Filter by:This study is being done to determine the mechanism(s) contributing to the onset of symptoms (i.e. shortness of breath and/or palpitations) as well as changes in heart structure in patients with congenital heart disease (CHD)
Congenital heart disease (CHD) is the leading cause of birth defects, with an incidence of 0.8%. Among CHD, univentricular heart disease or "single ventricle" is rare and complex. As a result of the improved patient care over the last decades, the number of children and adults with single ventricle is increasing significantly. Today, the main challenge is to ensure an optimal follow-up of these new patients in order to improve their life expenctancy as well as their quality of life (QoL). Currently, echocardiography and cardiopulmonary exercice test (CPET) are central in management of patients with single ventricle as part of good clinical practice guidelines. Single ventricle volumes and function are very difficult to asses with conventional echocardiography because of their complex geometry. Indeed, single ventricle size and morphology vary depending on the patient characteristics and on the initial CHD (before surgical repair). That's why conventional 2D echocardiographic parameters are not reliable for single ventricle assessment. Magnetic resonance imaging (MRI) is more effective in assessing single ventricle volumes and function. Nevertheless, MRI is not universally available, is not practical in many situations, is expensive, and is a relative contraindication in patients with pacemakers. Over the past decade, the use of the 3D echocardiography has increased. This is an available tool that can assess ventricular function and volumes in few seconds. Recent studies shown a good correlation between 3D echocardiography and MRI for assessment of ventricular volumes and function in patient with CHD and especially in those with single ventricle. Moreover, according to some authors, CPET parameters are strongly correlated with risk of hospitalization, risk of death, physical activity and quality of life, especially in patients with single ventricle. To date, there is no study performed about the relationship between 3D echocardiography and CPET parameters in patients with single ventricle.
Retrospective prospective Multicentric clinical follow up of patients with severe tricuspid regurgitation after being treated with the TricValve® Transcatheter Bicaval Valves System.
Heart failure with preserved ejection fraction (HFpEF) is a common and growing condition with a poor prognosis but the pathophysiology and management are still being investigated. The PREFER-CMR project aims to evaluate and validate the application of novel 4D cardiac magnetic resonance flow dynamic methods to measure left ventricular pressures and validate these measurements with direct pressure measurement by coronary angiography. This is a prospective observational study of patients with HFpEF undergoing clinical evaluation with coronary angiography who will also undergo contemporaneous cardiac MRI. The primary outcome will be the level of agreement between the two methods using angiography as the reference method.
This study requires the consecutive enrollment of 60 patients following the first event of acute myocardial infarction, evaluating B-Cell Activating Factor (BAFF) and methylglyoxal (MGO) levels in the acute setting (pre-reperfusion) and 3 months after reperfusion.
Almost 1% of infants are born with Congenital Heart Disease (CHD), an umbrella term referring to a range of anomalies in the heart's structure that are present at birth. Owing to significant medical advances, it is now estimated that more than 90% of persons born with CHD will reach adulthood. Children with CHD and their families' mental health outcomes need for psychosocial care. This study will intend to improve the psychological functioning of children, adolescents with CHD and their parents. The research will comprise of two major studies. The sample of first study will be based on a Cohort (From April 2021 to October 2021) of children, adolescent and their parents. Participants will be assessed for their psychological functioning and health related quality of life using Strength and Difficulty Questionnaire, pedsQL 3.0 cardiac module , Parental Stress Index , and 36-Item Short Form Survey. It is hypothesized that parental psychological functioning will mediate the relationship between psychological functioning of children and adolescent with CHD and their health related quality of life. It is also hypothesized that emotional behavioral issues of children and adolescents will moderate the link between parental psychological functioning and their quality of life. Illness parameters and sociodemographic correlates will serve as covariates in the study. This study will provide a baseline for the second study that is expected to use a randomized control trial of an intervention program based on training workshops derived from CHIP for the reduction in parental distress, emotional behavioral problem and improvement in health related quality of life among children, adolescent with CHD and their parents. The pretest-posttest design will be used. The randomized control trial will be conducted as per Consort Guidelines. A sub sample will be selected from the initial study using purposive sampling. Intervention study will include a subsample of CHD population (60 children and adolescents each) and their parents using purposive sampling technique. The participants will be randomly assigned to experimental & control groups. Illness related and demographic parameters will be distributed equally in both groups for establishing control. The intervention will be administered to experimental group only, while control group will receive regular treatment. Results of Pretest and posttest measures will be statistically analyzed. The designed intervention program (using problem solving therapy, psycho-education and Parenting the child with CHD training) will lower the level of parental stress in parents and emotional behavioral issues in CHD population. It will further increase the level of health related quality of life among children and adolescent with CHD and their parents. The research will incorporate psychosocial care with CHD population along with their regular treatment and thus improve their future health related outcomes in Pakistan.
