Active clinical trials for "Heart Defects, Congenital"

Design: Observational - Cross study with followed up for 30 days. The Primary Objective is to realize a record that reflects a national overview of the role of cardiac catheterization in patients with congenital heart disease in hospitals distributed by geographic density of each region of Brazil.

This project will evaluate fluid balance and edema formation in children with congenital heart disease in need of a surgical procedure, The Fontan procedure. Surgery will make the child end up with a univentricular heart with one-chamber circulation ( Fontan circulation). This project will evaluate if these children has increased micro vascular leakage before surgery due to their congenital heart defect. The project will also investigate if the edema formation seen during cardiac surgery with the use of Cardio-Pulmonary Bypass (CPB) and hypothermia is caused by capillary leakage of plasma protein. The study hypothesis are Edema developed during heart surgery is caused by reduced colloid osmotic pressure gradient through the capillary membrane. The degree of micro vascular leakage in open-heart surgery is related to duration of CPB and hypothermia. Fontan circulation cause peripheral edema related to elevated central venous pressure and is not caused by increased micro vascular leakage of plasma proteins.

The goal of this study is to find out if there is any association between a mother's exposure to bacteria that normally causes "strep throat" and her baby's developing heart disease/heart defect.

Multi-center, observational, U.S.-based longitudinal program. Data will be collected prospectively for 3 years. Individual physician feedback will be provided on data collected with the purpose of improving the management of patients - quality enhancement research initiative (QuERI) process from adult patients enrolled with a history of repaired Congenital Heart Disease (CHD).

Background: Researchers do not know much about the causes of congenital heart disease (CHD). They do know that many factors play a role. Some factors are environmental. Some are genetic. But few specific factors have been identified. And researchers do not know how many involve genes. They want to study data that has already been collected from people with CHD and their families. Objectives: To identify genetic variations related to CHD. To study molecules related to vascular disease in order to learn new ways to treat it. Eligibility: People who already participated in the Pediatric Cardiac Genomics Consortium (PCGC) study Design: Researchers will study data that was already collected in the PCGC. There will be no active participants. Researchers will get access to the data through the coordinating center. They will not download data to local storage devices. The data will have no personally identifying information....

Congenital Heart Defects and NIRS

Congenital heart diseases are nowadays frequently treated in newborns. These congenital heart defects can directly affect the right ventricular ejection tract (RVOT), or sometimes indirectly, when the left ventricular ejection tract (LVOT) is replaced by the ROVT in a Ross operation. Originally introduced by Ross and Somerville in 1966, the reconstruction of ROVT by valved homografts is since then widely used.Pulmonary and aortic homografts then constituted the gold standard in conduit replacement between the right ventricle and the pulmonary artery (VD-AP). The increasing demand for homografts currently induces a shortage and unmet demands. This lack of availability, and the durability of homografts in young patients, has encouraged the search for alternative conducts.For example, in 1999, Medtronic® put a bovine jugular vein xenograft (VJB) on the market, the Contegra® conduct, as alternative for the homograft for RVOT reconstruction. This duct naturally has a central valve with three valvules, and there is on both sides of the valve a generous duct length allowing unique adaptation options. This conduit, however, is not perfect. Whether using Contegra® ducts or homografts, replacement is inevitable. The aim of this study is to compare operative morbidity and mortality when replacing Contegra® or homograft.

Surgeries of heart disease in adulthood can happen in two specific contexts: either for an asymptomatic anomaly, possibly coupled with the onset of symptoms later in life and tardily diagnosed and surgically managed either for a malformation treated in childhood and requiring a new intervention in adulthood. In recent years, the number of adult patients with congenital heart disease has been steadily increasing. Advances in diagnostic techniques and surgical treatments have enabled many children to reach adulthood. The number of these patients is now higher than the number of children with congenital heart disease. The number of these patients having had surgery in adulthood is also increasing. Congenital cardiopathies are numerous, ranging from simpler pathologies such as inter-auricular or inter-ventricular communication, to much more complex pathologies such as situations of univentricular hearts. The surgical treatments of these congenital heart diseases are classified into three groups: initial palliative surgery, initial curative surgery or iterative surgery. Palliative surgery aims to improve the clinical tolerance of the patient to the conditions of his pathology or to prevent complications. The curative surgery restores the physiological circulation, the iterative surgery treats a complication or a degeneration appearing after a curative surgery. Patients undergoing cardiac surgery frequently receive blood products transfusions during the preoperative, intraoperative, or postoperative periods. Several observational studies have shown that in cardiac surgery, the transfusion of blood derivatives is associated with an increase in post-operative morbidity and mortality. The objective of this study is to analyze the predictive factors of transfusion in congenital patients operated in adulthood at Brugmann University Hospital, depending on the type of surgery applied (palliative, curative or iterative). The secondary objective will be to assess whether there are any differences with the predictive factors identified in non-congenital patients undergoing cardiac surgery, which could potentially alter the transfusion approach in congenital patients.

Currently, both oral and written health education make certain assumptions about the health literacy of patients and their parents. The prevalence of health literacy issues is unknown in the adult congenital heart disease (CHD) population. Having a better understanding of a patient's and/or their parents' health literacy will help us develop appropriate education and teaching tools to meet the patient's and their parents' needs.

This study evaluates the association between perioperative echocardiographic Doppler findings and clinical outcomes in pediatric patients undergoing cardiac surgery. In our center, anesthesiologists perform transthoracic or transesophageal echocardiography during perioperative period routinely in children undergoing surgery for congenital cardiac disease. Echocardiographic findings include the doppler patterns of hepatic vein, portal vein, renal artery, renal vein and splenic vein before and after cardiopulmonary bypass. Portal pulsatility index, renal resistive index, and respiratory variations in peak aortic blood flow velocity and diameter of inferior vena cava are measured.
