Taking a Second Opinion to Heart

A second opinion and treatment at Seattle Children’s turned a devastating diagnosis before birth into hope for a bright future. Read how.

  • To diagnose or rule out fetal conditions, we use the most advanced imaging studiesgenetic testing and genetic counseling. We work with you to create a personalized plan informed by these tests. Our imaging techniques include: 

    • Fetal MRI (magnetic resonance imaging)
    • Fetal echocardiography. We can find congenital heart defects as early as 14 weeks of pregnancy.
    • Ultrasound
    • 3-D imaging 

    See data on the accuracy of our prenatal diagnosis of heart defects.

    We see families for many reasons, including: 

    • Risks or conditions found through genetic testing and genetic counseling
    • Abnormal results from prenatal screening tests. Tests may show a baby has a chromosome abnormality (like Down syndrome) or an increased risk for a condition such as a neural tube defect.
    • Suspected structural abnormalities, like heart defects, found by imaging studies during pregnancy
    • Health conditions of the mother or exposures during pregnancy that may affect the baby
    • Already had a child with a birth defect or genetic disorder that is known to have a greater chance of happening again
    • Desire for a second opinion
  • We make sure both you and your growing baby get the right care. Our team works closely with pregnancy care providers around our region. We bring together the specialists you need, all in one place. 

    • A dedicated prenatal coordinator will review your referral and customize your first visit to meet your individual needs. At your first visit, you will undergo advanced imaging and discuss the findings with your care team. Depending on your baby’s diagnosis, you will meet with:
      • Maternal-fetal medicine specialists from the University of Washington
      • Pediatric cardiologists

    • We regularly check your baby’s condition and provide treatment before birth as needed. For example, if a baby is diagnosed during pregnancy with a very fast, abnormal heart rhythm, we can treat the baby by giving medicine to the mother. For certain conditions, surgery during pregnancy may be an option. If the surgery cannot be done in the Seattle area, we help connect you to another center.
    • We work with your birth hospital to plan for a safe delivery and the specialized care your baby will need at birth and as a newborn. If your baby is likely to need complex care or surgery soon after birth, we arrange their transfer to Seattle Children’s.
    • Our transport team of doctors, nurses and respiratory therapists are national leaders in safely moving fragile newborns. They bring more than 500 critically ill babies to Seattle Children’s every year by ambulance, helicopter or airplane.
    • We plan for total expert care. This includes the best type of breathing support and special care your baby may need after birth.
  • Your team at Seattle Children’s will include specialists in newborn care (neonatologists) and others as needed, such as hearts (cardiology), lungs (pulmonary medicine) and the brain and nervous system (neurosciences). Your team at Seattle Children’s will include specialists in newborn care (neonatologists) and others as needed, such as hearts (cardiology), lungs (pulmonary medicine) and the brain and nervous system (neurosciences).

    • Fetal echocardiogram with cardiology consultation
    • Ultrasounds
    • Consultations with a doctor who specializes in high-risk pregnancies
    • Consultations that include cardiac surgery, pediatric surgery, ear-nose-throat (ENT), genetic counseling, genetic testing, neurodevelopmental, neurology, nephrology and urology. If you need to see more than 1 specialist, we work to coordinate your visits. 

    We provide fetal echocardiogram with cardiology consultation at 10 regional sites in Washington state, plus locations in Alaska and Montana. See our locations and contact information.

    You can arrange for fetal MRI (magnetic resonance imaging) at Seattle Children’s main campus in Seattle and our Bellevue clinic.

Request a Second Opinion

We offer second opinion consultations with our multidisciplinary team of experts in Seattle via telemedicine. The virtual format is helpful for families who live outside of Seattle and would benefit from connecting with the medical team prior to establishing in-person care in Seattle. For more information and to request a second opinion, email the Prenatal Clinic. A member of our team will contact you within 2 business days to begin coordinating your consultation.

Conditions We Care For

We diagnose and treat many conditions that are present before birth. If your developing baby has more than 1 condition, we coordinate with the specialists you need. Having accurate information can help you decide how best to manage your pregnancy. If you choose to continue your pregnancy, we monitor your baby’s condition and plan for their care.

  • Abdominal wall defects happen when the belly (abdomen) does not fully form as a baby develops during pregnancy. This causes a hole in the muscles and skin that cover a baby’s belly. There are 2 main types of abdominal wall defects. Gastroschisis is when a baby’s intestines are outside the body. An omphalocele is a sac covering organs that stick out of the belly button.

  • Sometimes imaging studies during pregnancy show a fetus has abnormalities of the brain or spine. Our neurodevelopmental pediatrician and pediatric neurologist review the available information and talk with you about the possible effects on your child. Learn about our craniofacial and neurosurgery outcomes, which are consistently among the best in the nation.

