New Methods to Preserve Hearts for Life-Saving Transplants
Discover groundbreaking techniques revolutionizing heart transplants and improving organ preservation for life-saving surgeries.
Introduction
Heart transplants are a critical lifeline for patients suffering from end-stage heart failure, yet the demand for viable organs far exceeds the supply. According to the American Heart Association, over 3,500 heart transplants are performed annually in the U.S., but thousands more remain on waiting lists. The need for innovative solutions has never been more urgent.
Enter new organ preservation techniques, pioneered by top university hospitals, that are transforming the landscape of heart transplants. By extending the viability of donated hearts and simplifying preservation methods, these advancements are expanding access to life-saving procedures for both adults and infants.
This article explores the latest breakthroughs in heart transplant preservation, their impact on patient outcomes, and what they mean for the future of organ donation.

The Challenge of Heart Transplants
The Waiting List Crisis
Thousands of patients remain on the heart transplant waiting list, with an average wait time of 6 months to over a year. Sadly, many die before receiving a suitable donor organ.
Limitations of Traditional Preservation
Traditionally, donor hearts are preserved using cold storage, which keeps the organ viable for only 4–6 hours. This limited window restricts the geographic range of donors and recipients, reducing the chances of successful transplants.

Breakthrough Techniques in Heart Preservation
Normothermic Perfusion
One of the most promising innovations is normothermic perfusion, a technique that keeps the donor heart warm and functioning outside the body. This method extends preservation time to over 12 hours and allows doctors to assess the heart’s condition before transplantation.
TransMedics’ Organ Care System
The Organ Care System (OCS) by TransMedics is a portable device that maintains the heart in a near-physiological state. It pumps oxygenated blood through the organ, mimicking its natural environment.
Hypothermic Machine Perfusion
This technique uses a machine to circulate a cold preservation solution through the heart, reducing cellular damage and extending viability. Hospitals like UCLA Health have successfully implemented this method for pediatric heart transplants.
Case Studies: Real-World Applications
Atrium Health’s Success Story
Atrium Health’s Sanger Heart & Vascular Institute has utilized the OCS to perform over 50 successful heart transplants, significantly reducing wait times and improving outcomes for patients.
UCLA Health’s Pediatric Breakthrough
UCLA Health pioneered the use of hypothermic machine perfusion for pediatric transplants, enabling the successful transplantation of hearts from donors as far as 1,500 miles away.
Duke University’s Research
Duke University researchers are exploring the use of stem cells to revive hearts that were previously deemed unsuitable for transplantation, potentially expanding the donor pool.
The Future of Heart Transplants
Expanding the Donor Pool
New preservation techniques allow doctors to consider hearts from donors after circulatory death (DCD), which were previously unsuitable for transplantation. This could increase the number of available organs by up to 30%.
Reducing Geographic Barriers
By extending preservation times, these methods enable hearts to be transported across greater distances, reducing regional disparities in organ availability.
Improving Patient Outcomes
Early results show that hearts preserved using these techniques have lower rates of rejection and better long-term functionality.
How Patients Can Prepare for a Heart Transplant
Understanding the Process
Patients should work closely with their healthcare team to understand the transplant process, from evaluation to post-surgery care.
Staying Healthy
Maintaining a healthy lifestyle, including a balanced diet and regular exercise, can improve a patient’s eligibility and recovery prospects.
Exploring New Technologies
Patients and families should stay informed about advancements like normothermic perfusion and discuss their availability with their doctors.
FAQ: Heart Transplants and Organ Preservation
1. What is normothermic perfusion?
Normothermic perfusion keeps the donor heart warm and functioning outside the body, extending preservation time and improving viability.
2. How does the Organ Care System work?
The OCS maintains the heart in a near-physiological state by circulating oxygenated blood through the organ, mimicking its natural environment.
3. Can hearts from donors after circulatory death be used?
Yes, new preservation techniques are making it possible to use hearts from DCD donors, potentially increasing the donor pool.
4. What are the benefits of hypothermic machine perfusion?
This technique reduces cellular damage and extends the viability of donor hearts, enabling longer transport times and better outcomes.
5. How can patients improve their chances of receiving a transplant?
Patients should stay healthy, work closely with their healthcare team, and stay informed about new technologies and advancements.
Conclusion
The advent of new heart preservation techniques is revolutionizing the field of heart transplants, offering hope to thousands of patients on waiting lists. From normothermic perfusion to the Organ Care System, these innovations are expanding access to life-saving procedures and improving patient outcomes.
For medical professionals, patients, and health enthusiasts, staying informed about these advancements is crucial. As research continues, the future of heart transplants looks brighter than ever.
