I35: Nonrheumatic aortic valve disorders

I35.0: Aortic (valve) stenosis

The heart pumps blood through the body. Inside the heart are 4 chambers. There are 2 heart atria and 2 ventricles. Both heart atria and both ventricles are separated from each other by a partition. There are 4 valves in the heart. These valves ensure that the blood flows in the right direction. So they have to close tightly. They also have to open up fully so that the blood can be properly pumped out of the heart.

The aortic valve is the valve between the left ventricle and the main artery. Your aortic valve is no longer opening properly. If the aortic valve is not opening properly, the blood does not flow as well through the valve. The heart then has to work harder to pump enough blood to the body. You may have various symptoms as a result. One may be short of breath, and feel weak or tired. One may also feel dizzy or have chest pain.