To determine the feasibility of 64Cu-DOTA-ECL1i, an investigational PET imaging drug, at the cellular level in the myocardium for individuals who have suffered a heart attack or who have other inflammatory heart disease.
Today, MRI is the gold standard for the precise assessment of left ventricular volume and function, but presents the drawback of having a long acquisition time and of generating motion artifacts, in particular respiratory artifacts, requiring repeated sequences in apnea to cover the whole cardiac volume. These apneas are difficult to achieve in patients with ischemic heart disease and may lead to degradation of the images, an increase in the duration of the examination by repeated acquisitions and therefore to diagnostic inaccuracies. Artificial intelligence, already used in practice in cardiac MRI for automatic segmentation of the heart chambers, improves radiological interpretation with rapid and precise measurements. Deep-learning, which is part of artificial intelligence, would allow the reconstruction of cine-MRI sequences in free breathing, in order to overcome the artifacts from respiratory motions, and the improvement of diagnostic performance while improving examination conditions for patients. Patients coming for a cardiac MRI for the assessment of ischemic heart disease will be eligible to the protocol. If the patient agrees to participate, a free-breathing cardiac cine-MRI sequence with Deep Learning based image reconstruction will be added to the usual protocol. No follow-up will be required in this study.
The investigators conducted this retrospective study in a large single center with an annual birth of more than 20,000 newborns, from January 1, 2018 to December 31, 2019, to confirm the applicability and accuracy of pulse oximetry (POX) combined cardio-auscultation to screen congenital heart disease for neonates.
Today, 50 % of cardiac patients do not participate in cardiac rehabilitation due difficulties in navigating and accessing rehabilitation activities. HeRTA is a partnership project involving Center for Clinical Research and Prevention (CCRP), Hvidovre Hospital, Rehabilitation Center Albertslund and Copenhagen (municipalities), the Danish Heart Association, and local sports associations. A patient advisory board participate throughout the project to ensure a continued focus on patient interests. The overall aim of HeRTA is to develop and test the feasibility of a new, sustainable model for rehabilitation supporting patients to take part in rehabilitation and promoting life-long activity for all patients with heart disease. To ensure equal access to rehabilitation some activities are open to all patients, while others are tailored specifically to patients with vulnerability. The project unfolds in three phases: Development (1. January 1. 2020 - 14. November 2021): Partners and patients co-create content and procedures; Feasibility (15. November 2021 - 31. July 2023): The feasibility of the model is tested, and promising components are identified; Long-term follow-up and implementation (1. August 2023 - 31. December 2025): Long term effects are investigated and promising components are tested in new settings. During the feasibility phase the investigators will examine whether the intervention activities are feasible, acceptable, and may have positive effects for patients with heart disease. The investigators use qualitative data on implementation and acceptability of intervention among partners and patients. An randomisered controlled trial (RCT) component will assess effects on patient participation rates, health, physical activity level, and life quality. Data is collected from practitioners and patients through focus groups, observations, field notes, questionnaires, and interviews. Results will point to: - innovative ways to organize integrated rehabilitation pathways. - approaches to ensuring rehabilitation targeted at patient needs.
