This week we speak with congenital heart surgeon T. Konrad Rajab of Arkansas Children's Hospital about a recent report he co-authored on piglet experiments on partial heart transplantation. How did transplanted heart valves grow in comparison to standard homografts and how did the valvular function differ with time? Is there a minimum dose of immunosuppresion that can protect these valves and can this dose be lower than full heart transplantation immunosuppresion therapy? Is partial heart transplantation considered a potential life-long approach to valve replacement or mostly something used to allow for growth of valves during childhood? What do we know about the world's limited experience in humans of this approach? Dr. Rajab shares the answers this week in an exciting 'sci-fi' episode. The future is now.
