Radiological and clinical outcomes of using Chartis (TM) to plan endobronchial valve treatment
One-way endobronchial valves (EBVs) have been shown to relieve symptoms of emphysema, particularly in patients without collateral ventilation (CV) between the target and adjacent lobes. In this study, we investigated the ability of the bronchoscopic Chartis (TM) Pulmonary Assessment System to predict treatment response by determining the presence of CV. 80 EBV patients underwent a pre-treatment Ch
