a regular check-up or a visit for something else.

Aortic Stenosis

HVD patients knew little prior to their diagnosis

More than 2/3 of valve disease patients knew a limited amount or nothing about heart valve disease (HVD) before their diagnosis.

Aortic Stenosis

Many Americans know nothing about HVD

Of those Americans surveyed ages 65+, 30% know nothing about heart valve disease (HVD).

Aortic Stenosis

American knowledge of HVD

A survey of Americans found that only 1 in 4 know “somewhat” or a “great deal” about heart valve disease (HVD). Forty percent know nothing about the disease.
