Yesterday took dd to the drs (because she had a cold, and we monitoring her illnesses) anyway we have left with a referral to a cardiologist!
Completely took me by surprise (and tbh I'm freaking out!)
The referral says
"... Systolic murmur in the left sternal edge. Suspect possible mitral regurgitation"
Did some googling... Doesn't seem too serious? But still I'm stressing
