“What causes children to have a heart murmur?”
My 11 year old son was diagnosed with a mild heart murmur. What causes children to have a heart murmur?

Often, these are normal noises. The sound of blood flowing through the heart. If the child has something wrong with their heart (a hole or leaky/stenotic valve), blood flowing through that hole/valve can also cause them.
Most heart murmurs are innocent - normal blood flowing through normal pipes. You can also have a heart murmur from an abnormality of a heart valve or something like "a hole in the heart.” Your doctor can help decide if it is something that needs the attention of a pediatric cardiologist or not.
