Filter by:This is a retrospective study. The investigators shall review the angiography data of 1200 consecutive cardiac catheterizations of children and babies with CHD (Congenital Heart Disease) since 1998 till now. Coronary artery origin and course will be evaluated in relation to the morphologic cardiac anomalies. Coronary artery anomalies will be described and statistical analysis will be performed.
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.
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.
Cardiac surgery requiring use of a heart-lung machine, also known as cardiopulmonary bypass (CPB) can induce abnormalities in blood coagulation (clotting) that lead to excessive blood loss during and after operation. While of significant concern in adults, this problem takes on even greater importance in children due to the simple fact that they have a smaller blood volume. It is well known that if a child has previously undergone a heart operation, they are at increased risk of bleeding should more cardiac surgery be required ("reoperation"). The processes regulating blood coagulation are extraordinarily complex, and little is known about the exact mechanisms that contribute to the increased bleeding associated with cardiac reoperation in children. Rotational thromboelastometry (ROTEM®) is a technology that can provide, at the bedside, detailed information about coagulation abnormalities. While not currently approved for general use in the United States, in Europe ROTEM® has been used to guide administration of the blood products in surgery based upon determination of specific coagulation abnormalities. Importantly, there is now evidence that guidelines for transfusion therapy based on ROTEM® reduce transfusion requirements thus decreasing patient exposure to blood products. Whether the use of ROTEM® has potential benefit for pediatric cardiac surgical patients has not been studied. Accordingly, the present study was designed to provide preliminary data comparing coagulation profiles between children undergoing cardiac reoperation to those having primary procedure. The investigators hypothesize that ROTEM® analysis will detect a pattern of impaired coagulation in children undergoing reoperation. The overall objective of the four assays of ROTEM® analysis therefore, is to provide information that can be used to devise a rational transfusion protocol for pediatric cardiac surgical subjects.
The investigators have recently evidenced the presence of antibodies to endothelial cells and fibroblasts in patients with idiopathic or SSc-associated PAH. The investigators also have identified several target antigens of anti-fibroblasts antibodies. The objective of this study is to further investigate for the presence of antibodies to endothelial cells and fibroblasts in patients and characterize the antigen specificity of autoantibodies in patients with different types of non idiopathic and non SSc-associated PAH, such as PAH associated with HIV infection, porto-pulmonary hypertension, congenital heart diseases, systemic lupus erythematosus, mixed connective tissue disease and Sjögren's syndrome
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.
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.
For this study, blood and tissue samples will be collected in order to perform genetic testing to help researchers gather information about this disease and how and why it affects some patients more than others.
