Acute complication posttransplant: primary allograft dysfunction

Area of Science:

• Cardiology
• Transplantation Immunology
• Medical Research

Background:

• Heart transplantation is the optimal treatment for end-stage heart failure, enhancing survival and quality of life.
• Primary graft dysfunction (PGD) is the leading cause of early mortality and morbidity post-heart transplant, despite advancements.
• Rising PGD incidence may stem from improved recognition or evolving transplant practices, with donation after circulatory death organs posing additional risks.

Approach:

• This review synthesizes current knowledge on PGD pathophysiology, risk factors, and management strategies.
• It examines the role of organ preservation and transport in PGD prevention.
• Evidence for modifiable risk factors and current interventions for PGD is summarized.

Key Points:

• Understanding PGD pathophysiology is crucial for optimizing donor and recipient management.
• Donation after circulatory death (DCD) organ utilization may increase PGD risk.
• Advanced organ preservation techniques and transport systems show promise in PGD mitigation.

Conclusions:

• Further research, including international collaboration for deep phenotyping and advanced risk prediction models, is essential.
• Developing robust PGD risk prediction models can help reduce early mortality in heart transplant recipients.
• Improved management of PGD is critical for enhancing long-term outcomes in heart transplantation.
