Filter by:Ebstein anomaly and tricuspid valve dysplasia (EA/TVD) are rare congenital tricuspid valve malformations that carry among the highest mortality of all congenital heart disease diagnosed in utero. Despite the high mortality associated with severe EA/TVD in the fetus, it has only been studied retrospectively. By prospectively enrolling a cohort across multiple centers, many questions may be answered in the perinatal period and beyond. The registry will allow us to understand perinatal and postnatal decision-making in this complex group of patients across centers.
The objective of this study is to determine the safety and feasibility of autologous mononuclear cells (MNS) collected from bone marrow (BM) and using an add-on intramyocardial delivery for individuals with Ebstein anomaly undergoing surgical intervention compared to the control group undergoing the same surgical procedure without cell delivery. This add-on procedure has the potential to foster a new strategy for individuals with congenital heart disease.This is an open-label study of autologous MNC derived from bone marrow with a 2-year follow-up to document 1) incidence and severity of adverse event and 2) monitor changes in cardiac structure and function.
Ebstein anomaly is a rare congenital heart disease. It encompasses abnormalities of the tricuspid valve, the right atrium and the right ventricle (RV). Currently, cardiac magnetic resonance imaging (MRI) is considered the method of choice for the assessment of RV volume and function. To evaluate the right heart function VentriPoint method was designed to assess the RV in a fraction of the time, resulting in better efficacy and lower costs. VentriPoint is approved for Tetralogy of Fallot patients as well as patients with systemic RV in d-transposition of the great arteries. This method uses 2 dimensional standard ultrasound views linked to a VentriPoint Medical Systems unit. After acquisition, the physician identifies anatomical landmarks with dots on a number of the 2D ultrasound views through the heart. With a sensor (magnetic tracking system: GPS) on the ultrasound probe we know where the 2D plane is in 3D space. In this way the precise anatomical landmark is located in 3D space. The aim of the present study is to assess the feasibility, reliability and accuracy of the echocardiographic knowledge-based 3D reconstruction method to measure RV volume and function in patients with Ebstein anomaly. The accuracy of the method will be assessed by comparison with measurements obtained by cardiac MRI. In addition to the right ventricle the investigators want to assess the left ventricular function in patients with Ebstein anomaly in this study. By using speckle tracking echocardiography the investigators would like to investigate on the left ventricular contractility, rotation and synchrony of the left ventricle together with the RV. Not seldom the left ventricle is neglected in a patient with Ebstein anomaly by impressive findings of the right ventricle. Changes in the myocardial left ventricular structure (non compaction) are also described and may have negative impact on the function. The investigators want to analyze 25-30 patients with Ebstein anomaly including children starting at 11 years of age.
This study will investigate Ebstein's anomaly, a congenital abnormality of the tricuspid valve of the heart and try to identify the genetic origins of the disease. Adults and children 2 years of age and older with Ebstein's anomaly and healthy volunteers may be eligible for this study. Participants undergo the following procedures: - Blood tests: Three tube of blood will be collected, with the total amount limited to about half a teaspon for each two pounds of body weight. - Saliva sample collection: A small amount of saliva is collected by spitting into a sterile container. - Oral (cheek) swab: Cells are collected from the mouth using a soft brush to swab the inside lining of the cheek. - Electrocardiogram: The electrical activity of the heart is recorded using electrodes placed on the chest. - Echocardiogram: Heart function is assessed using ultrasound.
