Active clinical trials for "Heart Defects, Congenital"

This study intends to establish an automatic system for screening on children with congenital heart disease, the system include the auscultation of cardiac murmur and the test of oxygen saturation, the data was analyzed based on the cloud computing.

The study to be performed aims to design and develope an automated Intelligent Decision Support System for fetal echocardiography that can significantly assist the obstetric physician in the improvement of detection of fetal congenital heart disease compared to the common standard of care.

Our study is about to follow adult congenital patients, known with systemic right ventricle (mostly correct transposition of the great arteries ou congenitally corrected transposition fo the great arteries) and systemic valve severe regurgitation which was treated with a Mitraclip device on this tricuspid valve. It's an observationnal study with a 2 years follow up with clinical (symptoms, complications, VO2 exercice test) echographic and MRI outcomes .

Advances in paediatric cardiology and cardiac surgery have enabled the survival of most patients born with congenital heart disease (CHD) into adulthood. Many CHD patients have undergone palliative or reparative surgery earlier in life. As patients survive into adulthood, they may need intervention or surgery for residual haemodynamic lesions. This is because they are at risk of arrhythmias secondary to structure heart disease and are susceptible to acquired heart disease. In these patients, pre-operative and post-operative evaluation of right ventricular (RV) structure (shape and volume) and function is an essential component of clinical management. Advances have been made in cardiac imaging so that accurate assessment of the right heart chamber in terms of its structure, function and physiology is possible. However, this technology has as yet never been applied in an effort to comprehensively assess RV structure, function and physiology. Cardiac Magnetic Resonance (CMR) will be used in this comprehensive assessment of structure and function. Thus, this research will allow development of a comprehensive integrated biomedical engineering (BME) R&D platform for in-depth study and clinical diagnosis of the RV structure-function relationship and physiology and its association with biomarker, and exercise capacity in CHD.

This is a retrospective study. The investigators shall review the angiography data of 1200 consecutive cardiac catheterizations of children and babies with CHD (Congenital Heart Disease) since 1998 till now. Coronary artery origin and course will be evaluated in relation to the morphologic cardiac anomalies. Coronary artery anomalies will be described and statistical analysis will be performed.

The National Institute of Cardiovascular Outcomes Research (NICOR) collects data and produces analysis to enable hospitals and healthcare improvement bodies to monitor and improve the quality of care and outcomes of cardiovascular patients. The Congenital Heart Disease audit collects data on all cardiac surgery and therapeutic cardiac catheterisations procedures used to treat patients with congenital and acquired heart disease. For acquired heart disease, the audit covers all arrhythmias & cardiomyopathies in patients less than 16 years old only. For congenital heart disease, the audit collects data on both children and adult patients. The audit covers all specialist centers in the UK and Republic of Ireland. The project aims to improve the quality of care for children and adults with congenital heart disease by providing national comparative analysis of procedure specific activity and outcomes of cardiac surgery and therapeutic cardiac catheterisation procedures. The audit also provides quality indicators for the antenatal detection of major congenital heart disease. The current dataset is available from here: http://www.ucl.ac.uk/nicor/audits/congenital/datasets

The purpose of this study is to evaluate the hemodynamic values of neonates that are healthy and those with various congenital heart diseases and sepsis by using echocardiography and USCOM.

A nationwide observational study. Children operated with single-ventricle palliation between January 1994 and December 2017 operated in Sweden will be included retrospectively. Patients born with a functionally single ventricle but not undergoing surgery will not be included. Data regarding preoperative clinical characteristics and operative details will be obtained by medical records review and from The Swedish Registry of Congenital Heart Disease (SWEDCON). Using unique personal identity numbers assigned to all residents of Sweden, data from SWEDCON will be linked with dates of death.

Children born with congenital heart problems face numerous physical, developmental, and social challenges. Complications in pregnancy have potential to impair brain development, leading a smaller brain volume and less mature brain even in babies born at full term. As the brain is less mature, it may be more susceptible to oxygen deprivation and other forms of brain injury. Urgent surgery is often required in the first few weeks of life to improve functioning of the heart, but this surgery also carries a risk of additional brain injuries. The aim of this study is to provide a better understanding of factors associated with the development of brain injury in neonates undergoing heart surgery in the first year or life. The short-term aim of this study is to provide data to help our team to develop advanced monitoring software that can be used to guide perfusion of the brain during surgery with a view to preventing surgery-related brain injury. The mid-term goal of the study is to identify risk factors associated with brain injury and inflammation around the time of surgery, through using MRI and taking blood samples. A longer term aim of this study is to be able to follow the children as they develop to see if any problems develop later in life. In this study, we will ask parents to complete two brief questionnaires when their infant reaches 2 years of age. Overall, this study aims to improve our understanding of the causes of brain injury in patients born with congenital heart problems. The data provided by this study will help us to develop new tools for monitoring brain perfusion during surgery.

The objective of this study is to research the relationship between maternal exposure to environmental factors and fetal congenital heart disease in a community-based case-control study.
