Brief 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.

Condition or disease Intervention/treatment
Heart Diseases Heart Failure Heart Defects, Congenital Device: SherpaPak Cardiac Transport System

Detailed 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 500 patients. Subjects will be followed from transplant through one-year post-transplantation (i.e., 24 hours post-transplant, discharge, 30-days, and 1-year).

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 and Inotrope use.

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.

Group/Cohort Intervention/treatment
SherpaPak CTS Patients
Patients whose donor heart was transported with the SherpaPak CTS
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.

Other Name: SherpaPak CTS

Standard Transport Patients
Patients whose donor heart was transported with a method other than SherpaPak CTS in the past two years

Primary Outcome Measures :
  1. Number of Patients with Primary Graft Dysfunction [ Time Frame: one year ]
    Less than 40% LVEF by echocardiography or hemodynamics with RAP greater than 15 mm Hg, PCWP greater than 20 mm Hg, CI less thann 2 L/min/m^2, hypotension with MAP less than 70 mm Hg (lasting more than 1 hour)

  2. Number of Patients with Right Ventricular Dysfunction [ Time Frame: one year ]
    hemodynamics with RAP grater than 15mm Hg, PCWP less than 15 mm Hg, CI less than 2 L/min/m^2, TPG less than 15mm Hg/pulmonary artery systolic pressure less than 50 mmHg OR need for RVAD

  3. Length of ICU Stay [ Time Frame: one year ]
    Length of time patient admitted to the intensive care unit post transplant

  4. Length of Hospital Stay [ Time Frame: one year ]
    Length of time before patient is discharged from the hospital post transplant

Secondary Outcome Measures :
  1. Hospitalizations [ Time Frame: one year ]
    Number of related hospitalizations post transplant

  2. Quality of Recovery [ Time Frame: one year ]
    Karnofsky score of patients as they recover will be compared. 100 is the highest score and 0 is the lowest. Higher scores are better outcomes and lower scores are worse outcomes.

  3. Speed of Recovery [ Time Frame: one year ]
    How quickly patients achieve a higher Karnofsky score during recovery will be compared. 100 is the highest score and 0 is the lowest. Higher scores are better outcomes and lower scores are worse outcomes.
