Phase I Safety and Feasibility Study of Intracoronary Delivery of Autologous Bone Marrow Derived Mononuclear Cells


About this study

The objective of this study is to determine the safety and feasibility of autologous mononuclear cells (MNC) collected from bone marrow (BM) and intracoronary delivery for individuals with declining ventricle systemic pumps. This procedure has the potential to foster a new strategy for congenital heart patients. This is an open-label study of autologous MNC derived from bone marrow with a 2-year follow-up to document 1) related serious adverse events and 2) monitor changes in cardiac structure and function.
