NCT06711666
Prenatal Maternal Mental Health and Neurodevelopment in Congenital Heart Disease
Congenital heart disease (CHD) is the leading cause of congenital malformations, representing 1% of live births. Progress in surgical care have led to the dramatic increase in the population of children and adults living with heart disease. As survival is no longer a concern, long-term outcomes have become the major public health issue. Prenatal diagnosis of CHD requiring open-heart surgery can be a traumatic event for expecting mothers and fathers. In the general population, maternal mental health distress is associated with fetal disturbances in the hypothalamic-adrenal-pituitary system axis, restricted intrauterine growth and adverse outcomes in the offspring. It is unknown whether prenatal maternal psychological distress have an impact on neurodevelopmental outcomes in CHD. Our national study seeks to (1) characterize the impact of prenatal maternal psychological distress on neurodevelopmental outcomes at age 1 for children with CHD who undergo neonatal open-heart surgery; (2) investigate the sociodemographic and medical determinants associated with prenatal maternal mental health of women carrying a foetus diagnosed with complex CHD; (3) explore the mediating role of prenatal risk factors (i.e., sociodemographic, medical and maternal coping mechanisms) in the association of prenatal maternal mental health (i.e., distress, anxiety and depression) and neurodevelopment in children with CHD; and (4) explore the impact of paternal or the co-parent's mental health impact on neurodevelopmental outcomes at age 1 in children with CHD. This study is a non-interventional, prospective, and longitudinal study of prenatal maternal mental health and subsequent child's neurodevelopmental and behavioural outcomes. It includes a follow-up period from the 3rd trimester of pregnancy until the child's first year of life. It will include children with a prenatally diagnosed heart defect requiring open-heart surgery within the first weeks of life. Understanding and preventing the neurodevelopmental sequelae of heart disease diagnosed in-utero is a public health priority.

Intramyocardial Injection of Autologous Umbilical Cord Blood Derived Mononuclear Cells During Surgical Repair of Hypoplastic Left Heart Syndrome
Researchers want to better understand what happens to the heart when the stem cells are injected directly into the muscle of the right side of the heart during the Stage II palliative surgery for single ventricle patients with hypoplastic left heart syndrome (HLHS) or HLHS variant. Researchers want to see if there are changes in the heart's structure/function following this stem cell-based therapy and compared to children that have not had cell-based therapy.

Evaluation of Lomecel-B™ Injection in Patients With Hypoplastic Left Heart Syndrome (HLHS): A Phase IIb Clinical Trial.
The purpose of this study is to test whether Lomecel-B™ works in treating patients with hypoplastic left heart syndrome (HLHS) and to gather additional information about the safety of Lomecel-B. Lomecel-B contains human mesenchymal stem cells (MSCs) as the active ingredient. MSCs are special cells in the body that are able to change into other types of cells, such as heart, blood, and muscle cells. MSCs are found in various tissues of the body, such as the bone marrow, which is the spongy tissue inside of your bones. Lomecel-B uses MSCs from bone marrow of unrelated young healthy donors. These are called "allogeneic", and do not require donor matching to the patient.

Effect of Fetal Aortic Valvuloplasty on Outcomes
In one of the most severe congenital heart defects, hypoplastic left heart syndrome (HLHS), the left ventricle is underdeveloped and the prognosis is worse than in most other heart defects. The underdevelopment can occur gradually during fetal growth caused by a narrowing of the aortic valve. At some international centers, such fetuses are treated with a balloon dilation of the narrowed valve, but there is no scientifically sound evidence that this treatment is effective. The aim of this study is: 1/ to evaluate whether balloon dilation during the fetal period of a narrowed aortic valve can reduce the risk of the left ventricle becoming underdeveloped and the baby being born with a so-called univentricular heart (HLHS); 2/ to investigate whether such treatment improves the prognosis for this group of children with a very complex and severe heart defect and 3/ to also describe side effects and risks in fetuses and mothers of the fetal procedure.

Study of Intramyocardial Injection of Ventrix Bio Extracellular Matrix (VentriGel) to Assess the Safety and Feasibility in Pediatric Patients with Hypoplastic Left Heart Syndrome (HLHS)
The goal of this Phase I Open-Label study is to demonstrate the safety and feasibility of VentriGel injection in children with Hypoplastic Left Heart Syndrome (HLHS). The main questions it aims to answer are: * Whether VentriGel is safe in treating patients with HLHS * Whether there are any preliminary improvements in measures of cardiac function following Ventrigel injection
