Our cardiologists see patients with suspected and confirmed heart disease. Diagnosis and support can start even before children are born. Providing a state-wide service, the cardiologists travel to see families at remote clinics outside the Sydney region. Our links with specialist adult cardiologists ensures a smooth transition in care when children reach adulthood.
