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.

Effectiveness of CRD-4730 in Participants With Catecholaminergic Polymorphic Ventricular Tachycardia...

CPVT1Heart Defects3 more

This is a Phase 2, multicenter, double-blind, sponsor unblinded, placebo-controlled, single-dose clinical study of CRD-4730 to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of CRD-4730 when administered as single oral doses to participants with Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT). The study will have 2 cohorts in which participants with CPVT will participate in a 3-period, randomized 2-sequence study. Each participant will receive 2 different doses of CRD-4730 and 1 dose of matching placebo, with each study drug administered as a single dose.

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.

" 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.

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.

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.

European Prospective Registry on Anomalous Aortic Origin of the Coronary Arteries

Congenital Heart DiseaseCoronary Artery Anomaly8 more

Anomalous aortic origin of a coronary artery (AAOCA) is a group of rare congenital heart defects with various clinical presentations. The lifetime-risk of an individual living with AAOCA is unknown, and data from multicentre registries are urgently needed to adapt current recommendations and guide optimal patient management. The European Registry for AAOCA (EURO-AAOCA) aims to assess differences with regard to AAOCA management between centres.
