Answers to Common Aortic Stenosis Questions

Premier Health providers answer frequently asked questions about aortic stenosis.

What is aortic stenosis?

The American Heart Association (AHA) defines aortic stenosis (AS) as the narrowing of the aortic valve opening—the opening between the lower left chamber of the heart (left ventricle) to the aorta.

As the National Library of Medicine’s MedlinePlus explains, the aorta is the main artery from the heart to the rest of the body. Aortic stenosis restricts blood flow. Depending on the severity of the restriction, a person can experience a variety of symptoms, including:

  • Shortness of breath
  • Chest pain, pressure or tightness
  • Syncope (fainting)
  • Palpitations, pounding or other noticeable heart beats
  • Fatigue upon exertion

Because aortic stenosis restricts blood flow, the heart has to work harder to pump oxygen-rich blood to the rest of the body. Over time, this overworking can result in thickening of the left ventricle walls and/or weakening of the heart muscle.
