Hi doctor,

I am 8 months pregnant. My obstetrician did an ultrasound, and according to her, my unborn child's heart size is at 64% when it should be less 50%. She advised me to have a 2D echo done, and I have not received the result yet. Is my child in danger?

Welcome to icliniq.com.

Thanks for the query.

Fetal echocardiography is not 100 percent reliable, so cardiac defects cannot be solely decided on imaging.

Comprehensive patient history, other illnesses, medicines taken during pregnancy, and family history are important. If the fetus is normal with regular movements and growth, and no signs of fetal stress, then one should be satisfied about the fetus. Only a reliable diagnosis can be made after the birth of the baby.

Echocardiography is repeated after birth if pre-birth echocardiography is abnormal.
