Filter by:During cardiopulmonary bypass (CPB) after heart surgery, a child's blood is exposed to many foreign entities. These conditions trigger the body's inflammatory response which results in leaky capillaries, increased swelling and possibly organ dysfunction. Since the early 1990's, modified ultrafiltration (MUF) has been shown to decrease excess swelling, reduce bleeding, improve heart function, and decrease hospital length of stay. Angiopoietins are a family of proteins necessary for both normal and abnormal blood vessel formation. They also appear to play a role in capillary leak. Though MUF has been shown to improve clinical outcome following CPB, there continues to be conflicting reports whether this is a result of the filtration of inflammatory proteins or simply from excess fluid removal. Since angiopoietins appear to play a role in both inflammation and capillary leak, the investigators hypothesize that the benefit seen after MUF is also secondary to its ability to filter out these proteins, especially angiopoietin-2.
Postnatal intestinal function in cardiac infants. The overall goal of this proposal is to address a widespread health problem in the pediatric cardiac infant population - poor postnatal growth - through a collaborative effort between pediatric cardiology, cardiothoracic surgery, neonatology, microbiology, and immunology. The hypothesis is that term neonates with complex congenital heart disease (CHD) who receive trophic breastmilk feeds in the pre-operative period will show improved gut function than neonates who were strictly NPO (nothing by mouth) in the pre-operative period.
This study compares clinical, self- reported and cost outcomes in children and adolescents treated with pulmonary valve implantation, percutaneous versus open surgical technique. Since cardiac surgery in children and adolescents affect the whole family, the experience of the patients and their closest relatives are recorded and analysed separately. Cost may be an important factor in the choice of technology (1). Hence, the present study also aims to compare savings in costs, percutaneous versus open technique, related to the individual, their family and society. 1.2 Research questions 1. Percutaneous pulmonary valve implantation or open heart surgery; what are the patients' and their closest relatives narrative experiences 2. Is there a difference in patient and their closest relatives reported outcomes, measured as health related quality of life, in patients with congenital pulmonary disease before the event, 1, 3, 6 and 12 months after percutaneous intervention versus open heart surgery approach? 3. What is the relationship between patient reported outcomes and clinical outcomes before, 1, 3, 6 and 12 months after the treatment? 4. Are there savings in costs related to the individual and their family and society between the two techniques?
The objective of this study is to evaluate the potential role of a cardiology clinic-based educational intervention for 15 to 17 year olds with congenital heart disease (CHD) and their parents, and to determine whether this intervention results in improved self-management skills (e.g., renewing medication prescriptions), teens having greater knowledge of their heart condition, and more teen and parent satisfaction with services. The results of this study will form the basis for a website that in turn may serve as an additional means of providing transition interventions. The results of this study may also be applicable to youth with other special health care needs.
The purpose of this study is to determine whether electroacupuncture preconditioning would provide protection against myocardial Ischemic-Reperfusion injury and systemic inflammation in children undergoing CPB for repair of congenital heart defects.
To evaluate the percentage of severe heart defect diagnosed with the use of color Doppler at a routine fetal scan in the second trimester of pregnancy
Congenital heart defects (CHD) are the most common major human birth malformation, affecting ~8 per 1,000 live births. CHD are associated with significant morbidity and mortality, and are second only to infectious diseases in contributing to the infant mortality rate. Current understanding of the etiology of pediatric cardiovascular disorders is limited. The Congenital Heart Disease GEnetic NEtwork Study (CHD GENES) is a multi-center, prospective observational cohort study. Participants will be recruited from the Pediatric Cardiac Genomics Consortium's (PCGC) centers of the NHLBI-sponsored Bench to Bassinet (B2B) Program. Biological specimens will be obtained for genetic analyses, and phenotype data will be collected by interview and from medical records. State-of-the-art genomic technologies will be used to identify common genetic causes of CHD and genetic modifiers of clinical outcome. To accomplish this, the PCGC will develop and maintain a biorepository of specimens (DNA) and genetic data, along with detailed, phenotypic and clinical outcomes data in order to investigate relationships between genetic factors and phenotypic and clinical outcomes in congenital heart disease.
Neonates with a congenital heart defect are often in need of early cardiac surgery. In complex congenital heart defects, cardiopulmonary bypass is usually employed, with or without deep hypothermic circulatory arrest (DHCA). The brain is especially vulnerable to ischemic injury, which puts neonates undergoing complex operations at high risk of neurodevelopmental disorders. Selective antegrade cerebral perfusion (ACP) instead of DHCA during these complex operations may contribute to less cerebral damage, but literature is not conclusive on this issue. Therefore, the investigators will perform a randomised controlled trial comparing DHCA and ACP in neonatal aortic arch reconstructions, focusing on cerebral damage and neurological outcome.
The purpose of this study is to determine whether inhaled iloprost is safe and effective in pediatric patients with pulmonary hypertension who are sick in the intensive care unit.
Quality of life and heart health are intimately connected to childhood physical activity participation (PAP). Physical activity is critical to childhood growth, development, learning, socialization, and quality of life and is an essential component of life-long heart health. Research by the investigators of this study and others has shown that low PAP levels are common among children with heart defects, and that these sedentary lifestyles are not related to exercise capacity, medical status or heart function.
