Earlier analysis by a paediatrician concluded no abnormalities. However, the previously performed spirometry test may have clarified the diagnosis in an earlier stage.<\/jats:p>\n               <jats:p>Severe hypoventilation was seen during the exercise test with hypercapnia and hypoxaemia while hearing a stridor during exercise. Eventually, a circular subglottic stenosis was seen on a CT scan of the chest. No malignancy or granulomatosis with polyangiitis was seen in biopsy and pathologic examination. There was no history of trauma, intubation or infection. Therefore, the diagnosis idiopathic subglottic stenosis was established. Bronchoscopic balloon dilation followed several times, leading to full recovery.<\/jats:p>","DOI":"10.1136\/bcr-2021-242149","type":"journal-article","created":{"date-parts":[[2021,11,30]],"date-time":"2021-11-30T12:06:09Z","timestamp":1638273969000},"page":"e242149","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Idiopathic subglottic stenosis and the consequences in cardiopulmonary exercise testing"],"prefix":"10.1136","volume":"14","author":[{"given":"Rick","family":"Verjans","sequence":"first","affiliation":[{"name":"Sports Medicine, Isala Zwolle, Zwolle, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7275-0677","authenticated-orcid":false,"given":"Sietske","family":"van Berkel","sequence":"additional","affiliation":[{"name":"Sports Medicine, Isala Zwolle, Zwolle, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tom","family":"Brandon","sequence":"additional","affiliation":[{"name":"Sports Medicine, Isala Zwolle, Zwolle, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans","family":"Grotjohan","sequence":"additional","affiliation":[{"name":"Pulmonary Medicine, Isala Zwolle, Zwolle, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,11,30]]},"reference":[{"key":"2025082804445292000_14.11.e242149.1","first-page":"628","article-title":"Aerobic parameters of exercise as a function of body size during growth in children","volume":"56","author":"Cooper","year":"1984","journal-title":"J Appl Physiol Respir Environ Exerc Physiol"},{"key":"2025082804445292000_14.11.e242149.2","unstructured":"Wasserman K .
