Maternal and Fetal Medicine Research at the Colorado Fetal Care Center

Our research at the Colorado Fetal Care Center is driven by our belief that all children, even those not yet born, deserve the best chance at a brighter future. Through collaboration in ongoing multicenter trials, we're able to:

  • Offer some of the most innovative fetal therapies available today
  • Continually advance the standard of care for maternal and fetal medicine
  • Develop new therapies across the perinatal spectrum, from obstetrics to neonatology

Our research, in partnership with the University of Colorado School of Medicine, allows us to continually advance the standard of care for and treatments of infants, expecting mothers and high-risk pregnancies.

Current research has identified what causes a congenital diaphragmatic hernia. After searching for a solution, surgeons discovered a very small balloon called fetoscopic tracheal balloon occlusion. Learn how this helps in the growth of lungs.

Maternal and fetal medicine advancements

We're known around the world for groundbreaking innovations in fetal care research that are revolutionizing the care and treatment of both mother and child in high-risk pregnancies. Some of our team's most significant advancements include:

Revolutionizing myelomeningocele (MMC) treatment and repair

Our fetal surgeons are advancing and innovating prenatal treatment and repair for fetuses with myelomeningocele. In our efforts to improve MMC patients' quality of life, reduce complications and obtain better outcomes, our researchers have made several significant contributions, innovating the way fetal surgeons approach MMC. These efforts include:

  • Evaluated long-term flow patterns in the ductus arteriosus before, during and after fetal MMC repair to potentially reduce the incidence and/or severity of ductus arteriosus (DA) constriction and fetal cardiac dysfunction during open fetal surgery.
  • In an effort to reduce the need for shunting, our fetal surgeons became the first in the world to use 3D printing to prefabricate MMC patches before surgery.
  • Rony Marwan, MD, and his collaborator Daewon Park, PhD, bioengineered a minimally invasive alternative to open fetal surgery for spina bifida patients.

Improving outcomes for fetuses twin-to-twin (TTTS) transfusion syndrome

We are one of the country's highest volume fetal centers treating twin-twin transfusion syndrome. Our multidisciplinary team of maternal fetal medicine specialists, specialized physicians, fetal cardiologists and pediatric fetal surgeons collaborate to improve outcomes for laser photocoagulation, increase survival and decrease prematurity for babies with TTTS.

In an effort to guide future improvements in patient care, Michael Zaretsky, MD, collaborates with the North American Fetal Therapy Network (NAFTN) in managing a national registry of the complications and outcomes of monochorionic twin pregnancies.

Optimizing the health and delivery of babies with congenital heart disease (CHD)

Our work places us at the forefront of fetal cardiology and makes us leaders in caring for new lives. The Colorado Fetal Care Center team completed the first-ever Ex Utero Intrapartum Treatment (EXIT) to ventricular pacing procedure and continues to lead in innovative ways:

  • We are pioneering new techniques in regenerative medicine, including engineering a heart patch made of an infant's own tissue to improve outcomes for babies with hypoplastic left heart syndrome (HLHS). Using amniotic fluid collected at delivery, our team aims to create beating heart cells that can be used for future surgical repairs.
  • In the Heart Sounds at Home clinical trial, our researchers were the first to initiate fetal home doppler monitoring in the detection of fetal heart block for positive anti-SSA mothers.
  • Lisa Howley, MD, and Bettina Cuneo, MD, participated in a multicenter study aiming to increase parental education and improve transparency between clinical teams and parents. Using a series of questions developed by the Pediatric Congenital Heart Association (PCHA), we provide institution-specific answers for families regarding pediatric cardiac intervention outcomes, as well as short- and long-term expectations for neonates and infants with CHD.

Pioneering new technologies and treatments for babies with congenital diaphragmatic hernia (CDH)

Our Colorado Fetal Care Center is a national referral site for CDH, as the neonates with CDH who are discharged from our NICU have some of the best outcomes in the nation.

  • Our fetal surgeons conducted a clinical trial to improve lung growth for fetuses with CDH using fetoscopic tracheal balloon occlusion (FETO). We consistently see improved outcomes for patients with severe left-sided CDH.
  • In a multi-center study, our researchers standardized prenatal assessment of risk-stratification for fetuses with CDH.

Ongoing research in maternal and fetal medicine at Children's Colorado

Our researchers focus on improving care for the fetus, as well as ensuring mothers experience fewer complications from fetal therapies, labor and delivery.

Reducing the complications of mothers managing high-risk pregnancies

Our fetal surgery team constantly strives to reduce complications; following the groundbreaking Management of Myelomeningocele Study (MOMS), our fetal surgeons developed a modified hysterotomy closure technique that may reduce obstetric morbidity associated with prenatal MMC repair and other open fetal surgeries.

Other ongoing research efforts to improve the outcomes and reduce complications for expecting mothers include:

  • Exploring changes in maternal and fetal blood flow during fetal surgeries, labor and delivery to better predict possible hemorrhage or dangerous changes in mom's blood pressure.

What our maternal and fetal medicine research means for babies and expecting moms managing high-risk pregnancies

Our research at the Colorado Fetal Care Center aims to improve outcomes for babies with the highest-risk and rare fetal conditions.

At the heart of our research is a focus on each child's long-term quality of life, which influences everything we do and results in:

  • A better standard of living for our patients – babies, twins, moms and multiples
  • Improved care for the fetus
  • More innovative treatment options
  • Fewer complications for mothers from fetal therapies, labor and delivery

Our research means that here, you'll find expertise for the rarest conditions, and a multidisciplinary team dedicated to improving the outlook for our unborn patients and the mothers who carry them.

Saving "the sickest baby in the hospital"

Until Noah Lindsay, pulmonary AVMs had never been documented in a living CDH patient. Until our unprecedented CDH treatment, they thought he couldn't be saved.

Home From Hospital, Twins Spending First Christmas Together

For parents Charise and Mike Walters, this Christmas is one they will always treasure. Twins, Tommy and Emily were born last year, six weeks early; Tommy went home for Christmas, but Emily did not. She was born with congenital diaphragmatic hernia and was given only about a 20 percent chance of survival. She beat the odds and today, both Tommy and Emily are doing well, and will spend their first Christmas together.
