Fetal cardiology is the field of medicine that focuses on diagnosis and management of heart problems in the developing fetus as well as rhythm and cardiac problems that result from cardiac anomalies and obstetrical issues. There is increasing recognition of abnormal heart structure during routine obstetric scanning, allowing referral for specialist diagnosis and counseling. It is now possible to make accurate diagnosis of cardiac malformations as early as 12 weeks of gestation. Early diagnosis of a major cardiac malformation in the fetus can lead to prompt evaluation of genetic syndromes and analysis of the fetal karyotype and provide the parents with a comprehensive prognosis, enabling them to make the most informed choice about the management of the pregnancy. Early diagnosis allows physicians and families to better plan for a baby’s care before, during and after birth at a specialized cardiac care center for neonatal management. Prenatal diagnosis of congenital heart disease can improve the outcomes of infants with severe cardiac malformations. Congenital heart disease (CHD) is the most common congenital abnormality in the human fetus.
