This study is about collecting information on heart transplants using a special device called the OCS Heart System. This device helps keep the donor heart healthy before it's put into the patient. The study looks at how patients do after getting a heart that was kept with this system. It's called a registry because it's like a list where we keep track of patient outcomes. The study will follow patients for up to five years after their transplant to see how they are doing. This study doesn't have specific requirements for who can join or who can't, meaning any patient who gets a heart preserved with the OCS system can be part of it. There is no mention of any compensation or specific risks associated with participating.

• Study follows patients up to 5 years after transplant.
• No special requirements to join the study.
• Focus is on real-world performance of heart preservation device.
