control

OTHER

standard care in case collateral ventilation is observed (by Chartis) with 3 months physical activity tele coaching between 3 and 6 months post allocation.

Behavioral: physical activity tele coachingProcedure: Lung volume reduction surgery (LVRS)

Endobronchial valves

EXPERIMENTAL

Endobronchial valves in case collateral ventilation is absent (by Chartis) with 3 months physical activity tele coaching between 3 and 6 months post intervention.

Device: endobronchial valvesBehavioral: physical activity tele coachingProcedure: Lung volume reduction surgery (LVRS)

Interventions

A ambulatory diagnostic bronchoscopy under general anesthesia will evaluate the presence or absence of collateral ventilation . The targeted lobar airway is temporarily occluded by means of a balloon catheter, which blocks inspiratory flow but allows expiratory flow, in order to assess whether the air flow gradually declines to zero, meaning absence of collateral ventilation. Only in case collateral ventilation is excluded, a therapeutic bronchoscopy will be scheduled to insert the one-directional endobronchial valves in the targeted lobar airways. We will only perform a unilateral intervention during which we will treat one or maximal two lobes at one side.

Endobronchial valves

3 month physical activity tele coaching intervention consisting of a project tailored smartphone application in combination with a step counter providing direct feedback.

Endobronchial valvescontrol

Patients not eligible for endoscopic lung volume reduction (or non responders of this intervention) can be referred for surgical lung volume reduction. With this procedure, the most emphysematous parts of the lungs will be surgically removed.
