We are happy to present you A 10-Year Follow-up Study of Survival after Endobronchial Valve Placement for Emphysema recently published in American Journal of Respiratory and Critical Care Medicine! This is one of the first long term follow up studies of Endobronchial Valves in Emphysema.
There is no effective therapy for advanced emphysema at present. Hence, to find novel therapeutic methods is needed. In the past decade, the new technology of bronchoscopic lung volume reduction with endobronchial valves (EBV) has been applied to clinical. Concerns of the less invasive bronchoscopic techniques to treat emphysema to achieve the similar beneficial effects to LVRS have been developed. Bronchoscopic lung volume reduction with EBV are one-way blocking devices that stop entry of air into the most affected emphysematous zone during inspiration while allowing it to escape during expiration in order to induce lobar atelectasis.
There are published several randomized controlled trials suggesting the role of EBV in patients with severe emphysema. Some non-controlled studies also demonstrated clinical improvements in lung volumes, health status and exercise tolerance.
