Outcomes in Patients and Their Closest Relatives Treated for Congenital Heart Disease With Catheter...

Congenital Heart Defects

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 Percutaneous pulmonary valve implantation or open heart surgery; what are the patients' and their closest relatives narrative experiences 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? What is the relationship between patient reported outcomes and clinical outcomes before, 1, 3, 6 and 12 months after the treatment? Are there savings in costs related to the individual and their family and society between the two techniques?

Amotosalen and Platelet Transfusion in Pediatric Heart Surgery

Congenital Heart Disease in Children

High level of security during blood transfusion has been achieved by donor selection and pathogen detection using serology or direct identification. Nevertheless, blood banking becomes hazardous during epidemic outbreaks or facing new pathogens. Amotosalen, a psoralen, targets nucleic acids and destroys them after ultraviolet exposure, resulting in inactivation of pathogens. Treatment inoccuity and efficacy have been demonstrated but preservation of platelet functions after treatment is still debated. Previous studies focused on hematological patients. There is no evidence for an increased requirement of transfused platelets to achieve platelet count target. Studies in heart surgery are lacking. The investigators perform a multicenter, retrospective, "before/after", controlled study in minor patients requiring heart surgery with cardiopulmonary bypass. One center (Strasbourg) uses Amotosalen-treated platelet concentrates since 2006 (control arm). This treatment becomes available in Bordeaux in October 2017 (intervention arm). There is two periods of inclusion: one "before" (January 2016 to June 2017) and one "after" (January 2018 to June 2019).

Using NPT to Evaluate Providing PPC as ELNEC-PPC WBT for Nurses

CancerCardiac Anomaly5 more

The purpose of this study is to explain the provision of palliative care at the end of life by the implementation of the ELNEC course, as WBT Program using the Normalization Process Theory, that focus attention on how complex interventions become routinely embedded in practice. In addition to, identify the changes implemented by the participant nurses (intervention group) in their clinical practice, after participating in WBT Program to provide Palliative Care alongside with usual care versus usual care only (control group) for children with life-limiting conditions or in the case of accidents/sudden death, at the end of life. And finally, provide findings that will assist in the interpretation of the trial results.

Evaluation of CARdiac Abnormalities by Echocardiography and MRI in Malnourished Patients Suffering...

Anorexia NervosaCardiac Anomaly

Anorexia nervosa is an eating disorder occurring in adolescent females, characterized by voluntary dietary restriction, intense fear of gaining weight, and disturbed body image perception. Anorexia nervosa is characterized by the potential severity of its prognosis. While complete remission occurs in about 50% of cases, up to 20% of patients will develop a chronic relapsing form that leads to social disintegration. Moreover, anorexia nervosa has the highest mortality rate among psychiatric diseases with a risk of death of up to 10%. 30% of deaths in anorexia nervosa are attributed to cardiac complications remaining insufficiently described, and their screening at a preclinical stage is still poorly codified. Echocardiography findings show reduced left ventricular mass, pericardial effusion or mitral valve prolapse ; in addition, systolic function appears to be preserved whereas a global diastolic dysfunction, estimated with trans-mitral flow and global longitudinal strain. While the interest of cardiac echography has been well established, only one study used MRI as a means of cardiac evaluation in anorexia nervosa: interestingly, local myocardial fibrosis is pointed and could potentially contribute to cardiac rhythm disorders. No study has yet used T1-Mapping MRI to evaluate if diffuse myocardial fibrosis is prevalent in this population group. The investigators conduct a transversal, observational, monocentric study whereby malnourished patients with anorexia nervosa and age- and sex- matched, normal weight, healthy volunteers will undergo a gadolinium-enhanced cardiac MRI. The primary objective of this study is to evaluate and compare the frequency of cardiac fibrosis in those populations. Other cardiac MRI parameters will be described and compared as secondary objectives. Moreover, non-cardiac parameters evaluated by MRI such as adipose tissue distribution in anorexia nervosa patients compared with controls. In addition, patients with anorexia nervosa, a clinical, morphological and biological evaluation, including anthropometric parameters, biphotonic absorptiometry, resting electrocardiogram, cardiac echography and classical biological markers of malnutrition, will be done.

