Aortic Stenosis
can‘t wait

An urgent evaluation is everything.

SSAS Patients

Approximately 25,000 Canadians are diagnosed annually with symptomatic severe aortic stenosis (SSAS).1-9


isn’t enough 

After developing symptomatic severe aortic stenosis, the average patient survival is two years without treatment. 12 


aortic stenosis
can be fatal

Aortic stenosis is among the most common of all valvular heart diseases and continues to increase as our population ages.13  Symptomatic severe aortic stenosis (SSAS) can be fatal if left untreated.

Early diagnosis and treatment
can mean better outcomes


  • Heart murmurs go undetected.14
  • Referrals are delayed or too late.14
  • Echocardiogram findings are misclassified due to complex cardiac anatomy.14
  • Patients don't recognize or report their symptoms.15
  • Patients refuse treatment.16

Aortic valve
greatly improves
the rate of survival 

Urgency is everything
for symptomatic
aortic stenosis patients

You can help save more lives by
recognizing the symptoms of SSAS early on.



For SSAS patients who are 65 to 80 years of age and have no anatomic contraindication to transfemoral TAVI, either SAVR or transfemoral TAVI is recommended after shared decision-making about the balance between expected patient longevity and valve durability.19


ESC/EACTS Valvular Heart Disease Guidelines: Class 1B recommendation: Patient with symptomatic severe high-gradient aortic stenosis should be treated. The treatment choice should be made by the Heart Team according to the individual patient characteristics.11


The patient perspective was incorporated in a recent report from Heart Valve Voice Canada, Heart Valve Disease: Working together to create a better patient journey provides a comprehensive view of the entire heart valve disease patient journey from first detection to diagnosis, follow-up, and treatment. The report describes what an optimal care pathway should be for people living with heart valve disease and provides a series of recommendation to improve the journey for these people.

It's easier to help patients when you know what they're thinking. The insights gathered from a new national survey conducted by, with support from Medtronic, can help you better understand the heart valve patient experience.

Share this resource with your patients: can help them learn more about their condition and find a supportive community of other patients diagnosed with SSAS.
