Mitral Stenosis (Re-release)

The Rx Bricks Podcast

Mitral stenosis (MS) is a narrowing of the mitral valve. In the normal cardiac cycle, the heart relaxes during diastole and allows blood to flow from the left atrium to the left ventricle through the open mitral valve. When the mitral valve is narrowed, blood flow becomes restricted (Figure 1). Excess volume and pressure build up in the left atrium, while forward flow to the left ventricle decreases.

After listening to this AudioBrick, you should be able to:

• Define mitral stenosis.
• List and explain the common causes of mitral stenosis.
• Describe the clinical presentation and diagnosis of mitral stenosis.
• Describe the treatment of mitral stenosis.

You can also check out the original brick from our Cardiovascular collection, which is available for free.
