Surgical or bronchoscopic lung volume reduction are the most efficient therapeutic approaches for reducing hyperinflation in selected patients with emphysema. We here report the case of a 69-year old woman with COPD (GOLD stage 3-D) referred for lung volume reduction. She complained of persistent disabling dyspnoea despite appropriate therapy. Chest imaging showed marked emphysema heterogeneity as well as severe hyperinflation of the right lower lobe. She was deemed to be a good candidate for bronchoscopic treatment with one-way endobronchial valves. In the absence of interlobar collateral ventilation, 2 endobronchial valves were placed in the right lower lobe under general anaesthesia. The improvement observed 1 and 3 months after the procedure was such that the patient no longer met the pulmonary function criteria for COPD. The benefit persisted after 3 years.<\/jats:p>","DOI":"10.3390\/medicina55030065","type":"journal-article","created":{"date-parts":[[2019,3,12]],"date-time":"2019-03-12T03:49:31Z","timestamp":1552362571000},"page":"65","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Patient with GOLD Stage 3 COPD \u00ab cured \u00bb by One-Way Endobronchial Valves"],"prefix":"10.3390","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3502-485X","authenticated-orcid":false,"given":"Eric","family":"Marchand","sequence":"first","affiliation":[{"name":"CHU-UCL-Namur, site Godinne, Universit\u00e9 catholique de Louvain, Department of Pneumology, Institut de recherche exp\u00e9rimentale et Clinique (IREC), Av Dr Therasse 1, Yvoir, BE 5530, Belgium"},{"name":"Laboratoire de Physiologie Respiratoire, URPhyM, NARILIS, Facult\u00e9 de M\u00e9decine, UNamur.
