Comparing cord clamping times for newborns with congenital heart disease

Official title: CORD-CHD: Clamp OR Delay Among Neonates With Congenital Heart Disease

Run by Nationwide Children's Hospital · NCT06153459 · Data updated 2026-11-12

This study is testing whether clamping the umbilical cord for 30 seconds or 120 seconds after birth helps newborns with congenital heart disease have better health and development.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are term-born infants with a prenatal diagnosis of congenital heart disease rated 3-6 on the Fetal Cardiovascular Disease Severity Score.

Probably not a fit

Patients without a prenatal diagnosis of congenital heart disease or those rated below 3 on the FCDSS may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to compare two different timepoints for clamping the umbilical cord in term-born infants diagnosed prenatally with congenital heart disease (CHD). Participants will be randomly assigned to either delayed cord clamping at 120 seconds or 30 seconds after birth. The study will assess health outcomes and neuromotor development at various postnatal ages using standardized assessments and questionnaires. The goal is to determine which clamping time leads to better overall health and developmental outcomes for these infants.

Why it matters

Potential benefit: If successful, this study could improve health and developmental outcomes for newborns with congenital heart disease.

How similar studies have gone: Other studies have explored cord clamping practices, but this specific comparison of timing in the context of congenital heart disease is novel.

Show full inclusion / exclusion criteria
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

Exclusion criteria are listed below and will be confirmed prior to randomization:

Exclusion Criteria for Pregnant Individuals:

1. Pregnant individual is a gestational carrier or surrogate.
2. Compromise of the pregnant individual (e.g., vasa previa, placental accreta with hypotension, placental abruption, amniotic fluid embolism, uterine rupture, uterine inversion, disseminated intravascular coagulation), as determined by local care team

\[NOTE: There is no limitation on pregnant individual's age\]

Fetal Exclusion Criteria:

1. Fetal demise or planned termination of pregnancy prior to randomization
2. Tachyarrhythmia requiring transplacental therapy
3. Fetal hydrops, severe
4. Planned fetal surgery
5. Diaphragmatic hernia, omphalocele, gastroschisis, intestinal atresia
6. Major chromosomal defects (e.g., Trisomy 13, 18) identified prenatally; Trisomy 21 is allowed
7. Disease or disorder impacting candidacy for neonatal cardiac interventions
8. Parents choosing to limit treatment

Pregnancy Exclusion Criteria:

1. Delivery planned at an institution not affiliated with or does not refer to a CORD-CHD participating site
2. Participation in another prenatal interventional study that influences cord clamping or perinatal morbidity or mortality
