Active clinical trials for "Heart Diseases"

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.

The study is a nested case-control study and the purpose is to describe the status of key nutrients(eg.folic acid and vitamins) supplementation among pregnant women in Shanghai, to find out the association between the level of serum key nutrients during peri-conceptional period and the incidence of congenital heart defects (CHD) in newborn, and to provide better preconception care.

A study about accuracy of pulse oximeter with hypoxemic measurements (Blue sensor, Masimo, Irvine, CA, USA) in children with cyanotic congenital heart disease

Patients with hypoplastic left heart syndrome and other single right ventricle lesions who have undergone the Fontan procedure have a high risk of neurodevelopmental disorders that affect quality of life and adulthood employment. This study will leverage the ongoing National Heart, Lung, and Blood Institute (NHLBI)-funded Single Ventricle Reconstruction Study by using innovative graph measures of brain connectivity to elucidate how alterations of the "connectome" in children with critical congenital heart disease are associated with developmental disabilities and their associated clinical risk factors. Improved understanding of these interrelationships may facilitate development of targeted interventions to improve outcome in the soaring population of adult Fontan survivors.

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.

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 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.

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.

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
