Cardiac Care Group, LLC: Aortic Stenosis


Aortic stenosis is one of the most common and most serious valve disease problems. Aortic stenosis is a narrowing of the aortic valve opening. Aortic stenosis restricts the blood flow from the left ventricle to the aorta and may also affect the pressure in the left atrium. 

It’s important to note that many people with AS do not experience noticeable symptoms until the amount of restricted blood flow becomes significantly reduced. Symptoms of Aortic stenosis may include:

  • Breathlessness
  • Chest pain, pressure or tightness
  • Fainting, also called syncope
  • Palpitations or a feeling of heavy, pounding, or noticeable heartbeats
  • Decline in activity level or reduced ability to do normal activities requiring mild exertion

In addition to the symptoms of aortic stenosis, which may cause a patient to feel faint, weak, or lethargic, the wall of the left ventricle may also show muscular thickening because the ventricle must work harder to pump blood through the narrow valve opening into the aorta. The thickened wall takes up more space inside the lower heart chamber which allows less room for an adequate amount of blood to be supplied to the body, which in turn may cause heart failure. Early treatment can help to reverse or slow down the progress of this disease.
