Brief Summary | The long-term goal of this research initiative is to develop a new valve replacement option for neonates, infants and young children. The central hypothesis is that transplantation of a freshly isolated heart valve will be associated with superior outcomes compared to currently available options, including preserved cadaver valves, bioprosthetic tissue valves, or mechanical valves. This new operation has been named "partial heart transplantation". The proposed study is a single-center, nonrandomized single arm pilot trial of "partial heart transplantation" in neonates, infants and young children who require semilunar heart valve replacement. This "first in man" trial seeks to determine whether valve replacement using partial heart transplant is feasible and safe. Primary aims are survival one year and five years following the procedure. The hypothesis is that, when compared to historical controls who have undergone homograft valve replacement, those undergoing partial heart transplantation will have equal or superior survival one year and five years following the procedure. Secondary aims are to assess growth and function of the transplanted valve. The hypothesis is that when compared to historical controls who have undergone conventional valve replacement, those undergoing partial heart transplantation will have valve growth that corresponds with somatic growth and superior valve function 1 year following the procedure. Up to five patients will be enrolled in this trial over three years. |

Intervention ICMJE | Procedure: Partial Heart Transplantation
The donor heart will be recovered and the new heart valve will be removed from this heart by the clinical team. The child will be scheduled for an emergent operation once the donor heart valve is deemed acceptable. The child will have general anesthesia during surgery. This is a state of unconsciousness, which is carefully controlled by the anesthesiologist with a mixture of very potent drugs, to prevent or lessen pain. The child will have a partial heart transplant using the donated heart valve to replace the dysfunctional heart valve. Expected hospital stay will range from weeks to months. The medical care after surgery is performed by the child's clinical team. This type of re-operation could similarly be required after a standard heart valve replacement.
