Response to: "Placenta insufficiency and congenital heart defects".

Congenital heart defects (CHD) affect around 1% of live births. In modern obstetrics, most CHD can be diagnosed in utero as long as fetal cardiac screening is done, which is a part of the mid-trimester anatomic ultrasound. In some centers, a fetal echocardiography examination can be done from the late first trimester onward.1 Prenatal diagnosis of CHD allows parental decision-making and the preparation for cardiac management after delivery. Although the survival rates for CHD have remarkably improved, they still are a leading cause of fetal/neonatal mortality due to birth defects.
