Description of intervention(s) / exposure
Brief name: XVIVO Heart Box/Preservation System.

The XVIVO Heart Box is a general-purpose donor-organ preservation/transport system. It is a non-dedicated system designed to support and maintain any donated organ (e.g., heart, kidney, liver) during transport from the donor to the receiving hospital where the organ will be transplanted into the recipient.

This system will provide technical support functions to keep the organ in as near-physiologic state as possible.

The XVIVO Heart Box/Preservation System consists of three separate devices:

- XVIVO Heart Box (re-usable)
- XVIVO Heart Disposable (single use)
- Supplemented XVIVO Heart Solution (single use)

The heart box is the device controlling the preservation system. The container, organ transport components include the 1) XVIVO Heart Box and 2) XVIVO Heart Disposable. A sterile disposable kit is placed into the heart box and tubes are fitted to the pump and clamp unit in the box. The connectors for gas, temperature and pressure sensors, integrated in the disposable kit, are connected to the box. The disposable reservoir kit is filled with perfusion solution from bags with the sterile heart solution, washed red blood cells and additives. The donor heart is attached to the heart cannula and submerged in the perfusion solution. The temperature of the perfusion solution, the CO2/O2 gas flow supplied to the perfusion solution and the pressure in the coronary arteries are controlled by the heart box during the transportation.

Donor Organ Preservation Solution consists of 1) XVIVO Heart Solution (XHS) and 2) XVIVO Heart Solution Supplement (XHSS). This is a sterile fluid used for hypothermic flushing, transport, and storage of donor organs (e.g., kidney, liver, heart, and pancreas) for transplant. The solution is intended to maintain organ viability until the organ can be implanted in the recipient. After application, this device cannot be reused.

The XVIVO Heart Box will be primed by the procuring surgeon and perfusionist from the transplant recipient hospital, in a controlled environment such as an operating room, pump room or operative prep room. The procuring surgeon will place the donor heart into the XVIVO Heart Box system. The Perfusionist will then travel with the donor heart inside the XVIVO Heart Box system from the donor hospital to the recipient hospital.

The XVIVO Heart Box will be utilised to preserve 36 donor hearts in total. In the initial phase of the trial, 12 donor hearts will be procured and transported with the NIHP method with less than 6 hours of anticipated ischemic time (standard NIHP). The remaining 24 donor hearts will be a projected ischemic time of 6-8 hours (extended NHIP).

Statistical methods / analysis
Data analysis will be performed by a trained statistician. To provide an overall estimate of treatment effect, data will be pooled across study centres. Distributions of continuous variables will be assessed for normality and reported (for each time point) as mean ± standard deviation (SD) for parametric data and median (interquartile range or minimum, maximum) for non-parametric data. Categorical variables will be reported using frequencies and percentages.
