The accuracy of forced vital capacity for diagnosing restrictive allograft syndrome and mixed phenotype of chronic lung allograft dysfunction.

Lung transplantation has become an invaluable approach for the treatment of end-stage respiratory diseases. However, survival after lung transplant remains limited due to chronic lung allograft dysfunction (CLAD), a fibrotic process affecting the airway and/or parenchymal compartments of the lung graft leading to a significant and persistent deterioration in lung function [1, 2]. With our accelerating understanding of CLAD, it has become evident that CLAD is a heterogeneous process comprised of multiple patterns of physiological and radiological features, which have strong implications for post-CLAD survival [3].