Effects of Prostaglandin E1 Treatment on Pyloric Wall in Newborns

Pyloric Stenosis;AcquiredCongenital Heart Disease

Prostaglandin E1 (PGE1) has been used in the medical treatment of ductal dependent critical congenital heart disease in neonates. Apnea/ bradycardia, hypotension, hypokalemia, feeding difficulties, fever, jitteriness are the most important side effects of PGE1. Also gastric outlet has been reported. We aimed to determine effect of PGE1 treatment on pyloric wall thickness in newborn period. In this study, the side effect of increase of pylorus muscle wall thickness will be monitored with weekly ultrasonography. No intervention in the treatment, medical decisions and follow-up of these patients will be made. After reaching the sufficient number of cases (20 cases), increases in the pyloric wall thickness dimensions will be compared with statistical analysis. The number of cases was determined in accordance with the rate of hospitalization in our unit during the determined period (18 months).

Correlation Between 3D Echocardiography and Cardiopulmonary Exercise Testing in Patients With Single...

Single-ventricleCongenital Heart Disease

Congenital heart disease (CHD) is the leading cause of birth defects, with an incidence of 0.8%. Among CHD, univentricular heart disease or "single ventricle" is rare and complex. As a result of the improved patient care over the last decades, the number of children and adults with single ventricle is increasing significantly. Today, the main challenge is to ensure an optimal follow-up of these new patients in order to improve their life expenctancy as well as their quality of life (QoL). Currently, echocardiography and cardiopulmonary exercice test (CPET) are central in management of patients with single ventricle as part of good clinical practice guidelines. Single ventricle volumes and function are very difficult to asses with conventional echocardiography because of their complex geometry. Indeed, single ventricle size and morphology vary depending on the patient characteristics and on the initial CHD (before surgical repair). That's why conventional 2D echocardiographic parameters are not reliable for single ventricle assessment. Magnetic resonance imaging (MRI) is more effective in assessing single ventricle volumes and function. Nevertheless, MRI is not universally available, is not practical in many situations, is expensive, and is a relative contraindication in patients with pacemakers. Over the past decade, the use of the 3D echocardiography has increased. This is an available tool that can assess ventricular function and volumes in few seconds. Recent studies shown a good correlation between 3D echocardiography and MRI for assessment of ventricular volumes and function in patient with CHD and especially in those with single ventricle. Moreover, according to some authors, CPET parameters are strongly correlated with risk of hospitalization, risk of death, physical activity and quality of life, especially in patients with single ventricle. To date, there is no study performed about the relationship between 3D echocardiography and CPET parameters in patients with single ventricle.

A Pilot Study- Monitoring Cerebral Blood Flow in Neonates With Congenital Heart Defects

Congenital Heart DefectCerebrovascular Circulation

Congenital heart defects have an incidence of 9/1000 live births. Infants with congenital heart defects such as Transposition of Great Arteries / Hypoplastic Left Heart are at risk for brain injury because of concomitant brain malformations. Previous studies of cerebral MRI in infants with congenital heart defects showed that in 20-40% of cases there was preoperative brain injury and post operative with the same incidence. These findings are strongly associated with early and long-term neurodevelopmental injury. There is a necessity for a non invasive device who will monitor the cerebral blood flow during the hospitalization prior and post the cardiac defect repair surgery. The previous modal of the study device has been cleared for marketing by the FDA (k150268). The main goal of this study is to demonstrate that the new design of Ornim's c-FLOW 3310-P is easy to operate and effective in monitoring changes in cerebral blood flow in neonates as demonstrated in adults.
