The Sequencing for Detection in Congenital Heart Disease (SD-CHD) Study
What this study is about
This study is enrolling pregnant persons treated at Rady Children's Hospital fetal cardiology program with a prenatal diagnosis of congenital heart disease to look for genetic disorders in the fetus or unborn baby. Congenital heart disease (CHD) is a group of structural differences to the heart that represent the most common birth defect among liveborn infants world-wide.
View original scientific description
This study is enrolling pregnant persons treated at Rady Children's Hospital fetal cardiology program with a prenatal diagnosis of congenital heart disease to look for genetic disorders in the fetus or unborn baby. Congenital heart disease (CHD) is a group of structural differences to the heart that represent the most common birth defect among liveborn infants world-wide. CHD is the leading cause of birth-defect associated infant death. Prenatal detection allows for delivery planning, postnatal repair, specialized medications, and detailed counseling for parents. Up to one in three fetuses with CHD may have a genetic cause. In babies, knowing about genetic diseases helps patients and doctors provide the best care for their babies. If identified prenatally, this same knowledge may help participants prepare for their location of delivery, meet with specialists, and consider specialized treatments and medications that may be appropriate. The diagnostic yield and clinical utility of whole genome sequencing (WGS) in fetuses with prenatally detected congenital heart disease (CHD) will be compared to routine clinical testing in patients choosing amniocentesis or chorionic villus sampling. DNA will be obtained from fetal samples and biological parent blood samples and analyzed according to standard clinical interpretation guidelines. Results will be reported to healthcare providers and patients and measures of clinical utility will be collected. Additionally, measures of stress, anxiety, depression, and perceived utility of information will be assessed by validated survey tools. A historical cohort of patients electing for diagnostic procedures will be used as a comparison population.
Interventions
DIAGNOSTIC_TEST
Whole Genome Sequencing (WGC) from subject samples
Perform whole genome sequencing (WGS) on fetuses with prenatally detected congenital heart disease (CHD) who meet inclusion criteria. Assess diagnostic yield of WGS in CHD and effect of prenatal versus postnatal phenotype on diagnostic yield.
Primary outcome measures
Diagnostic yield of WGS in fetal congenital heart disease
Time frame: Anticipated 200 trios in 2 years
Trios with pathogenic or likely pathogenic sequencing results/ total number of trios.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
