Study Arms (2)
bilateral
ACTIVE COMPARATORTreatment arm B - incomplete bilateral treatment of in total two lobes (contralateral). The study will only use Intrabronchial Valves™
unilateral
ACTIVE COMPARATORTreatment arm A - unilateral treatment with complete closure of the worst lobe of the lungs
Interventions
In severe cases of COPD even optimum treatment involving bronchodilatation with drugs, physical training and possibly oxygen therapy is unable to influence exercise capacity and the perception of dyspnoea to a sufficient extent. Given the assumption that the elastic recoil of the small airways can be improved by a reduction in lung volume and pulmonary function overall by more ergonomic breathing mechanics and diaphragm function, various endoscopic procedures for lung volume reduction are available. Here one of the most advanced techniques is the implantation of intrabronchial valves. The one-way mechanism of this valve allows air to escape from the downstream lung segment without any influx of "new" air during inspiration
