I34.2: Nonrheumatic mitral (valve) stenosis
Your mitral valve has narrowed.
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 mitral valve is the valve between the left atrium and the left ventricle. Your mitral valve is no longer opening properly. If the mitral 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. You may be short of breath or have heart palpitations. You may also feel weak or tired. Sometimes, too, fluid collects in the legs.
On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.
- G: Confirmed diagnosis
- V: Tentative diagnosis
- Z: Condition after
- A: Excluded diagnosis
- L: Left
- R: Right
- B: Both sides
