ABSTRACT
Introduction Technical advances in ultrasound technology over the past decade and the introduction of fetal echocardiography into the prenatal ultrasound examination have further improved the antenatal detection of congenital heart disease (CHD). Nevertheless, cardiac anomalies are the most frequently overlooked lesions during prenatal ultrasound evaluation, and this has profound medical, psychological, socioeconomic, and medicolegal consequences. There are several controversial issues in this field, and the usefulness of fetal echocardiography as a screening instrument in unselected populations has remained a matter of debate.
