Congenital Heart Disease: Prenatal Diagnosis and Genetic Associations

Area of Science:

• Genetics
• Neonatal Medicine
• Prenatal Diagnosis

Background:

• Congenital heart disease (CHD) is a significant cause of infant illness and death.
• Genetic abnormalities are frequently implicated in congenital cardiac defects.
• Early prenatal diagnosis of CHD is crucial for optimizing neonatal care.

Purpose of the Study:

• To outline appropriate prenatal genetic testing strategies for fetuses with congenital cardiac defects.
• To identify specific cardiac defects linked to fetal aneuploidy and genetic syndromes.

Main Methods:

• A comprehensive literature search was conducted using MEDLINE.
• Keywords included "genetic testing," "microarray," and "congenital heart disease."
• The review incorporated various evidence types, including peer-reviewed articles, systematic reviews, and expert opinions.

Main Results:

• The review synthesizes evidence from diverse sources to inform genetic testing recommendations.
• Specific congenital cardiac defects associated with genetic abnormalities were identified.
• The importance of integrating genetic findings into prenatal care was highlighted.

Conclusions:

• Referral for genetic counseling and testing is recommended upon prenatal detection of CHD.
• Prenatal identification of genetic syndromes associated with CHD is vital.
• Effective communication among obstetric, genetic, and pediatric specialists enhances maternal and infant outcomes.
