Baby referred for cardiologist

Kelly

So I took my daughter in for her one year check up and she is finally used to the pediatrician so she didn't cry hysterically. Well the pediatrician said when she was listening to her heart she heard a heat murmur and probably didn't hear it before because she was always crying. Anyone else have to take their child to cardiologist for this? What should I expect at the appointment? She goes July 22nd.
