FIGURE 2 Early onset of adjusted bronchiolitis obliterans syndrome (BOS) Grade 1 (black arrow) and BOS Grade 1 using the conventional method (gray arrow) in a patient with pulmonary vascular disease. FEV1, forced expiratory volume in 1 second; LgTX, lung transplantation. The Journal of Heart and Lung Transplantation , DOI: ( /S (03) )

FIGURE 3 Ventilation scintigraphy before and after unilateral (right) lung transplantation for primary pulmonary hypertension in a patient with bronchiolitis obliterans syndrome (BOS). (A and B) The ventilation before (screening) and 1 month after LTX was distributed equally in the right lung and in the left lung. After onset of BOS, the ventilation percentage of the graft decreased in time and the ventilation percentage of the native lung increased in time (C, 29 months after transplantation, and D, 52 months after transplantation). The Journal of Heart and Lung Transplantation , DOI: ( /S (03) )

FIGURE 4 Conventional bronchiolitis obliterans syndrome (BOS) grading vs adjusted grading, taking into account ventilation percentages in the native lung of 10%, 30%, and 50%, respectively. FEV1, forced expiratory volume in 1 second. The Journal of Heart and Lung Transplantation , DOI: ( /S (03) )
