NCT06055556

Brief Summary

The purpose of this study is to determine if a partial heart transplantation in patients with congenital heart disease is safe and feasible. Participants will have a partial heart transplant involving surgical replacement of the pulmonary valve with the heart valve and supporting blood vessels from an organ donor. The procedure, tests, medications, and follow-up visits will all be done per standard of care. Medical data will be collected to look at outcomes after surgery.

Outcome Measures

Primary Outcomes (2)

  • Number of eligible patients who can be matched for transplant and the tissues needed procured

    A measure of feasibility.

    Day 1

  • To assess valve growth following partial heart transplantation.

    This will be determined by looking at valve growth compared to body growth over time based on post-operative imaging.

    Year 2

Secondary Outcomes (2)

  • To determine whether valve replacement(s) using partial heart transplantation is safe.

    Year 2

  • To assess valve function following partial heart transplantation.

    Year 2

Study Arms (1)

Partial Heart Transplantation

EXPERIMENTAL

Participants will receive a partial heart transplantation to replace the pulmonary valve with fresh donor graft(s). This is an investigational procedure. This means this procedure is not done as a routine treatment for patients with congenital heart defects. Partial heart transplantation involves surgical replacement of the semilunar heart valve with the heart valve and supporting blood vessels and tissue from an organ donor. No other parts of the heart are transplanted besides the heart valve, blood vessel, and tissue surrounding the valve.

Procedure: Partial Heart TransplantationOther: Freshly procured valve

Interventions

Partial heart transplantation involves surgical replacement of the semilunar heart valve with a fresh donor graft. The surgical procedure (homograft valve replacement) is common and standard of care. The investigational aspect of this is using a freshly procured valve rather than a cryopreserved, cadaveric one and also the use of limited immunosuppression to help maintain the freshly procured valve as "living tissue".

Partial Heart Transplantation

Fresh donor graft semilunar heart valve.
