(Stenosis, Aortic—Adult; AS—Adult)
A birth defect of the aortic valve, which normally has three cusps:
- A two-part aortic valve becomes stenotic with progressive wear and tear
- An aortic valve that has only one cusp or has stenosis from birth
- Progressive hardening and calcification of the aortic valve with age
- Scarring of the aortic valve caused by rheumatic fever —rare
- Gender: male
- Family members with heart disease that affects the valves
- History of rheumatic fever
- Diabetes mellitus
- Extreme fatigue after exercise or exertion
- Fainting with exercise or exertion
- Pain, squeezing, pressure, or tightness of the chest usually occurring with exertion
- Rapid or irregular heartbeat
- Shortness of breath
- Lightheadedness with exertion
- Neurological symptoms of a stroke or transient ischemic attack
- Abnormal chest sounds such as a heart murmur or clicking sound
- Noticeable chest heave or vibration when the doctor's hand is held over your heart
- Balloon valvuloplasty —A balloon device is passed through the arteries to open or enlarge the stenotic aortic valve. This may provide temporary relief of symptoms. But since the valve can become blocked again, this treatment is not a permanent solution.
- Aortic valve replacement —During this open surgery, the defective heart valve is replaced with either a bioprosthetic valve or a synthetic valve.
- Transcatheter aortic valve replacement—This surgery also involves replacing the defective valve. But this is minimally invasive surgery that involves inserting the replacement valve through a small incision in the chest or through an artery in the leg.

- Get regular medical care, including exams and tests.
- Only certain people with AS need antibiotics before dental or medical procedures. Ask your doctor if you need antibiotics to prevent infection of the heart valve.
