Partial Heart Transplantation: Early Experience With Pediatric Heart Valve Replacements That Grow.

Abstract

Heart valve replacement in children is fraught with long-term morbidity and mortality rates, largely because conventional implants lack the capacity to grow with the child. Partial heart transplantation presents a potential solution by transplanting only specific segments of a donor heart, thereby providing a living and growing heart valve implant. This approach harnesses the full spectrum of cardiac tissues, which, when freshly procured and supported by immunosuppression, can integrate as functional and potentially growth-capable tissue. This state-of-the-art review discusses the history and development of partial heart transplantation, its indications, recent clinical experiences, regulation, and future directions.
