Brief Summary
Prospective, 2-arm, randomised (2:1), multicentre, open-label clinical trial in patients with severe emphysema. The intervention arm will be treated with Bronchoscopic lung volume reduction in severe emphysema using thermoablation.The interventional treatment (bronchoscopic lung volume reduction) is compared with the usual conservative standard therapy (GOLD guidelines).
