Filter by:A pilot study investigating the safety and feasibility of chronic maternal hyperoxygenation in the setting of fetal congenital heart disease
To demonstrate the safety and effectiveness of the Edwards Alterra Adaptive Prestent in conjunction with the Edwards SAPIEN 3 Transcatheter Heart Valve (THV) System in subjects with a dysfunctional right ventricular outflow tract/pulmonary valve (RVOT/PV) who are indicated for treatment of pulmonary regurgitation (PR). Following completion of enrollment, subjects will be eligible for enrollment in the continued access phase of the trial.
The objective of this study is to improve the diagnosis level of fetal congenital heart disease by the multi-center collaboration in China.
The goal of the Fontan Imaging Biomarkers (FIB) study is to identify the associations of blood and urine biomarkers to imaging parameters of ventricular mechanics.
The purpose of this study is to evaluate the safety and effectiveness of the TPV in patients with pulmonary valve dysfunction.
The primary goal of this study is to systematically describe early neurodevelopment using a complementary set of observational and neurophysiological measures that may predict cognitive and motor delays earlier than currently possible for infants with Complex Congenital Heart Disease (CCHD).
To examine retrospectively whether transcatheter closure of the interatrial septum leads to myocardial injury and to determine the mechanism.
Cardioplegic arrest is an essential part of cardiac surgery which aims to allow myocardial preservation and minimise myocardial swelling ,while providing a motionless and bloodless field ,.Blood cardioplegia has proven its efficacy for several decades and surgeons are still preferring to use it for myocardial protection of paediatric cardiac surgery ,although it is thought to be more time consuming since it is given with interrupted doses, . Even when advancement has came along the field of myocardial protection and cardioplegia solutions with the introduction of Bretschneider Histidine-Tryptophan-Ketoglutarate solution ,custodiol ,in 1970 ,which is given as a single dose and believed to be convenient, simple to deliver , and less time consuming . Many Surgeons haven't change their practice possibly due to paucity of studies comparing cardioplegia solutions in paediatric cardiac surgery and conflicting reports regarding the superiority of different cardioplegia solution.The investigators aim to provide evidence that will help paediatric cardiac surgeons to choose the optimal solution for their practice .
Persistant hypoxemia in the newborn confers, even isolated, an abnormal clinical situation, that needs to be addressed for an adequate diagnosis and an optimal treatment. If during the first hours of life, hypoxemia is frequent and often transient, beyond that, it is necessary to search the various etiological conditions such as a critical congenital heart disease (CCHD) or a non cardiac affection (sepsis, anemia, respiratory disease). Newborn pulse oximetry screening identifies babies with critical congenital heart disease (CCHD) based on the rational that they frequently have a degree of hypoxemia that may be clinically undetectable. CCHDs are life-threatening forms of congenital heart disease (CHD) occuring in 2-3/1000 live births but accounting for 3%-7.5% of infant deaths. Early detection is beneficial because of acute collapse, if not resulting in death, is associated with a worse surgical and neurodevelopmental outcome. Currently, screening for CCHD involves antenatal ultrasound scanning and post-natal physical examination. Although antenatal detection rates have improved over recent years and can be as high as 70%-80% in some centers, this is not consistent. Indeed, in "Nouvelle Aquitaine" overall <50% of CCHDs are detected before birth. In addition, up to a third of infants with CCHD may be missed on post-natal examination. Pulse oximetry screening can help to close the "diagnostic gap' that is, increase the detection of babies who slip through the current screening net. Several large European studies and a subsequent meta-analysis have shown that pulse oximetry screening is a highly specific (99.9%) and moderately sensitive (76.5%) test which increases CCHD detection rates. The high specificity results in a low false-positive rate 0.05% to 0.5%. But those babies with a Positive Test, if they may not have CCHD, they may be diagnosed with other causes of hypoxemia (congenital pneumonia, sepsis, persistent pulmonary hypertension,...). As with CCHD, delayed recognition of these conditions can result in postnatal collapse and significant morbidity and mortality. It is also more useful to consider these conditions as secondary targets of screening and to remember they constitute 30%-70% of false positives. In 2011, the US Health and Human Services Secretary recommended that pulse oximetry screening for CCHD be added to the Recommended Uniform Screening Panel. In Europe, implementation is advanced in such countries as North European Countries, and Switzerland. There isn't yet any European guidance. In France, the implementation is limited to local and transient experiments. The feasibility, usefulness and cost-effectiveness of routine pulse oximetry screening have not been evaluated so far. The French setting has two specificities : 1/ the antenatal detection rate is considered to be rather high. 2/ in contrast to a lot of other European countries, early discharge from the maternity ward before 48 hours of life is not common, decreasing the risk of discharging a baby with undiagnosed CCHD, but not saving babies from collapse. - The Investigators hypothesis is that routine pulse oximetry screening in asymptomatic newborns would allow to reduce the incidence of complications related to CCHDs as well as those related to non cardiac pathologies for a reasonable cost for the French Health Care System.
In the landmark Boston Circulatory Arrest Study, neurologic and developmental status was measured following infant heart surgery and then prospectively at ages 1, 2.5, 4, 8, and 16 years, with findings of significant neurocognitive deficits and brain MRI abnormalities regardless of operative management. To date, no study has evaluated the neuropsychological and neuroimaging antecedents and correlates of well-being in adults with congenital heart disease, a population now >1 million and projected to grow at 5% per year. The investigators propose to study the Boston cohort at ages 24-29 years to assess the associations of adult well-being with childhood and adolescent executive function, other measures of mental health and cognitive function, adolescent brain MRI findings, and clinical variables; findings will guide the design of interventions in childhood to optimize outcomes in adults with congenital heart disease.
