Filter by:The objective is to the amount of protein infants require after cardiopulmonary bypass surgery.
Background: - Currently, heart catheterization procedures are guided by X-rays. Researchers are developing new techniques to perform heart catheterization without the use of X-rays by investigating possible uses of magnetic resonance imaging (MRI) scans. To study these uses, researchers are interested in performing a part of the standard X-ray catheterization procedure using MRI on individuals who are scheduled to have heart catheterization. Objectives: - To examine the safety and feasibility of right-heart catheterization using MRI-guided catheters. Eligibility: - Individuals at least 21 years of age who are undergoing a medically necessary heart catheterization procedure. Design: - The research MRI procedure will be performed either before or after standard X-ray guided heart catheterization. - Participants will be transferred from an X-ray table onto an MRI table and advanced into the scanner. Under MRI guidance, a MRI-compatible catheter will be used to measure blood pressure and blood oxygen levels in the heart, and MRI scanning will be performed for approximately 30 minutes.
Children with Cancer or congenital heart disease (CHD) experience complex, physical, psychosocial and behavioural symptoms and problems due to the illness, treatment, and medical procedures. To help children cope with their problems and prevent psychological distress, the investigators developed SiSom, a support system to help children with cancer or CHD report their symptoms and problems in an age-adjusted manner on a touch-pad, portable computer. This quasi-experimental study with 202 children age 7-12 with CHD or cancer will test the following hypotheses: When children use SiSom to report their symptoms and problems, and this information is provided to their clinicians in their outpatient consultations: - Children and parents will experience less anxiety. - Children and parents will be more satisfied with the outpatient visit. - There will be greater congruence between children's reported symptoms and problems and those addressed by their clinicians as evidenced in documented patient care. To better understand the mechanisms by which these effects may occur, the investigators will also explore: - Differences between control and experimental groups in patient-provider communication in terms of instrumental and affective behaviour, participation, initiative and person addressed; - The relationships among outcomes of patient-provider communication, congruence between patients' reported symptoms and those addressed by their clinicians and children's and parents' anxiety and satisfaction; and how these relationships differ between treatment and control conditions. Finally, the investigators will investigate time requirements, ease of use and usefulness of SiSom by children and clinicians. For analyses the investigators will use inferential statistics and qualitative analyses of the video-taped consultation sessions. This study will contribute to improving patient-centred care for a particularly vulnerable population, and to a better understanding of the triadic communication and interactions among child-parent and clinician.
Remote Ischemic Preconditioning (RIPC) is a treatment that may be associated with improved outcomes after cardiac surgery. It can be elicited noninvasively by using a tourniquet to elicit transient ischemia over a lower extremity. It is thought to promote anti-inflammatory and cell survival pathways, and thus protect remote organs against future ischemic injury. We hypothesize that compared to sham treatment, RIPC will be associated with decreased post-operative acute kidney, myocardial, and lung injury.
The current proposal tests the central hypothesis that acetaminophen will attenuate the oxidative stress response associated with cardiopulmonary bypass (CPB)-induced hemolysis in children undergoing cardiac surgery.
Congenital heart diseases (CHD) are the first cause of congenital malformations with an incidence of 8 for 1000 births. Within the two past decades prenatal diagnosis has had a great impact on CHD prevalence. France was the first country to show the impact of prenatal diagnosis on the lowering prevalence of the most severe CHD, the hypoplastic left heart syndrome. Since the 90's, great advances in pediatric cardiac surgery, intensive care and cardiac catheterization have led to lower mortality and morbidity in this population. Prevalence of " GUCH ", grown-ups with congenital heart disease has thus been significantly increasing. For all these reasons and as the investigators can also see in other many chronic diseases, new questions about the quality of life of these patients arise among patients, parents/future parents, doctors, patients associations, and public health organizations. In 2007 French government promoted a national public health plan for "improvement of the quality of life among patients suffering from chronic illnesses". First step of such a program is to correctly evaluate this quality of life. Indeed the concept of "quality of life" (QoL) remains subjective and difficult to appreciate and measure. Its analysis requires the use of validated questionnaires. Few questionnaires are available in Europe, especially in pediatrics. Few studies in this population have been led and no comparative study to a control randomized group has been published. The investigators study aims to analyze in the investigators tertiary care center in pediatric cardiology the QoL among 8 to 18 year old French patients with CHD using a validated questionnaire (Kidscreen™) and to compare it to same aged healthy children. The investigators secondarily intend to :- validate the French version of one reference pediatric QoL questionnaire used in most publications in the USA (PedsQL™). - compare the QoL to the severity of the CHD using a published semi-quantitative score.- compare the QoL to the severity of the CHD using the results of routine exercise tests (VO2 max) performed routinely in the investigators center. The investigators hypothesis are that :- Quality of life of most common and not severe CHD is close to that of healthy children. - QoL of severe CHD is not so well correlated to severity of CHD.- PedsQL™ is a simple questionnaire which can be used in France in routine follow-up of children with CHD.
