Key result
Partial heart transplantation shows favorable short-term valve function, tissue growth, and low complications in early reports.
Why the study?
Partial heart transplantation is an emerging surgical strategy for complex congenital and acquired valvar lesions, but unresolved aspects of immunosuppression and long-term outcomes remain as evidence is limited to small observational cohorts and case reports.

Partial heart transplantation is an emerging surgical strategy for complex congenital and acquired valvar lesions that demonstrates favorable short-term valve function and growth capacity, though long-term outcomes and optimal immunosuppression remain to be established.
Partial heart transplantation (PHT) represents a novel surgical strategy that leverages donor cardiac tissue to address complex congenital and acquired valvar lesions while preserving growth capacity. This narrative review describes the conceptual framework and technical considerations of PHT and reports short-term outcomes across a spectrum of applications based on small observational cohorts and case reports. Early clinical results, predominantly from a single institution, demonstrate favorable valve function, promising growth, and few complications. We outline key elements of pre-transplant evaluation, donor selection, and surgical technique, and discuss post-transplant outcomes, immunosuppression management, long-term potential, and unresolved aspects of immunosuppression and long-term outcomes to inform best practices and guide broader adoption of this emerging therapy.

Sisson et al. (2026) conducted a review in Complex congenital and acquired valvar lesions. Partial heart transplantation (PHT) was evaluated on Valve function, growth, and short-term complications. Partial heart transplantation demonstrates favorable short-term valve function, promising growth capacity, and few complications in small observational cohorts and case reports.
