Lungs From Donors ≥70 Years of Age for Transplantation-Do Long-Term Outcomes Justify Their Use?

Donor shortages have led transplant centers to extend their criteria for lung donors. Accepting lung donors ≥70 years of age has previously shown good short-term outcomes; however, no mid- and long-term outcome data on these extended criteria donors has been published to date. In this study, all patients who underwent lung transplantation between 06/2010 and 12/2019 were included in the analysis, and the outcomes were compared between patients receiving organs from donors <70 years of age and patients transplanted with lungs from donors ≥70 years of age. Among the 1,168 lung-transplanted patients, 62 patients received lungs from donors ≥70 years of age. The recipient age of those receiving older organs was significantly higher, and they were more likely to suffer from obstructive lung disease. Older donors were exposed to significantly shorter periods of mechanical ventilation prior to donation, had higher Horowitz indices, and were less likely to have smoked. The postoperative time on mechanical ventilation, time on ICU, and total hospital stay were comparable. The overall survival as well as CLAD-free survival showed no differences between both groups in the follow-up period. Utilization of lungs from donors ≥70 years of age leads to excellent mid- and long-term results that are similar to organs from younger donors when the organs from older donors are carefully preselected.

Lung transplant and severe coronary artery disease: results from a single-centre experience.

OBJECTIVES: The management of severe coronary artery disease at the time of a lung transplant remains a challenge. We analysed the short- and long-term outcomes of lung transplant recipients with severe coronary artery disease. METHODS: Records of adult patients who received transplants at our institution between April 2010 and February 2021 were reviewed retrospectively. Severe coronary artery disease was defined as coronary stenosis ≥70% (main stem ≥50%) seen on the coronary angiographic scans performed before or at the time of listing. Patient characteristics, perioperative and long-term outcomes were compared between patients with and without severe coronary artery disease. RESULTS: Among 896 patients who received lung transplants who had undergone coronary angiography before the transplant, 77 (8.5%) had severe coronary artery disease; the remaining 819 (91.5%) did not. Patients with severe coronary artery disease were older (p < 0.0001), more often male (p < 0.0001) and received transplants more often for pulmonary fibrosis (p = 0.0007). The median (interquartile range) follow-up was 46 (20-76) months. At the Cox multivariable analysis, severe coronary artery disease was not associated with death. Patients with pretransplant percutaneous transluminal coronary angioplasty and patients with coronary artery bypass graft surgery concomitant to a transplant had survival equivalent to that of patients without severe coronary artery disease (p = 0.513; p = 0.556). CONCLUSIONS: Severe coronary artery disease was not associated with decreased survival after a lung transplant. Concomitant coronary artery bypass graft surgery and pretransplant percutaneous transluminal coronary angioplasty can be used for revascularization.
