Do you or your child have a platelet, bleeding, or white blood cell disorder?
This study is looking at people who have platelet or other blood disorders. The researchers will use a blood sample to look for problems with platelets and a possible genetic cause in the participant’s DNA or RNA. To participate in this study, you must be a child or adult who either is healthy or has a platelet disorder, coagulation disorder, or white blood cell disorder. This study is located in New York, New York.

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.

Is your child undergoing heart surgery for congenital heart disease?
This study aims to help researchers better understand the developing heart and what controls the strength of its beats by comparing it to adult hearts. Researchers will study small pieces of the heart that are removed as a normal part of surgery or repair for children with congenital heart disease. To participate in this study, your child must be undergoing cardiopulmonary bypass surgery and be 18 years old or younger. The study is located in Atlanta, Georgia.

Do you or your child have a heart defect that requires a procedure called extracardiac conduit–total cavopulmonary connection (EC-TCPC)? This study is evaluating the effectiveness of a new type of graft called a tissue-engineered vascular graft for EC-TPC. Participants of this study will have this procedure and several follow-up assessments with magnetic resonance imaging (MRI) to test the performance of the graft. This study takes place in Columbus, Ohio.
