What is aortic stenosis?
Aortic valve stenosis (AS) is a disease of the aortic valve in which the opening of the valve is narrowed (stenotic).
This typically results from calcium that is deposited in the valve as people age. The calcium causes narrowing of the valve and prevents it from opening normally.
The normal size of the aortic valve is the size of a half dollar; a severely stenotic valve may be the size of a dime or smaller.
What are the symptoms of
Narrowing of the aortic valve increases the effort required by the heart to adequately pump blood to the body. Over time heart function will deteriorate, and the patient will develop symptoms. Symptoms include:
If untreated, 50% of patients with severe aortic stenosis die 2 years after symptoms are detected.
Who is a candidate for TAVR?
Traditional surgical aortic valve replacement (SAVR) continues to be associated with excellent outcomes and remains the gold standard for treatment of severe aortic stenosis. However, at Barnabas Heart, catheter-based procedures are available for patients who are high-risk for traditional surgical valve replacement.
