In this study we seek to test the hypothesis that safety and clinical outcomes after cardiac transplantation utilizing HCV NAT+ donor organs as currently performed are acceptable.
The purpose of this study is to evaluate if Non-Ischemic Heart Preservation (NIHP) of extended criteria donor hearts using the XVIVO Heart Preservation System (XHPS) is a safe and effective way to preserve and transport hearts for transplantation.
1. Cell-free DNA does not vary significantly as a function of the activity of immunologically quiescent cardiac transplant recipients, despite the metabolic demands of the transplanted organ. (The implication of the null result would be that no restrictions to patient activity, nor modification of cardiac rehabilitation prescription, would be necessary to maintain proper test characteristics of AlloSure testing). 2. In immunologically active cardiac transplant allografts, exercise prior to assay of donor-derived cell-free DNA can be used to increase the sensitivity of the AlloSure test. (The implication of this would be that the optimal time-frame for drawing an Allosure may actually be post-exercise, and that window will be characterized).
