Aortic Stenosis: Understanding Causes, Symptoms & Treatment

Aortic stenosis (AS) is a condition in which the aortic valve, which controls blood flow from the heart to the aorta (the main artery of the body), becomes narrowed. This narrowing can obstruct blood flow and make it difficult for the heart to pump blood effectively.

Aortic stenosis can be caused by a variety of factors, including:

- Congenital heart defects (present at birth)

- Degenerative changes related to aging

- Rheumatic fever (a bacterial infection)

- Radiation therapy

- Certain medications

Symptoms of aortic stenosis may include:

- Chest pain (angina)

- Shortness of breath

- Lightheadedness or dizziness

- Fatigue

- Fainting (syncope)

Treatment for aortic stenosis may include:

- Medications to relieve symptoms and slow the progression of the condition

- Balloon valvuloplasty, a procedure to widen the aortic valve

- Surgical aortic valve replacement

Aortic stenosis is a serious condition, but it can be successfully managed with treatment.
