Active clinical trials for "Heart Diseases"

Heart murmurs are commonly discovered in young children during clinical encounters in general practice. Heart murmurs might signal a structural cardiac disease that need to be treated, such as atrial septal defect. Thus, children with heart murmurs are routinely referred to comprehensive cardiac examination at a paediatric hospital department featuring echocardiography ('gold standard'). However, the great majority of such murmurs are innocent or physiological; ie., they do not represent a cardiac disorder. The prevalence of such innocent murmurs during routine random auscultation is estimated at 30 %. It would be advantageous if patients with a heart disease to a greater extent could be identified at the general practitioners' office: Healthy children would not be exposed to comprehensive cardiac examination The burden on the family would subside. Scarce medical resources in highly specialized departments would be better allocated, to the benefit of patients with real heart disease. The primary aim of this study is to establish the predictive value of cardiac markers in children with heart murmurs. Secondary aims are a) To do a pilot study of pediatric cardiac ultrasound examination in general practice; b) To establish age-adjusted reference range for cardiac markers in children, and c) To explore aspects of cardiovascular physiology in children. The investigators will include a total of 500 children aged 4 weeks to 10 years who is consecutively referred to the Dept. of Paediatrics, Akershus University Hospital, for assessment of heart murmurs. All participants will be subjected to clinical examination, symptom assessment, pulse oximetry, blood sampling (for troponin T, proBNP and other biomarkers), ECG recording, and echocardiography. A randomized subgroup of children will also undergo echocardiography performed by a general practitioner who has not received formal training in pediatric cardiology. The value of possible predictors will be assessed through the construction of Receiver Operating Characteristics (ROC) curves, and calculation of negative predictive value.

This is a retrospective, record-based study of approximately 100 patients across up to 12 centers within the United States. All patients who have been treated with the AngioVac Venous Drainage Cannula and the Extracorporeal Circuit will be considered for study participation. Eligible subject must meet all of the inclusion criteria and none of the exclusion criteria to be considered enrolled in the study. The purpose of the study is to describe initial experience with the AngioVac Venous Drainage Cannula and the Extracorporeal Circuit.

Congenital heart diseases (CHD) are the firt cause of congenital malformations (8 for 1000 births). Since the 90's, great advances in prenatal diagnosis, pediatric cardiac surgery, intensive care, and cardiac catheterization have reduced morbidity and early mortality in this population. Prevalence of " GUCH ", grown-ups with congenital heart disease has thus been significantly increasing. Nowadays, quality of life (QoL) assessment of this population is in the foreground. Our team is a reference center in the management of patient with CHD, from the fetal period to adulthood. The investigators have been conducting a clinical research program on health related QoL in pediatric and congenital heart disease. The investigators thus demonstrated the link between cardiopulmonary fitness and QoL in children with CHD aged 8 to 18 years, the correlation between functional class and QoL in adults with CHD, and the impact of therapeutic education on QoL in children under anticoagulants. Currently, no controlled cross-sectional quality of life study assessment has been leaded in the youngest children with CHD. This present study therefore extends our work in younger children aged 5 to 7 years.

The purpose of this observational study is to evaluate the performance of the Berlin Heart EXCOR Active driving unit while being used with the approved EXCOR ventricular assist device system.

The main objective of the work is to evaluate, in the French health care system, the performance of early ultrasound screening for severe heart disease between 11 and 14SA in high-risk populations.

Prevalence of type 2 diabetes (T2D) is increasing worldwide over the last two decades; in these patients the rate of all-cause and cardiovascular (CV) mortality is several folds higher than in the general population, configuring a major public health problem. The clinical phenotype is the main determinant of such high mortality risk; however, a relevant role is played by the disease duration, with a significant interaction with metabolic control. However, for T2D the diagnosis does not correspond to the true onset of the disease, and a high lethality rate also in patients with recent onset of the disease cannot be excluded. Robust evidence supports this hypothesis, showing as in subjects with new-onset T2D, the mortality risk is superimposable, and even higher, than that observed in people with overt and long-term T2D. In this complex scenario, it would be desirable an early identification of high-risk patients, in which an accurate estimation of risk of complications, coupled with appropriate and timely interventions, might help in reducing the risk of encountering premature mortality. The present study was design to address this specific issue.

This work suggests a methodology to adapt the injected radionuclide activity to the level of attenuation of each patient. The investigators propose a dose reduction adapted to the patient's weight, with no significant degradation of the image quality, in order to improve patients and staff radioprotection, standardize the image quality for easier clinical interpretation, and lead to radiopharmaceutical saving in the context of myocardial perfusion Imaging.

Valvular heart diseases are significant problem in Polish population. Coexistence of coronary artery disease in patients with VHD increases the risk of death and affects further therapeutic strategy. The aim of the study is analysis the epidemiology and the long-term prognosis among patients with VHD.

The primary technical endpoint was the diagnostic performance of the QFR against the FFR. The primary clinical endpoint was target vessel failure (TVF) between two groups distributed by a QFR cut-off value of 0.8

The Fontan procedure has revolutionized the treatment of patients born with a congenital univentricular heart defect. However, over time, it is associated with severe lymphatic complications such as plastic bronchitis, protein-losing enteropathy (PLE) and peripheral edema. The hypothesis is that patients with a univentricular circulation have a changed morphology which may be associated with both the degree of lymphatic complications and their physical capacity. The morphology will be described using T2-weighted non-contrast MRI.
