How does aortic stenosis
affect the aortic valve?
A patient with aortic stenosis will experience calcification, lipid deposition, and inflammatory
infiltration of the aortic valve leaflets. Over time, these leaflets become increasingly stiff, leading to a
narrowing of the heart valve opening, obstructing blood flow and forcing the heart to pump harder.2
How common is aortic stenosis?
In order to understand the prevalence of the disease,
please enter an estimate of the number of patients over 75 you see per week:
Elderly patients you see per year with aortic stenosis4
Patients who have moderate or severe aortic stenosis4
Patients who won’t survive past 2 years if left untreated5
It is likely that these numbers will only increase as
populations continue to age. How many patients
have you suspected of aortic stenosis?
Once symptoms appear in patients with severe AS, life expectancy
is severely reduced.3
Aortic stenosis can be latent in patients for a number of years, but once symptoms manifest life expectancy is significantly reduced.7
The murmur typically associated with aortic stenosis is a harsh systolic
ejection murmur, with a single or paradoxically split second heart sound.
Listen below to compare this to a normal heartbeat.

To support you in your practice a number of aortic stenosis educational materials have been developed, including materials to support patient consultation. All resources can be posted directly to your practice and are provided at no charge.
