Active clinical trials for "Heart Defects, Congenital"

The purpose of this study is to identify if circulating platelet cyclic adenosine monophosphate (cAMP) levels can be used as a biomarker of milrinone efficacy in children following cardiac surgery or undergoing heart transplant.

This study aims to explore the frequency and types of micronutrient deficiencies in a sample of UK children with CHD using standard and novel markers in blood. The study will also explore whether micronutrient deficiencies increase the risk of complications after heart surgery. This study will identify any nutrient deficiencies that need monitoring in clinical practice.

This study will evaluate if the introduction of a supported exercise programme can improve physical and psychological well-being for adults with congenital heart disease.

The study is to evaluate the effect of modified ultrafiltration on different components of Thromboelastography (TEG) in neonates undergoing cardiac surgery using cardiopulmonary bypass.

The goal of the Fontan Imaging Biomarkers (FIB) study is to identify the associations of blood and urine biomarkers to imaging parameters of ventricular mechanics.

The CHAPTER III Study (Congenital Heart Adolescents Participating in Transition Evaluation Research) is a cluster randomized controlled trial evaluating the impact of a nurse-led transition intervention in combination with usual care, versus usual care alone, on preparing adolescents with congenital heart disease (CHD) to successfully transition from pediatric to adult cardiology care. The Canadian Pediatric Society and American Academy of Pediatrics have recommended that transition interventions begin in early adolescence. Therefore, the investigators propose to conduct a nurse-led intervention that addresses the educational needs of 13-14 year olds.

All neonates with congenital heart disease undergoing stage one palliation (Norwood procedure, Damus-Kaye-Stansel procedure) at Texas Children's Hospital will be regularly monitored for B-type natriuretic peptide (BNP) and Troponin level before the surgical procedure, on arrival to the cardiac intensive care unit after their surgical procedure, every 6 hours during the first 24 hours of the post-operative period, followed by daily levels for the first week, and then weekly during patient's regular laboratory work up schedule. These cardiac biomarkers are linked to demographic, hemodynamic, respiratory, pharmacological data available via Sickbay.

Congenital heart defects (CHD) are the most common congenital malformations. Despite the progress made in the last decades in diagnosis and treatment, CHD continues to be associated with significant morbidity and mortality. Several studies have shown a reduction in the quality of life (QoL) of parents of children with CHD, which may affect children too. The main research aim is to assess and to understand the impact of a psychoeducational intervention in QoL of parents with newborns with CHD. We are including parents of inpatient newborns in Neonatal Intensive Care Unit (NICU) of UAG da Mulher e Criança - Centro Hospitalar Universitário de São João (CHUSJ) with the diagnosis of non-syndromic CHD, between March 2019 and February 2020. We also included parents of newborns born at CHUSJ with the diagnosis of non-syndromic CHD, not admited in NICU, between September 2019 and February 2020. The inclusion criteria are: I) parents of newborns (up to 28 days) with the diagnosis of non- syndromic CHD; II) newborns hospitalized in CHUSJ; III) parents aged ≥ 18 years. Parents of newborns with other important co-morbidities associated with CHD and those who do not have good understanding and expression in Portuguese will be excluded. Parents will be divided in 2 study groups: INTERVENTION group (I) and CONTROL group (C). Group I will receive a psychoeducational intervention in addition to the usual routines of the Service. Group C will receive the usual routines of the Service. The psychoeducational intervention, which consists of 2 sessions lasting 90 minutes each one, will be performed as soon as possible after inclusion in the study. Participants will be evaluated in three moments: M1 beginning of the study; M2 4 weeks after the intervention (I) or after enrollment (C) and M3 16 weeks after intervention/enrollment. The primary outcome will be parental QoL, which will be evaluated through the World Health Organization Quality of Life-Bref (WHOQOL-Bref). The family impact and the perception of positive contributions will be secondary outcomes. These outcome variables will be assessed by the Impact on Family Scale and the Positive Contributions Scale - Kansas Inventory of Parental Perceptions, respectively. A semi-structured interview will be performed after all quantitative data have been collected. The authors expect to find an increase of QoL and positive contributions and a decrease of family impact in the intervention group comparatively to the control group.

Cardiac surgery under extracorporeal circulation (ECC) in newborns with congenital heart disease causes significant morbidity and mortality. The perioperative period is a period of major vulnerability implicated in the appearance of these sequelae, and it is therefore essential to monitor brain function during ECC. The quality of cerebral oxygenation in the perioperative period is routinely monitored non-invasively by infra-red spectroscopy, which makes it possible to estimate cerebral tissue oximetry from a surface electrode (NIRS). The association between time spent outside the limits of cerebral self-regulation and the occurrence of perioperative encephalopathy is not known. The purpose of this study is to determine whether disturbances in brain self-regulation during the operative period are associated with the occurrence of postoperative encephalopathy in children operated on for congenital heart disease in the neonatal period. The main objective of the research is to determine the association between time spent outside individually determined cerebral self-regulation limits and the appearance of brain lesions suggestive of low brain output. Secondary objectives will investigate the association between time spent outside self-regulatory limits and the occurrence of postoperative encephalopathy defined by clinical and encephalographic criteria and will study factors predictive of the development of postoperative encephalopathy.

The overall objective of this project is to optimize the use of diagnostic methods and follow-up programs in infants with congenital heart defects (CHDs) in order to reduce death and complications
