Management of potential cardiac donors

Area of Science:

• Cardiology
• Transplantation Medicine
• Critical Care Medicine

Background:

• Heart transplantation (HTx) success has improved, but donor organ shortages persist.
• Brain death induces complex pathophysiological changes affecting multiple organs, particularly the heart.
• Effective donor management is vital for maximizing donor organ utility and improving post-transplant outcomes.

Purpose of the Study:

• To review the pathophysiological changes in brain-dead donors affecting cardiac allografts.
• To outline management strategies for optimizing cardiac donor organ condition.
• To highlight specific considerations for potential cardiac donors.

Main Methods:

• Review of current literature on brain death pathophysiology and donor management.
• Assessment of hemodynamic and endocrinological alterations in brain-dead individuals.
• Emphasis on diagnostic tools for cardiac donor evaluation.

Main Results:

• Brain death triggers significant hemodynamic instability and hormonal imbalances.
• Cardiac dysfunction, including reversible forms, is common in brain-dead donors.
• Coronary artery disease risk factors require careful assessment in potential cardiac donors.

Conclusions:

• Optimized management of brain-dead donors can improve cardiac allograft quality.
• Serial echocardiography and coronary assessments are essential for cardiac donor evaluation.
• Addressing donor-specific pathophysiological changes is key to enhancing HTx success rates.
