MRI to Predict Rejection and Failure in Transplant and Cardiomyopathy Patients
NCT03822442 · View on ClinicalTrials.gov ↗
Study Summary
Overall Research Strategy of this protocol is to refine and validate noninvasive CMR imaging sequences with invasive hemodynamic and pathology results to create a comprehensive, noninvasive, radiation-reduced regimen for pediatric cardiomyopathy and cardiac transplant assessment. We were the first to perform MR-guided cardiac catheterization in US children, and have accumulated the largest US experience, having performed over 75 procedures to date. Our unique experience puts us in strong position to leverage this technology to improve care of children with cardiomyopathy and transplant. Using an integrated approach, we will simultaneously (1) validate imaging measures of cardiac edema and fibrosis by correlating T1 and T2 map images with endomyocardial biopsy (EMB) results in Aim 1; (2) overlay T1, T2 map images into our x-ray system to display "hotspots" of T1 and T2 abnormalities to guide EMB in Aim 2; and (3) obtain radiation-free hemodynamic data in a highly vulnerable pediatric population by using CMR to guide catheter manipulation in the ICMR suite in Aim 3. Age and diagnosis-matched historical controls will be identified from the last 10 years at Children's National as a control population for specific purposes of comparing (1) EMB yield without image overlay and (2) Radiation exposure during X-ray guided right heart catheterization. Identical information will be obtained and stored in the same 45CFR compliant database. Historical controls will be identified from the cardiac catheterization database by searching for age and diagnosis. A waiver of consent will be applicable here, as it would be inconvenient, insensitive and not feasible to consent families who have already undergone treatment.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03822442
The ClinicalTrials.gov registry entry for NCT03822442 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 200 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Children's National Research Institute, which has 114 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Heart Failure appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03822442 reports 1 study location spanning 1 distinct geographic area — top geographies include District of Columbia. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
