Risk factors affecting mortality in pediatric heart transplantation: A comprehensive review of pre- and...

Area of Science:

• Pediatric Cardiology
• Transplantation Medicine
• Immunology

Background:

• Pediatric heart transplantation (HT) has significantly improved survival for children with end-stage heart failure.
• Despite advancements, mortality post-transplant remains a concern due to various risk factors.
• Understanding these factors is vital for optimizing patient outcomes.

Purpose of the Study:

• To review and synthesize current literature on pre- and post-transplant variables influencing mortality in pediatric HT.
• To identify key donor, recipient, and environmental factors affecting survival.
• To provide a framework for recognizing high-risk profiles in pediatric HT recipients.

Main Methods:

• Comprehensive literature review of pre- and post-transplant variables in pediatric HT.
• Inclusion of relevant adult HT studies for comparative analysis.
• Synthesis of data to identify critical risk factors for mortality.

Main Results:

• Pre-transplant factors like repeated sternotomies, high pulmonary vascular resistance, and extreme BMI impact outcomes.
• Post-transplant challenges include infection, rejection, and cardiac allograft vasculopathy (CAV).
• Social determinants of health significantly influence survival rates.

Conclusions:

• Identifying pre- and post-transplant risk factors is essential for improving pediatric HT outcomes.
• A multifactorial approach considering medical and social elements is necessary.
• This review aids in risk stratification for better graft survival and long-term management.
