Heart-Lung Transplantation: The simultaneous, or near simultaneous, transference of heart and lungs from one human or animal to another.Lung Transplantation: The transference of either one or both of the lungs from one human or animal to another.Bronchiolitis Obliterans: Inflammation of the BRONCHIOLES leading to an obstructive lung disease. Bronchioles are characterized by fibrous granulation tissue with bronchial exudates in the lumens. Clinical features include a nonproductive cough and DYSPNEA.Lung: Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.Liver Transplantation: The transference of a part of or an entire liver from one human or animal to another.Transplantation, Homologous: Transplantation between individuals of the same species. Usually refers to genetically disparate individuals in contradistinction to isogeneic transplantation for genetically identical individuals.Primary Graft Dysfunction: A form of ischemia-reperfusion injury occurring in the early period following transplantation. Significant pathophysiological changes in MITOCHONDRIA are the main cause of the dysfunction. It is most often seen in the transplanted lung, liver, or kidney and can lead to GRAFT REJECTION.Heart: The hollow, muscular organ that maintains the circulation of the blood.Graft Rejection: An immune response with both cellular and humoral components, directed against an allogeneic transplant, whose tissue antigens are not compatible with those of the recipient.Heart Transplantation: The transference of a heart from one human or animal to another.Kidney Transplantation: The transference of a kidney from one human or animal to another.Lung Diseases: Pathological processes involving any part of the LUNG.Bone Marrow Transplantation: The transference of BONE MARROW from one human or animal to another for a variety of purposes including HEMATOPOIETIC STEM CELL TRANSPLANTATION or MESENCHYMAL STEM CELL TRANSPLANTATION.Hematopoietic Stem Cell Transplantation: Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.Graft Survival: The survival of a graft in a host, the factors responsible for the survival and the changes occurring within the graft during growth in the host.Tissue Donors: Individuals supplying living tissue, organs, cells, blood or blood components for transfer or transplantation to histocompatible recipients.Transplantation, Autologous: Transplantation of an individual's own tissue from one site to another site.Heart Rate: The number of times the HEART VENTRICLES contract per unit of time, usually per minute.
