OCS™ Lung TOP Registry For Donor Lungs for Transplantation

This is an all-comers registry that will enroll: 1. Patients who receive OCS™ preserved double lung transplants from either standard criteria donors or donors initially deemed unacceptable; and 2. Patients who receive a single lung transplant from OCS™ preserved lung pairs from either standard criteria donors or donors initially deemed unacceptable; and 3. All donor lungs that were perfused on OCS Lung System. Enrolled patients will fall into one of the following three possible analysis categories: 1. TOP SCDL PAS Primary Analysis Population: will be comprised of recipients transplanted with SCDL primary analysis population eligible donor lungs preserved on the OCS™ Lung System. 2. TOP DLIDU Primary Analysis Population: Will be comprised of recipients transplanted with DLIDU primary analysis population eligible donor lungs preserved on the OCS™ Lung System. 3. All Other Enrolled Patients: will be comprised of all OCS Lung transplanted patients in the TOP Registry that do not meet any of the above analysis populations. Patient enrollment in the TOP Registry will continue until 266 eligible DLIDU Primary Analysis Population recipients have been enrolled.
