Who will perform a fetal echocardiogram?
Fetal echocardiograms are noninvasive, performed by qualified sonographers and interpreted by a maternal-fetal medicine specialist in the field of fetal echocardiography.
When is a fetal echocardiogram performed?
Most fetal echocardiography studies are performed greater than or equal to 20 weeks of gestation for specific indications. Early fetal echocardiography may be performed between 11 to 16 weeks, and in such cases, a complete fetal echocardiogram follow-up will be recommended again at greater than or equal to 20 weeks of gestation.
What can I expect during a fetal echocardiogram?
Fetal echocardiography is painless and noninvasive, and you should experience no difference from a regular ultrasound, other than sounds from the ultrasound machine created by the flow of blood in the vessel or valve being sampled. You may be asked to hold your breath or remain still while the sonographer obtains the Doppler sample.
Where are fetal echocardiograms performed?
Fetal echocardiograms are performed in one of our private ultrasound suites. Coordination of appointments with a pediatric cardiologist is provided for those patients requiring additional cardiology services. Our department works in conjunction with Johns Hopkins Pediatric Cardiology to offer the very best in prenatal care to a mother and her unborn child.
