The aorta is the main artery carrying oxygen-rich blood from the heart to the body. After each heart beat, the valve closes tightly to prevent blood from flowing backwards into the heart. Aortic insufficiency occurs when the aortic valve does not close tightly enough.

  • Acute aortic insufficiency —symptoms develop rapidly, and in severe cases, immediate surgery may be needed
  • Chronic aortic insufficiency —symptoms develop over the course of many months or years
