Current results with pediatric heart transplantation

Area of Science:

• Cardiology
• Pediatric Surgery
• Transplantation Medicine

Background:

• Cardiac transplantation is a vital treatment for pediatric end-stage heart failure and complex congenital heart defects.
• This study focuses on outcomes in children undergoing heart transplantation, a critical intervention for severe cardiac conditions.

Purpose of the Study:

• To evaluate the efficacy and outcomes of pediatric heart transplantation.
• To assess early and long-term survival rates and identify key factors influencing results in pediatric heart transplant recipients.

Main Methods:

• Analysis of 95 heart transplants performed in 89 children (aged 4 days to 18 years) since 1988.
• Detailed review of patient demographics, underlying cardiac conditions (congenital defects, cardiomyopathy), prior surgical history, and pre-transplant UNOS status.
• Evaluation of post-transplant recovery parameters including ventilation time, inotropic support, ICU stay, and hospitalization duration.

Main Results:

• Achieved 96% 30-day survival, with median post-transplant ventilation of 1 day and ICU stay of 4 days.
• Demonstrated 1-year actuarial survival of 79% and 5-year actuarial survival of 69%.
• Identified acute and chronic rejection as the primary cause of mortality.

Conclusions:

• Pediatric heart transplantation is feasible with excellent early survival, even in complex cases with prior surgeries.
• Postoperative recovery metrics are manageable, yielding acceptable long-term results.
• Graft rejection remains a significant challenge requiring ongoing management strategies.
