INSPIRIS RESILIA Valve in Pulmonary Position

Pulmonary Valve DisorderCongenital Heart Disease

In this trial we intend to evaluate the safety and effectiveness of the INSPIRIS valve prothesis in the pulmonary position in patients of five years or older, with congenital or acquired pulmonary valve disease, requiring replacement of their native or prosthetic pulmonary valve.

Effect of Fetal Aortic Valvuloplasty on Outcomes

Congenital Heart DiseaseAortic Valve Stenosis2 more

In one of the most severe congenital heart defects, hypoplastic left heart syndrome (HLHS), the left ventricle is underdeveloped and the prognosis is worse than in most other heart defects. The underdevelopment can occur gradually during fetal growth caused by a narrowing of the aortic valve. At some international centers, such fetuses are treated with a balloon dilation of the narrowed valve, but there is no scientifically sound evidence that this treatment is effective. The aim of this study is: 1/ to evaluate whether balloon dilation during the fetal period of a narrowed aortic valve can reduce the risk of the left ventricle becoming underdeveloped and the baby being born with a so-called univentricular heart (HLHS); 2/ to investigate whether such treatment improves the prognosis for this group of children with a very complex and severe heart defect and 3/ to also describe side effects and risks in fetuses and mothers of the fetal procedure.

Gender Difference in NET Activation in Patients With Congenital Heart Disease and Heart Failure...

Congenital Heart DiseaseHeart Failure1 more

Neutrophil hyperactivation has detrimental effects on cardiac tissue after injuries, leading to fibrosis lesions and cardiac dysfunction. It is now well-established that women present with different clinical symptoms in cardiovascular disease compared to men. A cardioprotective effect in women has been suggested in some studies including patients with congenital heart disease (CHD) and heart failure. Our hypothesis is that estrogen protects the hearts of female patients aged 18-45 with CHD. There is no information available as to the involvement of neutrophils in heart failure in females compared to male patients, and therefore this study will provide important information for both the CHD and neutrophil biology fields comparing NET activation in women and men with severe CHD.

Microcirculation and Vascular Function After Fontan Surgery

Congenital Heart Disease

Fontan Surgery is done for children with only one working lower chamber of the heart called the 'Single Ventricle'. This surgery involves making connections between the two big veins that drain oxygen deficient blood to the heart and the lung artery directly. Fontan patients may develop long-term complications such as reduced heart function or oxygen levels, increased pressure in the veins, liver or kidney problems etc. The reasons for these complications are poorly understood. The small blood vessels in the body or 'microcirculation' are tiny (can be seen only by microscope) and they supply food and oxygen to the tissues. Very little is known about what happens to the microcirculation in adult Fontan survivors . In this study the investigator want to understand why these adult Fontan survivors develop complications by looking at their microcirculation and comparing them with healthy people and those who were operated for other congenital heart diseases. The study will be conducted in East Midlands Congenital Heart Centre, Glenfield Hospital. Leicester.

Molecular and Cellular Characterization of Cardiac Tissue in Postnatal Development

Congenital Heart DiseaseTetralogy of Fallot

The study team will use small pieces of human hearts which are removed as part of a required surgical procedure to study different objectives. One of the objective is how calcium ions pass through the membrane of heart cells in order to tell the heart cell how much force to contract with when the heart beats. Investigators will also study the proteins and RNA of these pieces to determine how the newborn heart cells control their force of contraction differently from adult heart cells. Investigators hypothesize that infant hearts have different regulation of calcium entry than adult hearts. The study team also wants to study combinations of 3D cardiac spheres with multiple environmental cues that can improve functional and metabolic maturation of Human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) and generate a more clinically relevant cell model.

Evaluating Pulse Oximetry Bias in Children With Darker Skin Pigmentation

Congenital Heart Disease in ChildrenCardiomyopathies

In this prospective study, the investigators will enroll 154 children with arterial lines to determine the accuracy of pulse oximeters in children with darker skin pigmentation. Studies in adults suggest pulse oximeters may overestimate the true level of oxygenation in the blood as measured directly by co-oximetry. However, pediatric data are relatively limited. This study, which is funded by the FDA through the Stanford-UCSF (University of California San Francisco) Clinical Excellence in Regulatory Science and Innovation (CERSI) Program, will determine if the error/bias is associated with skin pigmentation and whether the error falls outside FDA standards. The broader purpose of the study is to work toward eliminating health disparities.

" Evaluation of Safety and Efficacy of Empagliflozin and Sacubitril/Valsartan for CHF With Reduced...

Congenital Heart DiseaseHeart Failure1 more

The treatment of adult patients with congenital heart disease (ACHD) and heart failure (HF) represents a great challenge since, to date, there is no standardized guideline for this specific population. Although new treatments for HF have been proposed, such as Sodium-glucose Cotransporter-2 (SGLT2) Inhibitors and neprilisin and angiotensin receptor inhibitors, the benefit of these drugs in patients with HF associated with congenital heart disease in adults has not yet been demonstrated. For this reason, this study pretends to evaluate the efficacy of empagliflozin and sacubitril/valsartan in this population.

Online Support 4 CHD Kids & Caregivers

Congenital Heart Disease

This study will evaluate a virtual mental health parenting stepped-care intervention (I-InTERACT-North) to determine if the program works to improve positive parenting skills and child behaviour among families with children born with Congenital Heart Disease (CHD). Recruitment will target children ages 3-9 years old from SickKids. We will also evaluate the acceptability and feasibility of the program among children and families to inform future delivery and multi-site trials. Results will evaluate whether I-InTERACT-North can improve parenting and child behaviour in these families and inform future best clinical practices for this population.

Stress Response and Neurodevelopmental Outcome After Cardiac Surgery Utilizing CPB in Children:...

Congenital Heart Disease

The overall goal of this project is to determine the role of anesthetic management in children undergoing cardiac surgery utilizing CPB in the setting of fast tracking and early extubation. An ideal anesthetic technique would ensure abolishing or diminishing stress response as would be evident by the stress markers levels and the level of two cerebral injury biomarkers (S 100 B and NSE). This should translate to better immediate postoperative outcome and hopefully improve both the short and the long term neurodevelopmental outcome in these children. The project is prospective, randomized and blinded study. The first and second aim of the study should be conducted over 2 year period. Our long term aim will be concluded when these children reach the school age.
