Congenital heart disease, prenatal diagnosis and management.

Among congenital malformations, heart defects are the most common type of anomaly, and these are associated with a high perinatal, longterm morbidity and mortality. The objective of this update was to review the rate of prenatal detection, screening characteristics throughout the pregnancy, in both the first and second trimesters, indications for advanced echocardiography, and to establish a management algorithm in case of prenatal diagnosis of a congenital heart disease. Potential invasive and non-invasive tests and obstetric follow-up will be discussed here. Finally, the main characteristics of fetal therapy in heart anomalies will be reviewed, both cardiac interventions and intrauterine treatment of arrhythmias. Sociedad Argentina de Pediatría.
