What is Aortic Stenosis?

About Aortic Stenosis:

• The Aortic valve keeps blood flowing from your heart’s lower left chamber (left ventricle) to the aorta, which is the main artery bringing blood from the heart to the body. 
• Aortic stenosis occurs when the aortic valve narrows and blood cannot flow normally. The condition may range from mild to severe.
  • Over time, aortic valve stenosis causes your heart’s left ventricle to pump harder topush blood through the narrowed aortic valve. 
  • The extra effort may cause the left ventricle to thicken, enlarge, and weaken.
  • If not addressed, this form of heart valve disease may lead to heart failure.
• Main Cause:
  • It is most commonly caused by atherosclerosis, a calcium buildup on the aortic valve over time.
  • These calcium deposits that often come with age make the valve tissue stiff, narrow, and unyielding.
• Symptoms:
  • Many people with aortic stenosis don't experience noticeable symptoms until the amount of restricted blood flow becomes greatly reduced.
  • Symptoms of aortic stenosis may include:
    • Chest pain
    • Rapid, fluttering heartbeat
    • Trouble breathing or feeling short of breath
    • Feeling dizzy or light-headed, even fainting
    • Difficulty walking short distances
    • Decline in activity level or reduced ability to do normal activities
• Treatment: Treatment of aortic stenosis depends on how severe the condition is. Treatment may include surgery to fix or replace the valve. 

Q1: What are arteries?

Arteries, a critical part of your cardiovascular system, are blood vessels that distribute oxygen-rich blood to your entire body. These tube-like vessels and the muscles inside them ensure your organs and tissues have the oxygen and nutrients they need to function. A condition called atherosclerosis can slow down blood flow through your arteries.
