New options for patients with COPD

Endobronchial valve therapy offers a new, non-surgical option for patients with COPD.

COPD is a debilitating pulmonary disease characterised by abnormal and permanent dilatation of airspace distal to the terminal bronchioles.

The resultant gradual destruction of the alveolar walls impairs gas exchange, leading to progressive gas trapping, and subsequent deterioration in pulmonary function, exercise capacity and quality of life.

In the early 1990s, the surgical technique of lung volume reduction was found to improve respiratory function, exercise tolerance, quality of life and survival in selected patients with heterogeneous, predominantly upper
