ABSTRACT
Fetal echocardiography represents a major part of fetal cardiology, a new and exciting field of perinatal medicine. The use of echocardiography enables confirmation of normal heart anatomy and physiology, detection of structural malformations, follow-up of functional abnormalities and the monitoring of invasive therapeutic interventions. These diagnostic capabilities are not restricted to singleton gestations; fetal echocardiography also has specific goals when used in multiple pregnancies (Table 42.1). In the usual circumstance, multiple pregnancies are referred for targeted cardiac examination following an obstetric screening which detects a cardiac problem. However, there are also numerous maternal and fetal conditions (listed in Table 42.2) which indicate a comprehensive cardiac scan.
