Damage to which structures may result in a heart murmur?

Damage to heart valves can lead to heart murmur.

Explanation:

Heart murmur refers to the sound of blood flow. The sound of flowing blood in the heart is usually not heard.

The heart murmurs can result due to two reasons that is either a damaged valve or any condition that causes the heart to beat at a faster rate.
