The left ventricle of the heart is a muscular chamber. This chamber pumps blood from the heart to the entire body. The blood is pushed through the aortic valve into a major artery, called the aorta. After each heart beat, the valve closes tightly to keep blood flowing away from the heart.
If you have this condition, the valve does not close tightly. Blood leaks from the aorta back into the heart. Most people do not have symptoms and may not need treatment. But, you should talk to your doctor if you think you have this condition. You will need to have tests and get proper treatment.
Aortic insufficiency can be caused by:
These factors increase your chance of developing aortic insufficiency:
