A diagnosis of primary pulmonary hypertension was suspected on the basis of a negative extensive cardiorespiratory work-up with a systolic pulmonary artery pressure of 41-46 mmHg calculated from repeated measurement of the maximum velocity of tricuspid regurgitation jets at 2.8-3 m x s(-1) by continuous-wave Doppler echocardiography. However, a right heart catheterization with a high-fidelity transducer-tipped catheter revealed pulmonary artery pressures of 22\/8 mmHg at rest, which remained within normal limits at exercise. This case indicates a possible misleading overestimation of pulmonary artery pressures from Doppler echocardiographic studies of tricuspid regurgitation.<\/jats:p>","DOI":"10.1183\/09031936.98.12061476","type":"journal-article","created":{"date-parts":[[2002,11,1]],"date-time":"2002-11-01T23:29:18Z","timestamp":1036193358000},"page":"1476-1478","source":"Crossref","is-referenced-by-count":17,"title":["False-positive diagnosis of pulmonary hypertension by Doppler echocardiography"],"prefix":"10.1183","volume":"12","author":[{"given":"JL","family":"Vachiery","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Brimioulle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V","family":"Crasset","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R","family":"Naeije","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"81","published-online":{"date-parts":[[1998,12,1]]},"container-title":["European Respiratory Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1183\/09031936.98.12061476","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T07:13:06Z","timestamp":1740381186000},"score":1,"resource":{"primary":{"URL":"https:\/\/publications.ersnet.org\/lookup\/doi\/10.1183\/09031936.98.12061476"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,12,1]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[1998,12,1]]},"published-print":{"date-parts":[[1998,12,1]]}},"alternative-id":["10.1183\/09031936.98.12061476"],"URL":"https:\/\/doi.org\/10.1183\/09031936.98.12061476","relation":{},"ISSN":["0903-1936","1399-3003"],"issn-type":[{"type":"print","value":"0903-1936"},{"type":"electronic","value":"1399-3003"}],"subject":[],"published":{"date-parts":[[1998,12,1]]}}}
