Active clinical trials for "Heart Defects, Congenital"

Each year in the United States, thousands of babies are born with heart defects. Women who take folic acid during pregnancy have a lower risk of giving birth to infants with heart defects, but the reason for this remains unknown. This study will examine the relationship between genes, nutrition, and the occurrence of heart defects in infants.

The investigators aim to measure the impact of a rehabilitation program in congenital cardiology in terms of health related quality of life. The orginality of the rehabilitation program consists in its design : initial hospitalizationfor a short period of time (5 days) at the rehabilitation center, followed by 11 weeks of rehabilitation at home under the supervision of a specialized sports trainer.

This is a prospective, multi-center, open-label, PK and safety profile study of enteral digoxin in children <6 months old at time of enrollment, post-surgical or hybrid stage 1 palliation, but prior to surgical stage 2 palliation.

The aim is to conduct a prospective multi-centre international inception cohort study with an enrollment goal of 3,000 TOF patients and 2 year follow-up post-repair. The proposed sample size and methodology will result in statistically powerful results to allow for evidence-based change to current TOF surgical practices.

Pulmonary artery strapping is a surgical technique aimed at providing a palliative treatment to newborns suffering from congenital heart defects, characterized by an increase in blood flow and pulmonary blood pressure. The intervention consists of placing a band around the pulmonary artery. This band causes an artificial stenosis, therefore inducing a reduction of the pulmonary arterial pressure. It acts as a first step, preparing the ground for a future definitive repair intervention. It is mainly used in the context of septal defects, atrio-ventricular canal defects or uni-ventricular hearts. The complications linked to strapping include, among others, the erosion of the band in the artery lumen, its migration and the obstruction of the pulmonary artery, a pulmonary valvular insufficiency, the obstruction of the coronary artery and an ineffective strapping. The early mortality rate of pulmonary artery strapping after 1980 varies between 1.8% and 13.6%, while strapping readjustment rates oscillate around 20%. It is assumed that the mortality is linked to the nature of the cardial malformation (uni-ventricular or bi-ventricular) rather than the procedure itself. This retrospective study aims to evaluate the intra-hospital and extra-hospital mortality rate of pulmonary artery strapping, as well as the readjustment rate within two groups of patients: those benefiting from an uni-ventricular cardiac reparation and those benefiting from a bi-ventricular cardiac reparation. The aim is to determine the short term mortality rate of the intervention and the incidence of complications within the hospital, within the two groups.

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.

The purpose of this study is to assess for acute hemodynamic changes after implementation of noninvasive negative pressure ventilation (as compared with spontaneous respiration) in pediatric patients with Fontan failure using modern negative pressure ventilators

This study aims to determine what are some of the clinical characteristics and associations of Fontan patients who are doing well, as well as how accurate cardiology providers are at predicting the likelihood of future adverse event in their Fontan patients.

The aim of this study will be to evaluate vancomycin and cefoxitin blood levels during elective cardiopulmonary bypass (CPB) surgery in four pre-determined pediatric strata: neonates, infants, children weighting less than 40 kg and children weighting more than 40 kg.

PRISMIII(Pediatric Risk of Mortality III), PIM2(Pediatric Index of Mortality 2) and PELOD(Pediatric Logistic Organ Dysfunction) are frequently used for predicting mortality and morbidity in general pediatric ICUs(Intensive Care Units). However, the effectiveness of these scoring sistems in a specific group patients undergoing congenital heart surgery(CHS) is unknown. In this study, the investigators aimed primarily to evaluate the success of these scoring systems in predicting mortality and morbiditiy in this specific group and to compare the scoring systems with eachother, and secondly to evaluate the relationship of these systems with the STAT(STS-EACTS CHS Mortality Score) category
