Cord Clamping Among Neonates With Congenital Heart Disease

Ki vehet részt

• 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.]
• Singleton gestation
• 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.]
• Consent for the participant and their infant
