Beskrivelse
Inclusion Criteria:
- All ages of heart or lung transplant recipients
- Recipients of re-do heart or re-do lung transplants
Exclusion Criteria:
- Patients wait-listed for multiple organ transplantation (e.g. heart-kidney, heart-liver, heart and lung.)
- Unable or unwilling to return to Stanford for biopsy and follow-up procedures
- Followed by Palo Alto VA Hospital after transplant surgery (VA patients are transplanted at Stanford, but all subsequent clinical care is performed at VA hospitals)

Proportion of cell-free donor DNA to recipient DNA in the recipient's blood stream as a marker of rejection.
Tidsramme: The outcome measure is assessed for each patient up to 5 years post-transplant. Sampling timepoints include: Days 1, 2, 3, Weeks 1, 2, 4, 6, 8, 10, 12, Months 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 and quarterly through year 5

We will use high throughput next generation sequencing to monitor the proportion of cell-free donor DNA to recipient DNA in the recipient's blood stream as a marker of rejection.
