Background: Lung transplant remains the only viable treatment for certain patients with end-stage lung diseases. Such patients can become either single or double lung recipients. The 2 procedures are associated with specific risks and benefits. The aim of the study was to assess the survival of patients after lung transplant in a single center.
Methods: The retrospective study consists of 128 lung transplant recipients. Patients underwent transplant between 2004 and 2017 because of following diseases: chronic obstructive pulmonary disease (28.2%), cystic fibrosis (26.5%), and primary pulmonary hypertension (12.3%), including idiopathic pulmonary arterial hypertension and interstitial lung diseases (33%). Patients with idiopathic pulmonary arterial hypertension were not treated with postoperative extracorporeal membrane oxygenation as left heart conditioning.
Results: Regardless of underlying disease, 75% of DLT recipients and 51% of SLT recipients reached 5-year survival (P = .0066). A total of 87% of lung transplant recipients with cystic fibrosis reached 1-year survival. Among lung recipients with primary pulmonary hypertension who underwent DLT and SLT, 5-year survival was reached by 84% and 51%, respectively (P = .025). Among patients with chronic obstructive pulmonary disease, 82% of DLT recipients and 62% of SLT recipients reached 1-year survival (P = .22). Patients who received transplants because of primary pulmonary hypertension presented the worst short-term survival among all SLT recipients.
Conclusions: Patients with CF have the best overall survival among all lung transplant recipients. Double lung transplant provides statistically significantly better outcomes than single lung transplant. This observation is also present among recipients who underwent transplant because of primary pulmonary hypertension, as single lung transplant is not recommended among such patients in particular.

Objectives: To investigate through a meta-analysis of comparative studies the impact of donor type (brain death DBD vs circulatory death DCD) on the short- and long-term outcomes of lung transplantation(LTx).
Methods: Literature search (terms "lung transplantation" AND "donation after circulatory death") was performed up to July 2022 and studies comparing outcomes of LTx from DCD versus DBD were selected. Primary endpoints were early and long-term mortality.

In the Twilight of Evidence: Is Bypass Surgery Still on the Table for Cardiac Allograft Vasculopathy?
J Clin Med
December 2024
Department of Cardiology, University Hospital Zurich, 8091 Zurich, Switzerland.
Cardiac allograft vasculopathy (CAV) is a major prognosis-limiting factor in patients undergoing orthotopic heart transplantation (HT). Due to the diffuse involvement of the coronary tree, CAV lesions are often not amenable to percutaneous coronary intervention (PCI), leaving coronary artery bypass grafting (CABG) and retransplantation as primary revascularization options. : The latest guidelines from the International Society for Heart and Lung Transplantation (ISHLT) recognize CABG as a viable option but with a downgraded strength of recommendation.

Extracorporeal carbon dioxide removal (ECCOR) is an emerging technique designed to reduce carbon dioxide (CO) levels in venous blood while enabling lung-protective ventilation or alleviating the work of breathing. Unlike high-flow extracorporeal membrane oxygenation (ECMO), ECCOR operates at lower blood flows (0.4-1.

Thoracic malignancies (lung cancers and malignant pleural mesothelioma) are prevalent worldwide and are associated with high morbidity and mortality. Effective treatments are needed for patients with advanced disease. Cell therapies are a promising approach to the treatment of advanced cancers that make use of immune effector cells that have the ability to mediate antitumor immune responses.
