Figure 2: Passive deflation flow-volume curves for Patient # 5 As part of the pulmonary function tests, passive deflation flowvolume curves were measured during the exhalation phase of a single occlusive breath. There is marked expiratory flow limitation demonstrated on both curves. Comparison of the flow-volume curves before and after surgical correction of Tetralogy of Fallot (TOF)- absent pulmonary valve syndrome (APVS) show increased airflow within the larger airways (within the arrows A and B) postoperatively but no changes in airflow within the small airways (represented beyond arrow B)
