The Natural History of Pre-Existing Donor Specific Antibody and Amnestic Responses after Heart Transplantation

Purpose Sensitized patients have prolonged wait times for heart transplant and often low-level donor specific antibodies (DSA) will be crossed when accepting a donor heart. The purpose of this study was to determine if positive low-level DSA at the time of transplant increase in strength post transplant and increase the risk of antibody mediated rejection (AMR).
