PediMACS is the pediatric portion of INTERMACS. While INTERMACS has always included durable devices implanted in pediatric patients, PediMACS has been developed to focus on capturing data elements unique to pediatric patients. PediMACS evaluates special issues in the pediatric population receiving Mechanical Circulatory Support Device (MCSD) therapy, differences in devices available, and the particular pediatric population for whom this therapy may be most effective. Elizabeth Blume, M.D. from the Chilldren's Hospital Boston, is the PediMACS Chair.
