This is an ultrasound test in which the structure of the fetal heart is examined.
A pediatric cardiologist usually performs it. It is usually performed between the
22nd and the 24th week of gestation in cases where a system scan indicates a suspected
heart defect.
It is also done in cases where the parents have a high risk of having an infant
with a heart defect. Increased risk for a heart defect is defined as when one or
both of the partners has a history of such a condition; a previous fetus or child
had or has a heart defect, or where signs are present, such as excess nuchal translucency, etc., that are indicative
of a syndrome which has a heart defect as one of its manifestations.
