Are you scheduled for a stem cell transplant with cord blood? This study will assess the safety and effectiveness of certain cord blood transplants. The study will help researchers learn the best methods for collecting, storing, and using cord blood in transplants. To participate in this study, you must have a disorder that compromises your body’s ability to make blood cells. This study is located in Bethesda, Maryland.

Would you like to donate blood for a study of stored red blood cells? This study is evaluating how blood donors affect the stability of stored red blood cells. After collecting a blood sample from a healthy donor, researchers treat the red blood cells with a B vitamin called biotin and then store the sample. After about 1 week, some of the cells are transfused back into the donor to check how many of the red blood cells are still healthy after storage. After a few more weeks, more of the stored cells are transfused and tested again. To participate, your blood must meet certain requirements and you must be healthy, 18 years old or older, and weigh at least 110 pounds. This study is located in Pittsburgh, Pennsylvania.

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 have cardiomyopathy that has led to moderate or severe mitral regurgitation? This study is exploring the best surgical technique to repair mitral regurgitation by comparing two procedures called undersizing mitral annuloplasty (UMA) and papillary muscle approximation (PMA). A UMA is a common procedure that involves implanting a prosthetic ring onto the mitral valve to stop the valve from leaking. A PMA is a newer technique in which a suture draws together the two muscles that connect the mitral valve to the heart muscle prior to performing UMA. To participate in this study, you must be 18 years old or older and have never had a mitral valve repair procedure. This study takes place in Atlanta, Georgia.
