Institute for Maternal-Fetal Medicine - High Risk Pregnancy

From the moment a prenatal diagnosis is made, even before conception, the Institute for Maternal-Fetal Medicine at Sinai Hospital offers comprehensive care and support to women facing high-risk pregnancies. In addition to our board-certified maternal-fetal medicine (MFM) specialists, our expert staff consists of nurses, genetic counselors and a diabetes educator. We are committed to providing high-quality, compassionate care to women and their families—before, during and after pregnancy (including follow-up care for both mother and baby)—in a comfortable environment.

Using state-of-the-art technology, our specialists monitor and manage potential medical issues during high-risk pregnancies including:

  • Advanced maternal age
  • Birth defects
  • Fetuses at risk for stillbirth
  • Chronic conditions (such as high blood pressure and diabetes)
  • Multiple pregnancy (twins, triplets or more)

We offer:

  • Complete prenatal assessments and testing
  • Chorionic villus sampling and amniocentesis
  • Genetic counseling
  • Fetal therapy
  • Fetal well-being evaluations
  • MFM consultations before and during pregnancy
  • Genetic counseling before, during and after pregnancy

Our institute has earned American Institute of Ultrasound in Medicine ultrasound practice accreditation (first, second, third trimester and detailed fetal anatomy ultrasound), American Diabetes Association accreditation (diabetes in pregnancy program), and first trimester aneuploidy screening accreditation. You can learn more by viewing our patient forms and photo gallery.
