Summary
ABO-incompatible (ABOi) heart transplantation in infants is safe and effective, showing outcomes comparable to ABO-compatible transplants. Exploiting infant immunologic immaturity offers new opportunities in pediatric transplantation.
Area of Science:
- Pediatric Cardiology
- Transplant Immunology
- Immunobiology
Background:
- Infants face high mortality while awaiting heart transplants.
- Infants have reduced risk of hyperacute antibody-mediated rejection due to immunologic immaturity.
Purpose of the Study:
- Review clinical results of ABO-incompatible (ABOi) heart transplantation.
- Summarize evolution of ABOi listing strategies.
- Present evidence of immune tolerance post-ABOi transplantation.
Main Methods:
- Review of clinical results in published reports of ABOi heart transplantation.
- Analysis of ABOi listing strategies.
- Evaluation of immune tolerance data.
Main Results:
- Comparable midterm and long-term outcomes (survival, complications) between ABOi and ABO-compatible (ABOc) heart transplant recipients.
- Confirmed reduced antibody production to donor antigens in ABOi recipients.
- Identified obstacles to widespread ABOi transplantation in some regions.
Conclusions:
- ABOi heart transplantation leverages infant immunologic immaturity for pediatric transplant recipients.
- Further research into transplant immunobiology in the young may reveal additional opportunities.
