Active clinical trials for "Heart Defects, Congenital"

One of the most common residual lesions in adult survivors of pediatric cardiac surgery is pulmonary valve disease, particularly regurgitation. Multiple studies have demonstrated that placement of a pulmonary valve in such patients, results in improved ventricular function and resolution of symptoms. However, the optimal prosthetic valve for use in the pulmonary position has not been defined. There are essentially three alternatives available: the stented bioprosthetic valve, stentless bioprosthetic "tube" grafts used to replace the entire right ventricular outflow tract and mechanical valves. All three of these valve options have been used in adults with congenital heart disease at Emory Healthcare and at Children's Healthcare of Atlanta at Egleston. The goal of this study is to evaluate and compare the indications and short and mid-term outcomes for these alternative therapies.

To identify genetic and environmental risk factors for congenital cardiac disease.

To identify genes involved in the pathogenesis of three types of congenital heart disease, atrial septal defects, paramembranous ventricular septal defects, and atrioventricular canal defects.

To determine genetic mechanisms responsible for congenital cardiovascular malformations.

Assessment of metabolic alterations in adult Fontan patients with a dominant left ventricle with the help of serum examinations (Metabolomics). The aim is to find a tool for the completion of the (semi-)invasive monitoring of Fontan hemodynamics.

Background: Acute kidney injury (AKI) is a common and serious postoperative complication in children with congenital heart disease. In this prospective cohort study, we tested the hypothesis that renal desaturation defined as a 20% decline of renal tissue oxygen saturation (SrtO2) from the baseline value is associated with AKI in infants undergoing ventricular septal defect (VSD) repair with cardiopulmonary bypass (CPB). Methods: Infants aged 1 months to 12 months and scheduled to undergo VSD repair with CPB were eligible. SrtO2 was monitored using a tissue near-infrared spectroscopy. Renal desaturation was defined as a decrease of SrtO2 measurement from the baseline value for more than 20% lasting for more than 60 s. The primary outcome was the incidence of AKI on postoperative 1-3 days according to the Kidney Disease: Improving Global Outcomes criteria. The secondary outcomes included different stages of AKI, duration of postoperative mechanical ventilation, duration of intensive care unit (ICU) and hospital stay, renal replacement therapy (RRT), and in-hospital mortality.

Aim #1: Define and determine the prevalence of pulmonary vascular disease and diastolic dysfunction as assessed by the gold standard of invasive hemodynamic cardiopulmonary exercise testing. Aim #2: Determine the role of rest-exercise echocardiography for the assessment hemodynamics in Fontan physiology. Aim #3: Evaluate the clinical impact of pulmonary vascular disease and ventricular diastolic dysfunction.

A single site, cross-sectional, pilot study of a mHealth application. Primary Objective This purpose of this pilot study is to evaluate mHealth adherence to a developmental application, Babysparks©, by parents of infants with complex congenital cardiac disease and single ventricle heart disease. Secondary Objective(s) -To determine the demographic and infant characteristics that correlate with mHealth adherence. -The rate of developmental progress of milestones while using the application will also be compared between infants with single ventricle cardiac disease and bi-ventricular cardiac disease. Research Intervention(s)/ Investigational Agent(s) Babysparks© developmental application is the main intervention with evaluation on feasibility of the mHealth application in a pediatric cardiology population. Study participants will be parents of infants with single ventricle and bi-ventricular complex congenital heart disease who underwent cardiac surgery in the first six weeks of life and are currently less than 18 months of age. Study Population There are approximately 150 new patients a year who have undergone cardiac surgery, with an additional 150 who are 18 months of age or less. Sample Size A maximum of 400 families/year Study Duration for Individual Participants Study participants will be monitored for a minimum of 6 months with the use of the BabySparks© App; to a maximum of 24 months of use of the app or when the child reaches a developmental age of 24 months, whichever occurs first.

Management of pregnancy and risk stratification in congenital heart disease (CHD) population might be challenging especially due to physiological haemodynamic modifications that inevitably occur during pregnancy. We aim to compare the accuracy of the main published scores including CARPREG II score in prediction of maternal complications during pregnancy in CHD patients.

Randomized controlled trial comparing femoral vs internal jugular insertion site of central venous catheters (CVC) in newborns and infants undergoing cardiac surgery. The experimental hypothesis is that the jugular insertion site is superior to the femoral in terms of catheter colonization.
