Brief summary

The goal of this clinical trial is to compare 2 different timepoints for clamping the umbilical cord at birth for term-born infants with a prenatal diagnosis of congenital heart disease (CHD). The main questions it aims to answer are: * Does Delayed Cord Clamping at 120 seconds (DCC-120) or Delayed Cord Clamping at 30 seconds (DCC-30) after birth lead to better health outcomes? * Does DCC-120 seconds or DCC-30 seconds after birth lead to better neuromotor outcomes at 22-26 months of infant age (postnatal)? Participants will be asked to do the following: * Participate in either DCC-120 or DCC-30 at birth (randomized assignment). * Complete General Movements Assessment (GMA) at 3-4 months of infant age (postnatal), complete questionnaires / surveys at this time. * Complete questionnaires / surveys at 9-12 months of infant age (postnatal). * Complete Hammersmith Infant Neurological Examination (HINE), Developmental Assessment of Young Children 2 Edition (DAYC-2), and questionnaires / surveys at 22-26 months of infant age (postnatal). * Permit data collection from electronic medical records for both the mother and infant study participants. Investigators will compare DCC-120 vs. DCC-30 to see which approach is more beneficial to both the mother and baby with CHD.

Detailed description

* AIM 1: Test the hypothesis that, among neonates with prenatally diagnosed significant CHD (ranking of 3 - 6 on the Fetal Cardiovascular Disease Severity Score \[FCDSS\]), DCC-120 results in lower global rank score (GRS), indicative of better health outcomes, compared with DCC-30. * AIM 2: Test the hypothesis that, among neonates with prenatally diagnosed significant CHD (ranking from 3 - 6 on the Fetal Cardiovascular Disease Severity Score \[FCDSS\]), DCC-120 will result in better neuromotor outcomes at 22-26 months postnatal than DCC-30.

Interventions

PROCEDUREUmbilical Cord Clamping at ~30 seconds

Care team will wait to clamp the umbilical between 1-\<60 seconds after birth. 30 seconds is the ideal time of clamping.

PROCEDUREUmbilical Cord Clamping at ~120 seconds

Care team will wait to clamp the umbilical cord between 60-180 seconds after birth.120 seconds is the ideal time of clamping

PROCEDUREUmbilical Cord Milking

For infants who need their cord clamped before the target in the DCC-120 group. Care team may milk the umbilical cord towards the infant four times. Cord milking should NOT be performed if the delay meets or exceeds 60 seconds. Umbilical cord milking will not be provided among participant-infant dyads in the DCC-30 group.

Inclusion criteria

are listed below and will be confirmed prior to randomization: 1. Fetal diagnosis of congenital heart disease (CHD) by prenatal ultrasound / echocardiography from local fetal ECHO, conducted on or after 18 weeks of gestation and prior to randomization. The study fetal diagnosis of CHD must be rated as 3 - 6 on the Fetal Cardiovascular Disease Severity Score (FCDSS), as determined by independent evaluators at the CORD-CHD trial ECHO Core at the Children's Hospital of Philadelphia (to determine final FCDSS eligibility for randomization). For each potential participant that has provided consent, the most relevant diagnostic prenatal ultrasound will be uploaded (shared) between 32 weeks of gestation and randomization for review by the ECHO Core. The ECHO Core will make the final FCDSS determination for eligibility status and stratification assignment.\] \[NOTE: A fetal diagnosis of CHD rated as 3 - 6 FCDSS per local review, including borderline cases, will be used to determine preliminary eligibility for consent. Among borderline cases, eligible patients will be included if there is a reasonable expectation of the need for surgery or cardiac catheterization during the birth hospitalization.\] 2. Singleton gestation. 3. Gestational age at randomization for impending deliveries between 37 0/7 - 41 6/7 weeks of gestation inclusive based on clinical information and evaluation of the earliest ultrasound determined using criteria proposed by the American Congress of Obstetricians and Gynecologists (ACOG), the American Institute of Ultrasound in Medicine and the Society for Maternal-Fetal Medicine. \[NOTE: Pregnant individuals who were admitted to the delivery hospital prior to 37 0/7 weeks of gestation remain eligible to randomize, provided they deliver within the 37 0/7 and 41 6/7 weeks "eligibility window". Alternatively, if an eligible dyad is randomized at or just prior to 41 6/7 weeks, they remain in trial.\] 4. Consent for the participant and their infant

Secondary

MeasureTime frameDescription
Neuromotor Outcomes at 3-4 months of age (Infant participant)3-4 months after birthGeneral Movements Assessment (GMA): The General Movements Assessment is used to identify absent or abnormal general movements in infants. General movements are spontaneous movements exhibited during fetal development and through the first 6 months of life after birth. Trained investigators will evaluate the infants general movements as: 1) Fidgety present; 2) Fidgety abnormal; and 3) Absent fidgety where "Fidgety present" is considered normal, and the other two outcomes are considered abnormal.
Impact of infant's congenital heart disease (Parents / Caregivers)3-4 months after birthQuestionnaire/Survey on the impact of infant's congenital heart disease upon the family dynamic; Impact on Family Scale - Revised: The Impact on Family Scale - Revised is a questionnaire for parents / caregivers used to evaluate perceptions of the impact of an infant's chronic medical condition (e.g., congenital heart disease) upon the family. The IFS-R uses a 4-point Likert-type scale (strongly agree to strongly disagree) for responses. High scores correlate with parental / caregiver stressors and psychiatric symptoms, poor infant health, and increased pediatric hospitalizations and/or health maintenance requirement, representing worse outcomes.
Neurodevelopmental Outcomes at 22-26 months (Infant participant)22-26 months after birthHammersmith Infant Neurological Exam (HINE): The Hammersmith Infant Neurological Examination (HINE) consists of 26 items that assess different aspects of infant neurological function. The maximal global (total) score is 78, divided among the following domains: cranial nerve function (maximum score 15); posture (maximum score 18); movements (maximum score 6); muscle tone (maximum score 24) and reflexes and reactions (maximum score 15). Higher scores indicate better expected outcomes.
Parental perspectives of outcomes (Parents / Caregivers)22-26 months after birthSurvey of parent / caregiver opinions of expectations and outcomes as it relates to their infant with congenital heart disease. This questionnaire will examine parental perspectives with regards to health and neurodevelopmental outcomes, as compared to those commonly used in pediatric medicine. For example, parents / caregivers may place greater emphasis upon their child being able to conduct physical activity as compared to how well they perform tasks (fine and gross neuromotor function). Additionally, parents may express concern for their infant being able to eat without requiring a feeding tube, or breathing without the need for assistance or additional oxygen support. The survey will also seek to determine areas in which parents / caregivers feel there is room for improvement as it applies to their infant. There is no formal "scale" for this survey, as responses are primarily open-ended, requiring descriptive content analysis.
Delivery Complications and Outcomes (Pregnant individual participant)Through hospital discharge (up to 1 month)Incidence of postpartum hemorrhage (defined as blood loss \>1L within 24 hours post-delivery)
