Umbilical Cord Blood Collection and Processing for Cardiac Regeneration in Hypoplastic Left Heart Syndrome Patients


About this study

Cell-based cardiac regeneration has been the focus of acquired, adult heart disease for many years. However, congenital heart disease with severe structural abnormalities may also be reasonable targets for cell-based therapies. Interestingly, the pediatric heart is naturally growing and may be the most amendable to regenerative strategies. Therefore, identifying autologous cells (cells from the patient's own body) would be important to initiate these studies.

This study aims to validate the use of umbilical cord blood as a source of autologous cells for the purpose of cardiac repair of congenital heart disease. Cells will be isolated from the cord blood to help us determine the feasibility of collection, processing, and storage of these samples at the time of birth of infants with prenatal diagnosis of hypoplastic left heart syndrome. This study may be useful for the development of pre-clinical and clinical studies aimed at the long-term goal of repairing damaged heart muscle.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

  • Delivering party and/or expectant family is willing to sign Release of Information to request fetal echo text report diagnosing HLHS.
  • Parent(s)willing to be contacted 60 days after collection for follow-up screening questions regarding the health status of the HLHS baby.

Exclusion Criteria:
