Transforming Cardiac Transplant Organ Preservation
VP.S ENCORE® is a heart transplant perfusion device designed to support longer donor heart preservation and expand what may be possible in transplant timing, access, and donor utilization.
Extending the Window for Donor Heart Viability
Cold storage forces transplant teams to work within a narrow preservation window. With roughly 4–6 hours to work with, viable donor hearts may go unused due to limited preservation time, transport constraints, donor blood requirements, and system complexity.
VP.S ENCORE® addresses these limitations using donor heart preservation technology that is designed to fit into transplant workflows while supporting longer preservation and greater transport flexibility.
VP.S ENCORE®: A Simpler Path to Donor Heart Preservation

Simple
Blood-free perfusate
Eliminates the need for donor blood, reducing compatibility constraints
Seamless integration
No specialized fluids, setup, or equipment

Portable
Intuitive compact design
Built for single-person handling and easy maneuverability
Extended battery life
Supports air travel over long distances without specialized transportation

Reliable
Double the preservation window
Preclinical studies suggest VP.S ENCORE® may extend organ viability up to eight hours
Built-in cold storage fallback
Helps protect the life-saving organ if perfusion is disrupted
Preclinical Research Signals
- Up to 24 hours of successful preservation in porcine models
- Adequate lactate levels supporting organ viability and fitness for use
- No edema observed across porcine, adult human, and pediatric hearts
“Children are an underserved population when it comes to innovation, adaptation of technology, and clinical trials. It is our duty to advocate for them and continue to advance the care in pediatric medicine.”
