Filter by:This study aims to establish normal coronary artery pulse Doppler flow patterns and velocities using transoesophageal echocardiography (TEE) in patients with a variety of congenital heart disease. This will be accomplished by performing pre-operative and intra-operative TEEs on up to 250 patients undergoing surgery for congenital heart disease.
This clinical trial is being done to see if giving surfactant (Curosurf®) will decrease the number of days that infants will need a breathing tube, decrease the days in the critical care unit and decrease the number of days needed in the hospital. The primary hypothesis for this study is that there will be fewer days needed on mechanical ventilation and improved lung compliance and pulmonary gas exchange.
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.
Pediatric cardiac patients undergoing surgical anesthesia are at an increased risk of poor neurologic outcome (20-50%). Unattenuated anesthetic exposure and pain contributes to physiologic perturbations that may increase neurologic morbidity. Because of the often-large exposure to anesthetic agents in these cardiac children, at such a young age and the potential modifying anesthetic practice that could lead to improved neurodevelopmental outcomes and surgical recovery is paramount. Regional anesthesia such as thoracic epidurals provide effective analgesia and reduced intraoperative anesthetic needed but carry devastating sequelae neurological risks of epidural hematomas after anticoagulation during cardiopulmonary bypass (CPB). Recently, a newly described erector spinae plane block (ESPB) is superficial to neuraxial or vascular structures, providing opportunity to be placed with less risk for surgery requiring CPB. This block has been described as effective regional anesthesia for adult cardiac surgery.
Valved conduits used for the reconstruction of right-ventricular outflow tract are applied in the surgical repair of complex congenital heart disease(CHD) such as pulmonary atresia(PA), truncus arteriosus, severe tetralogy of Fallot(TOF) for their significant roles in reducing pulmonary valve regurgitation and preserving right ventricle function. With a rising cases of complex CHD and patients with pulmonary valve regurgitation in TOF repair, a further demand is underway for valved conduits. Meanwhile, common biological valved conduits applied in foreign countries are not approved in China yet, with high failure and reintervention, reducing the long-term survival. Our team manufactured a novel valved conduit with 0.1mm expanded polytetrafluoroethylene and gore-tex conduit. This ePTFE valved conduit played a satisfying role in anti-regurgitation and failure rate through in vitro fluid test and animal experiments. Besides, our team manufactured templates for the conduit and also simplified the suturing process so that the repeatability of suturing valved had been risen. Until now, over 70 cases have been implanted with this ePTFE valved conduit with positive early and mid-term follow-up results. Despite the progress which have been made, there still remain some problems to solve. First, systematic prospective randomized comparative study will be performed. Second, this is just a single-center study. Third, these patients should have longer follow-up time to evaluate the ePTFE conduit long-term effect. Finally, imaging data are blank for evaluating the function of the conduit and right ventricle. In this prospective comparative research, the new designed ePTFE valved conduit and bovine jugular vein valved conduits are conducted as a randomized controlled trail. Cardiac magnetic resonance imaging is used to precisely evaluate the anti-regurgitation effect of the valved conduit and the right ventricle function. Investigators can further access the application of this newly designed ePTFE valved conduit. Investigators aim to provide a self-manufactured, low failure rate valved conduit.
Problem: With the increased survival rate of children with congenital heart disease, other health problems, in addition to the clinic, have emerged, such as the risks of developmental delay to which these children are exposed. There is a need for low-cost intervention studies that seek to minimize these risks. Objective: To evaluate the effect of an early stimulation program using parents as vectors of intervention, on the neurodevelopment of children with CHD Methodology: Randomized clinical trial, conducted with 44 dyads of parents-babies with CH considered as medium and high risk for developmental delays according to the guidelines of the American Heart Association (2012). The study will consist of two groups G1 (Intervention) and G2 (controls). G1 parents will receive guidance for 6 weeks of stimulation activities and will be instructed to keep an online execution diary, direct with the researcher through videos, and messages via cell phone. G2 parents will receive the standard guidelines currently used in pediatric cardiology clinics. Children from both groups will be assessed at the beginning and end of the 6 weeks by the Bayley Baby and Toddler Development Scales (3rd Edition). A questionnaire on the applicability of the protocol will be administered to the parents of the intervention group Expected results: Better neuropsychomotor performance in children after applying the early stimulation protocol. Perspectives: Create a body of information that can serve as a basis for the formulation of policies for intervention and surveillance of the development of this population.
Babies can be born with heart problems and sometimes need a heart surgery to fix the heart problem. Heart surgery can cause swelling from the build-up of extra fluid. Swelling can make it harder for babies to breath and has to be treated with medicine called diuretics. Swelling is hard to measure in babies, so it can be hard to know how much diuretic they need to treat the swelling. The investigators are looking for a better way to measure swelling in babies who have had heart surgery. Ultrasound uses sound waves to take pictures of the inside of the body. Ultrasound is used to take pictures of babies before they are born and to take pictures of their heart after they are born. New ultrasound software has been made from a company called MuscleSound that can quickly measure the amount of swelling in adults, usually in less than 2 minutes. This software has not yet been used to measure swelling in kids. This study plans to learn more about swelling in babies and will try to measure swelling in babies before and after heart surgery with the new ultrasound software. The study will also make the same measurements in babies who do not have heart disease to compare to babies having heart surgery.
The overall aim is twofold: 1) to stretch the borderline regarding the present knowledge of clinical and economic cost-effectiveness of eHealth as an aid for facilitating and supporting self-management in families with long-term childhood illness, and 2) to develop a sustainable multidisciplinary research environment for advancing, evaluating, and implementing models of eHealth to promote self-management for children and their families. A number of clinical studies are planned for, covering different parts of paediatric healthcare. The concept of child-centred care is essential. Experienced researchers from care science, medicine, economics, technology, and social science will collaborate around common issues. Expertise on IT technology will analyse the preconditions for using IT; economic evaluations will be performed alongside clinical studies; and cultural and implementation perspectives will be used to analyse the challenges that arise from the changes in relations among children, family and professionals, which may occur as a result of the introduction of eHealth. Child health is not only important in itself. Investments in child health may also generate significant future gains, such as improved educational and labour market performance. Six complex, long-term and costly challenges in paediatric healthcare are planned for, involving eHealth technology such as interactive video consultation, pictures, on-line monitoring, and textual communication. The research follows an international framework for developing and evaluating complex interventions in healthcare. End-users (families) and relevant care providers (professionals in health and social care) will participate throughout the research process. The overall aim is certainly to analyse eHealth as an aid for facilitating and supporting self-management. However, the plan also includes the research issue whether eHealth at the same time improves the allocation of scarce health care- and societal resources.
This study aims to identify the molecular genetic causes of the variability in development of calcific aortic valve disease in bicuspid and tricuspid aortic valves and their associated aortic dilation.
The primary objective of this study is to collect real-world clinical performance data to assess the clinical outcomes of patients receiving heart transplants using donor hearts transported via the SherpaPak CTS System. These results will be compared to outcomes of retrospective patients whose hearts were transported with the previous standard method.
