Pediatric heart transplantation: The past, the present, and the future

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Transplantation Medicine

Background:

• Heart transplantation (HTx) has evolved from early 20th-century origins to become a life-saving procedure for pediatric patients.
• The first pediatric orthotopic heart transplant occurred in 1967 for a neonate with Ebstein anomaly.
• Currently, around 500 pediatric HTx procedures are performed annually worldwide.

Purpose of the Study:

• To review the historical progression and current status of pediatric heart transplantation.
• To highlight key advancements contributing to improved patient survival and outcomes.
• To discuss future directions and innovations in the field of pediatric HTx.

Main Methods:

• Historical review of heart transplantation milestones.
• Analysis of current pediatric heart transplant statistics.
• Discussion of advancements in medical and surgical care, including immunosuppression and mechanical support.

Main Results:

• Pediatric heart transplant survival has dramatically improved, with outcomes now measured in decades.
• Significant reductions in waitlist mortality and post-transplant complications have been achieved.
• Key factors include advances in immunosuppression, critical care, specialized transplant teams, and mechanical circulatory support.

Conclusions:

• Pediatric heart transplantation has transitioned from experimental to a standard, highly successful therapy.
• Ongoing research focuses on developing novel intracorporeal ventricular assist devices (VADs) for pediatric use.
• Future advancements include expanding donor criteria and exploring xenotransplantation to address organ shortages.
