Clinical Trials

Does your child have Down Syndrome? Did they have a complete atrioventricular septal defect (CAVSD) repair within the first year of their life? Researchers in this study are investigating how the
brain develops in children with Down Syndrome who have congenital heart disease. To participate, your child must be between 5 and 12 years old and have Down Syndrome. The study will enroll children who have congenital heart disease as well as children who do not have congenital heart disease. The study is taking place in locations in Delaware, Georgia, Indiana, Massachusetts, Michigan, Missouri, New York, Ohio, Pennsylvania, South Carolina, Texas, Utah, Washington, D.C., and Toronto, Canada

Do you have coronary heart disease or are you healthy and would like to participate in research? This study is comparing how well two types of magnetic resonance imaging (MRI) scanners can detect different types of heart diseases, such as coronary heart disease, heart failure, congenital heart disease, and heart valve disease. The new type of MRI scanner in this study uses less energy than a traditional scanner and may be suitable for people who have metal devices in their bodies. This study is located in Bethesda, Maryland.

Are you or your child at least 13 years old and have sickle cell disease? In this stidy, researchers are trying to find out if a new medication improves the success of a blood stem cell transplant. People 13 years old or older who are eligible for a blood stem cell transplant to treat sickle cell disease may be able to participate. Healthy family members over age 13 who are matched to transplant recipients are also needed to donate blood for the study. This study is taking place at the National Institutes of Health Clinical Center in Bethesda, Maryland.