  • An arrhythmia is an abnormal heartbeat. This can mean the heart beats too fast or too slowly or with an irregular pattern. If an arrhythmia of the fetal heart is found during pregnancy, we recommend a fetal echocardiogram to learn more. Sometimes we give medicine to moms during pregnancy to treat the baby’s rhythm condition. Our heart surgery outcomes are consistently among the best in the nation.

  • Chromosomes are the parts of cells that carry genetic information passed from parent to child. Abnormalities in the number or structure of chromosomes can cause health problems. For example, in Down syndrome, extra genetic material causes a child to have developmental delays.

  • A congenital diaphragmatic hernia (CDH) is a hole in the thin muscle (diaphragm) that separates the chest from the belly (abdomen). Organs that should be in the belly can go through the hole into your baby’s chest. This affects how your baby’s lungs grow. Many babies with CDH have high blood pressure in their lungs and breathing problems. Read more.

  • If the heart does not form normally during pregnancy, a baby will be born with a congenital heart defect. There are many types. Our heart surgery outcomes are consistently among the best in the nation.

  • Every year, our Craniofacial Center treats hundreds of children with conditions from cleft lip and palate to rare syndromes that affect how the skull and face form. Sometimes an ultrasound during pregnancy shows a baby might have a craniofacial condition. Some families are at higher risk of genetic syndromes that affect the head and face. Our Craniofacial Center’s prenatal counseling team can help. Learn more about our craniofacial surgery outcomes, which are consistently among the best in the nation.  

  • Intestinal atresia happens when part of your baby’s intestine does not form completely. Instead of being an open tube, the intestine is closed off in 1 or more places. Sometimes parts are missing. This condition prevents food and poop (stool) from moving all the way through your baby’s body. Surgery is needed. Read more.

  • As a baby’s lungs develop before birth, sometimes an area of abnormal lung tissue forms. Lung lesions may form inside the normal lung or next to it. These conditions are often called CPAM (congenital pulmonary airway malformations). Finding these problems during pregnancy can help you and your healthcare team plan for your baby’s care. Some newborns need breathing support soon after birth. Read more.

  • Sometimes an ultrasound during pregnancy shows the baby has a large lump (mass) in the neck. Most common are lymphatic malformations that involve the body’s system for moving fluid (lymph system). Experts from Seattle Children’s Otolaryngology Department and Craniofacial Center meet with you during pregnancy. We assess whether the mass is likely to affect your baby’s ability to breathe at birth. We make a delivery plan with your childbirth team to support and treat your newborn.

  • Urologic conditions affect the system that makes, stores and drains pee (urine). Renal conditions affect the kidneys. We work with experts in Urology and Nephrology to care for babies with these problems.

  • Problems with the way a baby’s skeleton forms include clubfootdwarfism and missing bones. To arrange for a prenatal consultation, please contact Orthopedics.

  • Spina bifida is a problem with how the spine and neural tube develop into a baby’s brain and spinal cord. Spina bifida happens when there is an opening in the spine. Some of the spinal cord nerve material sticks outside. There are many neural tube defects, from mild to very serious. The most severe form, meningomyelocele, affects fluid spaces in the brain, muscle use in the legs, bowel and bladder control and cognitive developmentRead more about spina bifida (PDF). Our neurosurgery outcomes are consistently among the best in the nation.

Diagnostic Tools

We use these ways to diagnose or rule out fetal conditions and learn more about your baby’s condition:

  • fetal echocardiogram is a specialized ultrasound. It uses sound waves to view and make pictures of a developing baby’s heart. Usually, we do a fetal echocardiogram 18 to 22 weeks into the pregnancy. We offer a fetal echo as early as 14 weeks in some cases. These cases include having abnormal results from CVS (chorionic villus sampling) or if another child in the family had a major heart defect. We check again at 18 to 20 weeks.

  • Fetal MRI (magnetic resonance imaging) uses a strong magnetic field, radio waves and computers to take a series of detailed pictures of your developing baby. These pictures show your baby’s structures from different angles. Fetal MRI scans take about 20 to 40 minutes. They are safe and beneficial. They do not use radiation and have no known effects on your developing baby. Combining information from MRI and ultrasounds helps diagnose certain conditions during pregnancy.

  • genetic counselor helps answer questions about your health, your developing baby’s health or your family’s health. We talk about whether a health condition is passed from parent to child (inherited), why it happens, whether it can happen again and where to go for help. Read more.

  • We talk with you about tests that can be done before birth to help tell if a developing baby may have problems caused by changes in genes or chromosomes. If we recommend testing for you, we help arrange the tests. We do not do this testing at Seattle Children’s. Amniocentesis checks a small amount of fluid from the sac around the growing fetus. CVS (chorionic villus sampling) uses a small sample of cells from the placenta. Other tests during pregnancy use blood samples from 1 or both parents.

  • An ultrasound uses sound waves to view and make pictures of parts of the body. Maternal-fetal medicine doctors from the University of Washington and our ultrasound technicians know exactly what to look for during high-risk pregnancies.
