Congenital heart disease pregnancy test can check out?

Most congenital heart diseases can be detected by pregnancy tests, but a few may be missed.

Most congenital heart diseases, such as ventricular septal defects, atrial septal defects, tetralogy of Fallot, etc., can be diagnosed by echocardiography at 18 -22 weeks of pregnancy. Some congenital heart diseases, such as smaller ventricular septal defects, patent ductus arteriosus, etc., may not be detected at 18-22 weeks of pregnancy, and doctors may recommend a second echocardiogram at 28-32 weeks of pregnancy to further evaluate heart development.

Some congenital heart diseases may not show symptoms until several weeks after birth, such as pulmonary valve stenosis, aortic coarctation, etc. Doctors may recommend a cardiac ultrasound after birth to rule out congenital heart disease.
