NCT05194514

Brief Summary

The Investigator's are doing this study to see which method of organ preservation leads to better outcomes for donated hearts. There are two methods of organ preservation. The first method is the use of cold storage. With this method, the donor heart is stored in preservation fluid within bags that are then placed on ice and transported in a cooler. This is the usual method for transporting donor hearts. This is also known as "standard of care." The second method is the use of the SherpaPak™ Cardiac Transport System. With this method, the donor heart is kept at a steady, consistent temperature throughout transportation. This method is not typically used for transporting donor hearts. The study will include up to 20 people in total.

Study Arms (2)

SherpaPak™ Cardiac Transport System

OTHER

When a matching donor heart from a non-local donor offer (from Northern California, Arizona, Nevada or farther geographies) becomes available the recipient will be assigned a subject identification number and randomized 1:1 to receive a heart transported using either standard of care cold storage or the SherpaPak™ Cardiac Transport System.

Device: SherpaPak™ Device

Other: Cold Storage

Interventions

The SherpaPak™ Cardiac Transport System has been developed to provide a safe, consistent method for cold ischemic storage of donor hearts for transplantation. This device is FDA approved.

Limitations and Caveats

There are several limitations to our study. First, the small sample size limits our ability to detect clinical differences between the groups. Second, our primary clinical end points were only followed out to 30-days warranting further randomized trials aimed at assessing the long-term effects on clinical outcomes. Third, cardiac samples have a high dynamic range of proteins due to the abundance of contractile machinery within cardiomyocytes.
