The investigator's primary goal is to quantitatively detect donor-specific DNA in plasma of organ transplant recipients. The investigator believe's that donor specific DNA can be isolated and quantified from transplant recipient serum. The investigator hypothesizes that the percent level of donor DNA circulating in recipient serum will reflect transplant rejection.

Primary Outcome Measures:
  • Percentage of Donor-Specific Cell-Free DNA in Plasma [ Time Frame: 1 to 5 years ] [ Designated as safety issue: No ]
    Assay and laboratory protocol development and optimization. To develop and optimize an assay and protocol to detect donor-specific cell free DNA from recipient plasma. This aim will be ongoing throughout the multicenter study and the lab process is unblinded.

Secondary Outcome Measures:
  • Number of Circulating Donor-Specific Cell Free DNA [ Time Frame: 2 to 3 years ] [ Designated as safety issue: No ]
    To determine the threshold of elevation of circulating donor specific cell free DNA (cfDNA) and develop an accurate predictive model for cardiac allograft rejection. Clinical and demographic factors as well as quantification of donor specific and total cfDNA will contribute to the predictive model. This phase of the lab process is blinded.

Other Outcome Measures:
  • Measure true positive and true negative Donor Specific Cell Free DNA [ Time Frame: 4 to 5 years ] [ Designated as safety issue: No ]
    To validate the threshold and predictive model to evaluate sensitivity and specificity of donor specific cell free DNA to detect donor injury on a cellular level. This phase of the lab process is blinded.

Study Population

Study population will include patients of any age who have undergone cardiac transplant or who are listed to undergo cardiac transplant. Pediatric and adult heart transplant patients will be recruited from six cardiac transplant sites: Children's Hospital of Wisconsin, Arkansas Children's Hospital, Emory University, Duke Children's Hospital and Health Center, Columbia University Medical Center, and Vanderbilt University. The multicenter study will recruit up to 1,000 subjects over five years; of those, approximately 480 will be new transplant subjects. The multicenter study will expand a pilot study already implemented at Children's Hospital of Wisconsin. Children's Hospital of Wisconsin/Medical College of Wisconsin will serve as Coordinating Center for the Multicenter phase.


Inclusion Criteria:

  • Any patient who is "listed" to undergo or has in the past undergone heart transplantation.

Exclusion Criteria:

  • Any patient who is not currently listed to undergo heart transplantation and has not previously received a heart transplant, or who is unable or unwilling to provide documented informed consent for self or through a legally authorized representative.
