Brief Summary
This study aims to develop and refine a microRNA (miR) biomarker panel that can be used to phenotype net immune state after heart transplantation using circulating miRs (associated with drug doses and levels). These miRs will be used to characterize the overall immune state in adult heart transplant patients and predict patients that will go on to develop infection and rejection. MicroRNAs (miRs) are small, non-coding RNA molecules that regulate gene expression and serve as molecular biomarkers found in the circulation.

Outcome Measures
Primary Outcomes (2)
Time-to-Event Analysis of Circulating microRNAs (miRs) Predicting Infection in Pediatric Heart Transplant Recipients
A time-to-event analysis will be performed to identify specific circulating microRNAs (miRs) that predict the risk of infection in heart transplant recipients. Infections are defined as any bacterial, viral, fungal, or opportunistic infection leading to: 1) hospitalization, 2) prescription of antimicrobial therapy, or 3) reduction in immunosuppression
up to 3 years post - transplant
Time-to-Event Analysis of Circulating microRNAs (miRs) Predicting Rejection in Pediatric Heart Transplant Recipients
A time-to-event analysis will be performed to identify specific circulating microRNAs (miRs) that predict the risk of rejection in heart transplant recipients. Rejection is defined as treated rejection based on 1) endomyocardial biopsy (EMB) pathology, 2) unexplained graft dysfunction, or 3) molecular testing; leading to treatment with pulse dose steroids, monoclonal antibodies, plasmapheresis, and/or intravenous immunoglobulin (IVIg). EMB Pathology: Acute Cellular Rejection (ACR) Grade ≥ 2R and/or Antibody-mediated Rejection (AMR) Grade ≥ pAMR1, per International Society for Heart and Lung Transplantation (ISHLT) grading systems. Graft Dysfunction: Left Ventricular Ejection Fraction (LVEF) decline ≥ 10% from baseline and \< 50% absolute LVEF by echocardiography. Molecular Testing: Presence of 2 of the following 3 criteria-presence of HLA-DSA, elevated donor-derived cell-free DNA (dd-cfDNA), or gene expression results from blood or EMB testing.

Eligibility Criteria
Patients ≥ 18 years of age from geographically and socioeconomically diverse regions of the U.S who have undergone orthotopic heart transplant (OHT) Patients will be screened for eligibility and enrolled within \~ 1 month after heart transplant
You may qualify if:
- Age ≥ 18 years at enrollment
- Receipt of orthotopic heart transplant (OHT) within the prior 1 month ± 2 weeks
- Planned follow-up at the transplant center for a minimum of one-year.
- Patient able and willing to comply with the study visit schedule, study procedures, and study requirements.
You may not qualify if:
- Recipient of a multi-organ transplant
- History of prior solid organ transplant before the index heart transplant
- Ongoing mechanical circulatory support or hemodynamic instability (e.g., inotrope or vasopressor therapy)
- Ongoing need for renal replacement therapy and/or dialysis
- Active infection requiring either a) hospitalization b) treatment with antimicrobial therapy or c) reduction in immunosuppression
- Active rejection being treated with intravenous medications or plasmapheresis
