Aortic Stenosis – What is it?

Aortic Stenosos

Aortic stenosis (AS) is a heart condition that occurs when the aortic valve (the valve between the left ventricle and aorta) narrows, partially obstructing blood flow across the valve. AS is often caused by calcification of the aortic valve as one ages, which stiffens the valve and narrows the valve opening.  Patients with AS may not experience any symptoms, as AS typically develops over many years. However, in patients with advanced AS, chest pain, dizziness and fainting during exercise, and congestive heart failure are common symptoms.
