Filter by:The aim of the study is to assess the characteristics, incidence and predictors of load-independent right ventricle (RV) diastolic dysfunction in patients with congenital heart disease (CHD) and adverse RV loading conditions by acquiring pressure-volume loops and compare these results to a population of patients with exclusion of coronary artery disease and absence of any known disease affecting the RV.
Ventricular septal defects (VSD) are the most common cardiac congenital heart defect (about 1/3 of patients with congenital heart disease). VSD management is related to hemodynamics and anatomical localization and the occurrence of complications. Small perimembranous VSD without pulmonary hypertension and without significant left to right shunting are tolerated, whereas large VSD with pulmonary hypertension require early surgical management in the first months of life. The management uncertainties concern the medium-sized perimembranous VSD causing a significant left-right shunt but without pulmonary hypertension, which are of variable treatment (surgical correction, percutaneous treatment, medical or abstention). There are no recommendations or consensus on the preferred indication of a therapeutic attitude. The Pediatric and Congenital Cardiology Subsidiary, within the French Society of Cardiology, set up an observatory of perimembranous VSD with significant shunting, without pulmonary hypertension the objectives of this study are: - To study the incidence of cardiovascular events in perimembranous VSD and search for predictive anatomical markers of events. - To study the evolution of echocardiographic and functional data of patients having percutaneous or surgical closure compared to patient managed medically. This observatory will provide a better understanding of the therapeutic algorithm in the management of VSD with pulmonary overload without pulmonary hypertension.
The study looks to learn more about the helpfulness of web-based transition education and its effect on transition readiness and health service utilization in the adolescent and young adult congenital heart disease population.
To demonstrate the safety and effectiveness of the Edwards Alterra Adaptive Prestent in conjunction with the Edwards SAPIEN 3 Transcatheter Heart Valve (THV) System in subjects with a dysfunctional right ventricular outflow tract/pulmonary valve (RVOT/PV) who are indicated for treatment of pulmonary regurgitation (PR). Following completion of enrollment, subjects will be eligible for enrollment in the continued access phase of the trial.
The purpose of this study is to further evaluate the safety and effectiveness of the Harmony™ TPV system. The Pivotal/CAS phases of the study have transitioned into a post-approval study to confirm the long-term functionality of transcatheter implantation of the Medtronic Harmony TPV.
This study will explore new ways of using magnetic resonance imaging (MRI) to evaluate pediatric patients with cardiovascular disease,congenital heart disease in patients of all ages, fetuses undergoing clinically indicated MR imaging.
The primary aims of this study are to 1. Develop an automated method of quantitation of RV remodeling in terms of regional RV surface curvature and area strain and assess the feasibility, repeatability and accuracy in normal subjects and patients with repaired TOF, patients with PS The secondary study aims of this study are to 1. Compare the differences of RV remodeling in repaired TOF patients, PS patients with sex and age-matched controls 2, Assess the relationship of our proposed parameters to global RV function and exercise capacity in repaired TOF patients and PS patient
The study is a prospective, non-randomised, open label clinical study to assess the safety of the Bioabsorbable Pulmonary Valved (PV) conduit (PV-001) in subjects > 2 years and < 22 years of age, undergoing Right Ventricular Outflow Tract (RVOT) reconstruction. It is a first in man feasibility study which will include 10-12 patients in up to 6 sites in Europe. The primary objective of the study is to assess the survival rate of subjects at 6 months following implantation of the Bioabsorbable Pulmonary Valved Conduit (PV-001). Secondary objectives: 1. The survival rate of subjects at 12 months following implantation of the Bioabsorbable Pulmonary Valved Conduit (PV-001) 2. The percentage of conduit failure at 6 months and 12 months, where conduit failure includes the need for reintervention or reoperation. 3. The pressure gradient across the pulmonary valve will have an acceptable level at 12 months follow up. 4. The pulmonary regurgitation measured will not exceed a moderate grading at 12 months follow up. 5. To evaluate the usability of the Bioabsorbable Pulmonary Valved Conduit (PV-001) during the surgical procedure, using exploratory parameters Long term safety will be assessed up to 60 months post implantation.
The overall goal of this project is to determine the role of anesthetic management in children undergoing cardiac surgery utilizing CPB in the setting of fast tracking and early extubation. An ideal anesthetic technique would ensure abolishing or diminishing stress response as would be evident by the stress markers levels and the level of two cerebral injury biomarkers (S 100 B and NSE). This should translate to better immediate postoperative outcome and hopefully improve both the short and the long term neurodevelopmental outcome in these children. The project is prospective, randomized and blinded study. The first and second aim of the study should be conducted over 2 year period. Our long term aim will be concluded when these children reach the school age.
Neonates, children with single ventricle congenital heart disease, and those undergoing multiple complex cardiac surgeries are at high risk of increased perioperative blood loss, and blood product transfusions. In addition, some of these patients will present an increased risk of postoperative thromboembolic complications. For a long time, bleeding management has been based on the empiric administration of different blood products (e.g. platelet concentrates, cryoprecipitates, and/or activated factor VII), topical hemostatic agents, and surgical manipulation. Recently, the use of viscoelastic tests (e.g. thromboelastography (TEG) or thromboelastometry (ROTEM)) increased, and allowed a better assessment of perioperative coagulopathy, and a more 'rational' treatment of bleeding. While TEG and ROTEM record the viscoelastic properties of whole blood by measuring mechanical impedance and related changes during clot formation, T2MR, a miniaturized, magnetic resonance-based diagnostic platform, measures how water molecules react in the presence of magnetic fields to evaluate a broad range of hemostasis measurements. In this study, we will prospectively collect demographic data, surgical characteristics, the amount of perioperative bleeding and blood product transfusion, results of laboratory assays, and postoperative outcomes (30-day follow-up or until discharge), with the aim to assess our current practice, and develop an algorithm-based approach for the administration of targeted blood product and pro-coagulant therapies. Our goals are: the reduction of blood product utilization, the reduction of the incidence of massive bleeding and postoperative thrombosis.
