Background: To date, no studies have evaluated which of the various available Doppler methods are most reliable in determining LVDP in a consecutive patient population with different cardiac diseases. Methods: LVDP was estimated by the following Doppler methods (M): (1) M1\u2014the peak mitral regurgitant flow velocity (peak MR), (2) M2\u2014the mitral regurgitant velocity at the time of aortic valve opening (MR<jats:sub>AVO<\/jats:sub>), (3) M3\u2014the aortic regurgitant end\u2010diastolic flow velocity (AR<jats:sub>ED<\/jats:sub>), (4) M4\u2014the ratio of the transmitral to mitral annular early diastolic velocity (E<jats:sub>TM<\/jats:sub>\/E<jats:sub>DTI<\/jats:sub>), (5) M5\u2014a transmitral flow velocity regression equation (Regr<jats:sub>TM<\/jats:sub>), and (6) M6\u2014the difference of pulmonary venous and transmitral A wave duration (<jats:styled-content>A<jats:sub>PV<\/jats:sub>\u2212 A<jats:sub>TM<\/jats:sub><\/jats:styled-content> duration). For M1\u2013M3, sphygmomanometric blood pressure was used to calculate LVDP. Results: In 101 patients, the regression coefficient, standard error of estimate, and mean difference with confidence limits between Doppler and catheter\u2010derived measurements were as follows: <jats:styled-content>M1 (n = 46): r = 0.81 (P &lt; 0.0001)<\/jats:styled-content>, <jats:styled-content>4.3 mmHg and 3.7 \u00b1 12.0 mmHg; M2 (n = 47): r = 0.79 (P &lt; 0.0001)<\/jats:styled-content>, <jats:styled-content>5.4 mmHg and 1.1 \u00b1 11.2 mmHg; M3 (n = 20): r = 0.64 (P = 0.002)<\/jats:styled-content>, <jats:styled-content>7.8 mmHg and 4.6 \u00b1 17.6 mmHg; M4 (n = 50): r = 0.62 (P &lt; 0.0001)<\/jats:styled-content>, <jats:styled-content>5.6 mmHg and 0 \u00b1 11.2 mmHg; M5 (n = 79): r = 0.24 (P = 0.03)<\/jats:styled-content>, <jats:styled-content>7.1 mmHg and \u22120.1 \u00b1 16.8 mmHg; and M6 (n = 79): r = 0.22 (P = 0.05)<\/jats:styled-content>, <jats:styled-content>7.3 mmHg and 0 \u00b1 14.4 mmHg<\/jats:styled-content>, respectively. Conclusions: The Doppler measurement of mitral regurgitant jets is most accurate method to estimate left ventricular filling pressure noninvasively.<\/jats:p>","DOI":"10.1046\/j.1540-8175.2002.00645.x","type":"journal-article","created":{"date-parts":[[2003,7,24]],"date-time":"2003-07-24T13:12:14Z","timestamp":1059052334000},"page":"645-653","source":"Crossref","is-referenced-by-count":5,"title":["Validation of Six Noninvasive Doppler Methods for the Assessment of Left Ventricular Filling Pressure"],"prefix":"10.1111","volume":"19","author":[{"given":"Nils","family":"Kucher","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markus","family":"Schwerzmann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ernst","family":"Lipp","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Eyer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernhard","family":"Meier","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Seiler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2003,7,24]]},"container-title":["Echocardiography"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1046%2Fj.1540-8175.2002.00645.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1046\/j.1540-8175.2002.00645.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,18]],"date-time":"2023-11-18T11:46:49Z","timestamp":1700308009000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1046\/j.1540-8175.2002.00645.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002,11]]},"references-count":0,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2002,11]]}},"alternative-id":["10.1046\/j.1540-8175.2002.00645.x"],"URL":"https:\/\/doi.org\/10.1046\/j.1540-8175.2002.00645.x","archive":["Portico"],"relation":{},"ISSN":["0742-2822","1540-8175"],"issn-type":[{"value":"0742-2822","type":"print"},{"value":"1540-8175","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002,11]]}}}