All over the world 0.8 % of all live children are born with a Congenital Heart Disease (CHD) due to genetic end environmental causes. Advanced treatment and care has enhanced survival substantially, and adults with CHD are a growing population requiring continuous monitoring and care. Presently 25% of young adults acquire complicating Cardio Vascular Diseases (CVD) in young adulthood amongst other co-morbidities. It is known that adolescents with CHD are not as physical fit (PF) as their cardiac capability allows, most likely for reasons concerning safety, ability plus inactive everyday life. However, in 2006 The European Society of Cardiology states, that regular exercise at recommended levels can be performed and should be encouraged in all patients with CHD. Training programmes in hospitals have an effect on PF and Quality of Life (QoL) for the few, as most adolescents' find it impossible to fit into everyday life. It is the investigators hypothesis that an eHealth intervention, to facilitate intensive exercise in the patients' neighbourhood environs, may improve physical fitness more efficiently than standard lifestyle education. The purpose of the study is to create evidence to recommend an efficient, fun and safe cardiac rehabilitation programme to adolescents with CHD. Primary outcome measure Cardiopulmonary exercise capacity: Online V02 max bicycle test Secondary outcome measure Level of physical exercise: Actigraph and Questionnaire Tertiary outcome measure Quality of Life: PedsQl Prevail is a national prospective, randomized clinical trial including 216 adolescents aged 13-16 years, who have had cardiac surgery in childhood owing to complex CHD. The patients included are all recommended to be as physical active as their healthy peers and pursue the principle guideline from The National Board of Health: "All children and young people must be physically active for at least 60 minutes a day, preferably longer". Patients with mental retardation and FEV1 at baseline < 80% of predicted are excluded. The risk of participating in the purposed trial is not regarded as higher than everyday daily living. Results will be interpreted according to affiliation to health related fitness clusters.
It is well know that statins have been used to low cholesterol to prevent and treat coronary artery disease for many years. It was also reported that statins could protect endothelial function and cardiac function during coronary artery bypass graft. However, some results were controversial. Also, there is no clinical data available on statin cardiac protection during surgery in China where rheumatic heart disease is prevalent. Thus, the investigators are trying to see whether statins can protect heart injury during cardiac surgery in Chinese. Part of patients will receive statin treatment and part of will not before surgery in the study. Both patients' heart function will be measured and compared after surgery to determine whether statins can protect heart injury during heart surgery.
The purpose of this study is to determine whether children and adolescents 8-18 years of age with HLHS and related lesions who have undergone stage I palliation during infancy using an allograft patch demonstrate continued evidence of HLA antibody formation.
Prematurely born infants with ductal-dependent congenital heart disease (CHD) are at increased risk to develop necrotizing enterocolitis (NEC). Abnormal left to right blood flow through a patent ductus arteriosus can cause intestinal ischemia and compromise the gastrointestinal tract as a barrier to infection. In some infants, bacterial translocation leads to NEC which may result in death, intestinal perforation, cholestasis and, at the very least, feeding problems. Predicting which infants with CHD will develop NEC will potentially decrease the severity of disease if interventions were started earlier. Near-infrared spectroscopy (NIRS) allows determination of regional oxygen saturation levels in tissues such as brain, kidney, and as recently reported, intestine. This study will test whether or not decreasing intestinal oxygen saturations can predict the development of NEC in this at risk population before the symptoms become severe. NIRS probes will be placed on the forehead, flank and abdomen of eligible infants and regional oxygen saturations will be recorded prospectively and continuously with the clinical care team blinded to the data. The development of NEC and significant feeding problems will then be correlated with the regional oxygen saturations to determine whether decreased intestinal oxygen saturations predicted early signs and symptoms of NEC. We anticipate generating pilot data in 30 infants who meet inclusion criteria. Support of this research will be provided partially by Somanetics, the manufacturer of the INVOS regional oxygen saturation monitors. They will, however, have no control over the data generated by this study.
