Clinical Trial Summary

The primary objective of this study is to collect real-world clinical performance data to assess the clinical outcomes of patients receiving heart transplants using donor hearts transported via the SherpaPak CTS System. These results will be compared to outcomes of retrospective patients whose hearts were transported with the previous standard method.

Description:

This study is a registry study collecting data both retrospectively from patients already transplanted and prospectively from consecutively enrolled patients for heart transplantation. The study is a chart review study. Ongoing eligible recipients will undergo heart transplantation according to standard practices at each participating institution. This study will be conducted at an estimated 25 institutions globally and will have about up to 3000 patients. Subjects will be followed from transplant through one-year post-transplantation (i.e., 24 hours post-transplant, discharge, 30-days, 1-year, 2-years, 3-years, 4-years, 5-years). GUARDIAN provides critical and contemporary data on patient outcomes, with additional insight into risk factors and patient-related indices. Both donor and recipient information along with procedural details (including transportation) will be collected to provide information for major discrete endpoints such as death, primary graft dysfunction, right ventricular dysfunction, CPB weaning, Inotrope use, CAV diagnosis, rejection, and survival. Information about re-hospitalizations and re-transplantations is vital to address the integrated endpoint of days alive out of hospital, which is particularly relevant for this patient population. In addition, the number of in-hospital days and ICU time is closely tracked as the major resource utilized, after the initial transplant.

Intervention

Device:
• SherpaPak Cardiac Transport System
The Paragonix SherpaPak Cardiac Transport System ("SherpaPak CTS") is an ultraportable hypothermic preservation and transport system intended for use with donor hearts. The device is a legally marketed, FDA cleared medical device in the United States and CE Marked medical device in the European Union. The SherpaPak CTS consists of multiple components: 1) outer transport shipper which contains within various non-ice based temperature controlled packaging elements, 2) an inner and outer hard shell assembly which provides a rigid barrier enclosure in which the heart is immersed and suspended in a cold storage solution cleared for use in storing and transporting donor hearts, 3) a data logger that monitors and displays the temperature of the cold storage solution in which the heart is stored during transport, and 4) four size heart connectors designed to accommodate various size aortic stem diameters by which donor hearts are attached.
