Insights
The demand for donor hearts exceeds supply, leading to the use of "expanded criteria" donor hearts. Research reviews current data and suggests strategies to increase the donor pool for heart transplantation.
Area of Science:
- Cardiology
- Transplantation Medicine
- Organ Donation
Background:
- Increasing disparity between donor heart supply and demand for transplantation.
- Liberalization of donor heart acceptance criteria over recent decades.
- Routine use of hearts from donors with specific conditions (e.g., LVH, cocaine use, CPR).
Purpose of the Study:
- Review recent data on the utilization of "expanded criteria" donor hearts.
- Propose methods to expand the donor heart pool.
- Discuss emerging tools and ethical considerations in donor heart acceptance.
Main Methods:
- Review of recent scientific literature and clinical data.
- Analysis of outcomes associated with expanded criteria donor hearts.
- Exploration of novel donor sources and acceptance strategies.
Main Results:
- Expanded criteria donor hearts are increasingly utilized, expanding the donor pool.
- Potential for increasing donor pool through hepatitis C donors and circulatory death determination.
- Emerging role of donor biomarkers and risk scores in decision-making.
Conclusions:
- Expanded criteria donor hearts are a viable option to address organ shortages.
- Further strategies are needed to increase donor pool, including novel sources.
- Ethical considerations regarding donor information sharing require careful deliberation.
Abstract:
The growing disparity between the supply of donor hearts for transplantation and the demand for such organs has led to liberalization of the criteria for donor heart acceptance over the past few decades. The upper age limit and size restrictions for donor heart acceptance continue to be revised and hearts are being routinely used from donors with left ventricular dysfunction, left ventricular hypertrophy (LVH), cocaine use, multiple medical co-morbidities and after cardiopulmonary resuscitation. This article reviews recent data for use of such "expanded criteria" donor hearts and suggests ways to further increase the donor pool, including use of hearts from donors with hepatitis C and after circulatory determination of death. Donor biomarkers and risk scores may eventually aid in heart acceptance decisions, while ethical issues surrounding information sharing with transplant recipients remain a topic of great debate.
