Outcomes AlloMap Registry

The Long-term Management and Outcomes of Heart Transplant Recipients With AlloMap Testing (OAR) is a research registry (database). The purpose of the registry is to observe short- and long-term clinical outcomes in heart transplant recipients who receive regular AlloMap testing as part of allograft rejection surveillance.

Utility of Donor-Derived Cell-Free DNA (dd-cfDNA) in Association with Gene Expression Profiling (D-OAR)

This trial will study a new biomarker, dd-cfDNA, which scientists propose is a marker for cellular injury caused by rejection. Participation in the AlloMap registry (listed above) is a prerequisite to participation in this study.
