Non-invasive detection of heart transplant rejection in children

Non-invasive Detection of Acute Cell-mediated Graft Rejection in Pediatric Heart Transplant Recipients: the Role of Cardiovascular Magnetic Resonance

Observational IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT06795958

This study is testing if a new type of heart imaging can safely detect rejection in children who have had a heart transplant, instead of using more invasive methods.

What this trial studies

This study aims to evaluate the effectiveness of multiparametric cardiac magnetic resonance (CMR) imaging as a non-invasive method for detecting acute graft rejection in pediatric heart transplant recipients. Currently, acute rejection is diagnosed through invasive endomyocardial biopsy (EMB), which carries risks and limitations. By utilizing CMR, the study seeks to characterize myocardial structure and function, and compare textural features of parametric maps between cases of rejection and those without. The goal is to improve the diagnosis of acute rejection and enhance patient care.

Who should consider this trial

Good fit: Ideal candidates for this study are children and young adults who have undergone heart transplantation before the age of 18 and are scheduled for routine EMB surveillance.

Not a fit: Patients who are less than 3 months post-heart transplantation may not benefit from this study due to confounding factors from ischemia-reperfusion injury.

Why it matters

Potential benefit: If successful, this approach could provide a safer, non-invasive alternative for monitoring heart transplant rejection in pediatric patients.

How similar studies have performed: While few studies have explored the use of CMR in this context, the approach is relatively novel and has not been extensively tested in pediatric heart transplant recipients.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* children and young adults (transplanted when they were ≤ 18 years) who undergo an EMB for routine surveillance without contraindications to contrast-enhanced CMR

Exclusion Criteria:

* We also don't recruit recipients who were \< 3 months post-heart transplantation to reduce the possibility of confounding from ischemia-reperfusion injury that occurs with the heart transplant procedure
