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.

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.

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.
  • 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.

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, as well as ensuring mothers experience fewer complications from fetal therapies, labor and delivery.

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.

Bringing together the brightest minds to innovate HLHS treatments

As one of only five centers in the country – and the only center in the region – participating in Mayo Clinic's HLHS Consortium, we are leading the way to find solutions for patients with HLHS. Through our Fetal Cardiology Program, pregnant women with a fetal HLHS diagnosis have the opportunity to participate in groundbreaking clinical trials studying the use of cell-based regenerative therapy to transform the lives of their children born with HLHS.

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.

Timing and indications for delivery following laser ablation for twin-to-twin transfusion syndrome

Laser photocoagulation can improve survival and reduce complications for twin pregnancies affected by twin-to-twin transfusion syndrome (TTTS), but prematurity remains a major source of neonatal morbidity and mortality for these patients. To better understand the indications and factors that influence premature delivery after laser ablation in babies facing TTTS, Michael Zaretsky, MD, and his team collected delivery information from 847 patients from 11 centers within the North American Fetal Therapy Network. This study determined that premature delivery, which on average occurs 10 weeks after laser photocoagulation and at 31 to 32 weeks gestational age, is primarily the result of spontaneous labor, preterm premature rupture of membranes and the status of the donor fetus. Researchers also found that placental abruption was a frequent complication causing early delivery.
