Yes: Sonogram of heart- called echocardiogram will, detect most cardiac anomalies associated with down's syndrome.

Many are missed.: The best sonographers miss fetuses affected with Down syndrome. Only half will have a cardiac defect. The OK sonographers miss about 50%. Now, the best and most accurate screening test is not a fetal ultrasound, it is a blood analysis of fetal DNA in your bloodstream, done as early as 9 weeks0 days by one lab., 10w0d by 3 others, all 99.99% accurate. Confirmation by CVS or amnio recommended.

Many other birth defects can be detected with ultrasonography. The best ultrasonographers may detect may in the first trimester, and good monographers usually wait until 18 to 20 weeks. !0 years ago I presented the first case of diaphragmatic hernia and arterial obstruction sequence in an 11 week fetus, at the International Fetal Medicine and Surgery Society.
