Transplanting heart valves from donors into patients who need them

Official title: Allogeneic Valve Transplantation

Run by Boston Children's Hospital · NCT06387446 · Data updated 2026-11-12

This study is testing if heart valves from donors can help kids and young adults who need valve replacements by providing a solution that grows with them and reduces the need for more surgeries later on.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include pediatric patients aged 30 days to less than 18 years and adult patients aged 18 to 50 years who require aortic, pulmonary, mitral, or tricuspid valve replacement.

Probably not a fit

Patients under 30 days old or those with irreversible multisystem organ failure or progressive systemic diseases may not benefit from this study.

What this trial studies

This study involves the transplantation of heart valves from organ donors into pediatric and young adult patients who require valve replacement. The focus is on patients whose heart valves may not grow with them, offering a potential solution that could reduce the need for multiple surgeries over their lifetime. The trial will evaluate the outcomes of these valve transplants, including any side effects experienced by the patients. The goal is to provide a durable valve option that can accommodate growth in younger patients.

Why it matters

Potential benefit: If successful, this approach could provide a long-lasting heart valve solution for children and young adults, minimizing the need for repeated surgeries.

How similar studies have gone: While this approach is innovative, similar studies involving valve transplantation have shown promise, suggesting potential for success.
