What is the mitral valve?

The mitral valve is a small flap located between the two chambers on the left side of your heart. It sits between the left atrium (upper chamber) and the left ventricle (lower chamber).

The mitral valve acts like a door that opens to let blood flow from the left atrium into the left ventricle, then snaps shut to prevent blood from flowing backward. This one-way flow is essential for your heart to pump oxygenated blood efficiently to the rest of your body.

Connection to pulmonary hypertension:

When the mitral valve doesn't work properly, it can contribute to pulmonary hypertension. Two common problems include:

* Mitral regurgitation - The valve doesn't close properly, letting blood flow back into the left atrium
* Mitral stenosis - The valve narrows, requiring the left atrium to pump harder

These issues can cause blood to build up in your heart, putting pressure on the pulmonary arteries behind it. In some cases, mitral valve surgery may help reduce PH symptoms by repairing or replacing the damaged valve.
