Active clinical trials for "Heart Defects, Congenital"

OBJECTIVES: I. Determine the pharmacokinetics of exogenous liothyronine administered in children undergoing the modified Fontan procedure. II. Determine the liothyronine supplementation dose that counters the fall in serum liothyronine concentrations and provides the greatest potential myocardial benefit after the modified Fontan procedure. III. Evaluate the potential toxicity of exogenous liothyronine administered in children undergoing a modified Fontan procedure.

Nutritional Prehabilitation Program and Cardiac Surgery Outcome in Pediatrics. A randomized controlled trial.

Transition is the planned movement of teens with chronic conditions from child-centered to adult-oriented healthcare. National bodies have published detailed guidelines about the importance of helping teens move to adult healthcare. However, there is no research regarding how to best organize and deliver Congenital Heart Disease (CHD) transition programs. Data is urgently needed. Therefore, the aim of this program is to develop research evidence that will better prepare health care providers to improve how they can help adolescents with transition. This project will determine whether a nurse-led transition intervention program is better at preparing teens with CHD to independently manage their medical care, compared to the care that is currently provided. The most important finding of this study will be whether or not these teens subsequently attend the adult cardiology clinic that specializes in CHD problems, and the timing of when they attend. Hypothesis: A transition intervention in combination with usual care, improved time to first Adult Congenital Heart Disease (ACHD) clinic attendance compared to usual care alone.

The psychosocial development of adults with congenital heart disease (CHD) can be challenged by many issues including family overprotection, impaired peer relationships, delayed progression into independent adulthood, and difficulties with career and future planning. One-third of patients have diagnosable mood or anxiety disorders and the prevalence of depression is 3 times that of the general Canadian population. Unfortunately, most adults with CHD and significant depression or anxiety do not receive mental health treatment. Despite an increasing awareness of the unique psychosocial concerns of this patient population by both health care providers and patients, there have been no interventions targeting psychosocial outcomes in the adult CHD population. Our quantitative and qualitative research suggests that patients themselves are very interested in psychological services that target their distinctive life experiences, are provided in a group setting, and emphasize coping and resilience. The overarching aim of this proposal is to assess the feasibility of a full-scale randomized controlled trial of a group intervention aimed at improving the psychosocial functioning, quality of life, and resilience of adults with CHD.

Ventricular septal defects (VSD) are the most common cardiac congenital heart defect (about 1/3 of patients with congenital heart disease). VSD management is related to hemodynamics and anatomical localization and the occurrence of complications. Small perimembranous VSD without pulmonary hypertension and without significant left to right shunting are tolerated, whereas large VSD with pulmonary hypertension require early surgical management in the first months of life. The management uncertainties concern the medium-sized perimembranous VSD causing a significant left-right shunt but without pulmonary hypertension, which are of variable treatment (surgical correction, percutaneous treatment, medical or abstention). There are no recommendations or consensus on the preferred indication of a therapeutic attitude. The Pediatric and Congenital Cardiology Subsidiary, within the French Society of Cardiology, set up an observatory of perimembranous VSD with significant shunting, without pulmonary hypertension the objectives of this study are: To study the incidence of cardiovascular events in perimembranous VSD and search for predictive anatomical markers of events. To study the evolution of echocardiographic and functional data of patients having percutaneous or surgical closure compared to patient managed medically. This observatory will provide a better understanding of the therapeutic algorithm in the management of VSD with pulmonary overload without pulmonary hypertension.

Most patients with complex congenital heart disease and cardiomyopathy from acquired heart disease have reduced exercise capacity. Exercise capacity is associated with respiratory muscle strength and function. If structured respiratory muscle training positively influences respiratory muscle function in patients with structural heart disease is not well known. The aim of this study is to investigate whether regular singing lessons and breathing exercises improve respiratory muscle strength in patients with congenital or acquired structural heart disease.

Participants under general anesthesia will be randomly treated with an adjusted dose dopamine or norepinephrine to elevate 10% of mean arterial pressure. Systemic hemodynamic data is recorded by PRAM and the change of cardiac index is compared between groups.

The purpose of this study was to investigate if repeated inflation of a blood pressure cuff applied around one leg causing mild ischemia ("remote ischemic preconditioning") could protect children operated for congenital heart disease from developing acute kidney injury.

The purpose of this study is to see if the study drug called spironolactone reduces fibrous (stiffening) in heart muscle tissue and improves heart function. Subjects from the study titled "Heart Failure in Congenital Heart Disease: the role of myocardial fibrosis" who have evidence of heart dysfunction and/or evidence of fibrosis (stiffening) in the heart muscle will be asked to take part in this study.

This hospital-based retrospective study reviewed patients who underwent surgery for CHD between 2017 and 2020 and analyzed the clinical features and outcomes associated with airway anomalies.
