Brief summary
The purpose of this research study is to perfect the technique of EVLP and learn about the safety of transplanting lungs that have been ventilated (attached to a breathing machine or ventilator to deliver oxygen) and perfused with a lung perfusion solution (Steen solution™, made by Vitrolife). This ventilation and perfusion will be done outside the body (ex-vivo) in a modified cardiopulmonary bypass circuit (the kind of device used routinely during most heart surgeries). The purpose of performing ex-vivo lung perfusion and ventilation (EVLP) is to learn how well the lungs work, and whether they are likely safe to transplant.
Interventions
DEVICESteen Solution™
This solution is a buffered dextran and albumin-containing extracellular perfusate with an optimal colloid osmotic pressure developed specifically for extra-corporeal perfusion of lungs. After EVLP, lungs will be cooled in the circuit to room temperature, then flushed with cold Perfadex™ and taken to UNC Hospitals (UNCH) where they will have an ex-vivo CT scan. Lungs determined suitable will be offered to consented patients at UNCH based on Lung Allocation Score. Lungs not considered for transplantation may be subjected to different experiments but are not to be a part of this research study. In summary, lungs with good and stable function during EVLP with Steen Solution™ will be transplanted into recipients as per current clinical practice.
OTHERConventional Lung Transplant
No experimental procedures will be carried out. Lungs from conventional brain-dead organ donors will be used for transplant.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 30 Day Mortality | 30 Days | The primary objective evaluated for this study is recipient mortality at 30 days post transplant. 30 day mortality is used as a standard research assessment to evaluate post transplant outcomes. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Day 7 Ventilator/ECMO Status | 7 Days Post Transplant. | 7 days ventilator or extra-corporeal membrane oxygenator (ECMO free are being evaluated as secondary objectives. |
| Recipient mortality at 12 months. | 12 months | Recipient mortality at 12 months post transplant is being evaluated as a secondary objective. |
| ICU Length of Stay | Time to Discharge. | The length of ICU stay is another standard research and clinical outcome assessment post transplant and has been selected as a secondary objective. |
| Primary Lung Graft Dysfunction (PGD) | 24 and 72 hours post transplant. | Primary Lung Graft Dysfunction (PGD) is an indicator for significant morbidity and mortality after lung transplantation. Grade 0: PaO2\*/FIO2\*\* \> 300 with normal chest radiograph; Grade 1: PaO2/FIO2 \> 300 with diffuse infiltrates on the chest radiograph; Grade 2: PaO2/FIO2 between 200 and 300; Grade 3: PaO2/FIO2 \< 200. \* partial pressure of oxygen in the arterial blood (PaO2) \*\* fraction of inspired oxygen inspired oxygen fraction (FIO2) |
