Aortic Stenosis  /  Cost of Disease

Aortic stenosis is one of the most common and serious types of heart valve disease. Aortic stenosis can be debilitating, costly, and deadly. Survival rates without treatment for severe symptomatic aortic stenosis are low at 50% at 2 years after symptom onset, and 20% at 5 years. Fortunately, innovative treatments are saving lives and aortic stenosis can be successfully treated with valve replacement in patients of all ages.
