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).

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
