New study aims to spot heart transplant rejection without a biopsy
NCT ID NCT06774365
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 683 heart transplant patients to see if advanced heart scans (CMR) and blood tests can detect antibody-mediated rejection, a common complication. Participants must be stable and at least one year post-transplant. The goal is to find non-invasive ways to diagnose rejection earlier and more accurately.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better, non-invasive ways to detect rejection in heart transplant patients, reducing the need for biopsies.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly improve outcomes. Results may not change current practices if imaging or biomarkers prove unreliable.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Clinically stable adult heart transplanted patients will be consecutively enrolled during the routinely outpatient evaluation in the participating centers after IRB approval. Heart Failure and Transplant Unit of IRCCS AOUBO will be the project leader and coordinate the overall study. The investigators plan a one year period for the enrollment and eight months for the follow-up. Patients will be treated and followed according to the routinary clinical practice of each participating center.
