Symptoms of aortic stenosis include shortness of breath, leg swelling, chest pain, and syncope- or passing out, fainting. An echocardiogram or ultrasound of the heart confirms the diagnosis. Surgery is the traditional treatment for severe aortic stenosis, but valves done through catheters are being tested.
