Hi!
You might be developing what is called congestive heart failure. This will cause a fluid build up in your body which will cause fluid in the lungs and the cough you are describing. When you lay down, the fluid pools in your lungs rather than having the gravity to pull it down into your legs.
This is fairly common in people with a heart murmur.
The good news is that this condition is very easily treatable and controlled with a doctors guidance. Please make an appointment for a good check up soon.
