Active clinical trials for "Heart Defects, Congenital"

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.

It is estimated that the incidence of congenital heart disease varies between 0.5 and 1% of live births, 5,000 new cases per year currently in France These are serious diseases that can be life-threatening to more or less short term. The advances in surgical techniques in recent years has improved the prognosis of these patients in the first months of life. The success of surgery is, among other things, conditioned by a support per complex operation, involving a multimodal intensive monitoring, and respiratory and hemodynamic support techniques. These elements of surveillance, NIRS (Near-infrared spectroscopy) allows measurement of non-invasive tissue saturation (rSO2) in cerebral and renal oxygen. The fundamental principle of NIRS based on an estimate of the percentage proportion of cerebral oxy-hemoglobin. A light source is emitted by NIRS and through body tissues to the brain where the light will be absorbed and refracted depending on the tissue composition in oxy-hemoglobin. Refracted light will be analyzed by NIRS which in turn using software will help to determine a percentage of oxyhemoglobin. Normal values of cerebral NIRS are between 50 and 80%.NIRS can be used according to this principle to estimate cerebral tissue oxygenation but also for other tissues such as the kidney. More than the figure, those are changes NIRS compared to a baseline that will alert us to the conditions of tissue oxygenation and allow us to identify hypoxia times. Changes in the value of the NIRS depends on 3 criteria: the tissue blood flow, the percentage of oxyhemoglobin and deoxyhemoglobin percentage.

Pulse oximetry screening of newborn infants increases early detection of critical congenital heart disease and minimises the risk of circulatory collapse before surgery. This study provides an update on the implementation of pulse oximetry screening in Turkey

Turner syndrome is a congenital complete or partial lack one of the female sex chromosomes affecting 1 of 2000 live born girls. The syndrome is characterized by an increased prevalence of ischemic heart disease, aortic dilation and dissection, hypertension, stroke and autoimmune diseases in general. Our study aim is: Using MRI to further characterize and find risk factors leading to aortic dilation. Using MRI to assess the degree of aortic distensibility. Using Computed tomography x-ray scanning of the heart and coronary arteries to characterize the prevalence and degree of ischemic heart disease and coronary anomalies. Using pressure sensitive ultrasound (applanation tonometry) to assess the degree of aortic stiffness when compared to controls using end points as Pulse Wave Velocity, Augmentation Index and Central Pulse Pressure.

The objective of the study is to investigate congenital disorders of glycosylation in congenital heart diseases without a clear molecular or genetic basis.

The purpose of this study is to determine whether electroacupuncture preconditioning would provide protection against myocardial Ischemic-Reperfusion injury and systemic inflammation in children undergoing CPB for repair of congenital heart defects.
