Strategies for Expanding Donors Pool in Heart Transplantation

Area of Science:

• Cardiology
• Transplantation Medicine
• Regenerative Medicine

Background:

• Heart transplantation is the gold standard for end-stage heart failure.
• Increased demand for donor hearts due to improved post-transplant outcomes.
• A significant gap exists between the number of heart transplant candidates and available donor organs.

Purpose of the Study:

• To review the current state of heart donor organ shortage.
• To discuss strategies employed to expand the donor pool.
• To highlight emerging technologies and future directions in addressing organ scarcity.

Main Methods:

• Review of existing literature on heart transplantation and organ donation.
• Analysis of trends in heart transplant demand and donor organ supply.
• Evaluation of novel technologies in organ preservation and potential future solutions.

Main Results:

• Despite expanded donor criteria (e.g., hepatitis C virus positive, older donors) and improved allocation systems, organ shortage persists.
• Emerging technologies like normothermic regional perfusion and ex-vivo heart perfusion show promise but do not fully bridge the demand-supply gap.
• Thousands of patients die annually awaiting a heart transplant due to critical organ scarcity.

Conclusions:

• Current strategies are insufficient to overcome the critical shortage of donor hearts.
• Advancements in regenerative medicine and xenotransplantation are crucial for future solutions.
• Addressing the heart donor organ shortage requires continuous innovation and exploration of new frontiers in transplantation.
