We are doing this study to find out if Non-Ischemic Heart Preservation using an experimental technology called the XVIVO Heart Preservation System (the study technology) is a safe and effective way to preserve extended criteria donor hearts that can be transplanted into patients who need a donor heart. The study technology is designed to preserve donor hearts using a device with a temperature-controlled perfusion solution that flows through the heart during transport. We want to know if this can allow donor hearts to travel a greater distance to patients who are awaiting a transplant.
