Search for Noninvasive Markers of "Graft Injury" in Pediatric and Adult Patients With Congenital Heart Disease Undergoing Cardiac Transplantation

Not applicable Interventional IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT06784440

This study is testing a new blood test to see if it can help detect heart transplant rejection in patients with congenital heart disease without needing a more invasive procedure.

What this trial studies

This clinical trial aims to validate a new diagnostic method for detecting acute myocardial rejection in patients with congenital heart disease undergoing heart transplantation. The study will evaluate plasma levels of donor-derived cell-free DNA (Dd-cfDNA) in the recipient's blood and compare its effectiveness to the current gold standard, which is endomyocardial biopsy. Approximately 20 pediatric and adult patients will be enrolled, and blood samples will be collected during routine biopsies to analyze Dd-cfDNA levels. The goal is to determine if this noninvasive method can predict rejection with similar sensitivity as traditional biopsy methods.

Who should consider this trial

Good fit: Ideal candidates include pediatric and adult patients with congenital heart disease who are undergoing cardiac transplantation.

Not a fit: Patients who are not undergoing cardiac transplantation or those who cannot provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a less invasive and more accessible method for monitoring heart transplant rejection in patients with congenital heart disease.

How similar studies have performed: While the approach of using Dd-cfDNA is gaining interest, this specific application in congenital heart disease patients undergoing transplantation is relatively novel and has not been extensively tested in prior studies.
