The present study was designed to define the echocardiographic spectrum of mitral valve motion in a population of young individuals without clinical evidence of significant cardiac disease or hypertension. Echocardiograms were performed on 136 normal volunteers. Six subjects (4.4 per cent) had mitral valve prolapse. Eighteen subjects (13.2 per cent) had a lesser degree of posterior systolic motion of the mitral valve leaflets which was suggestive but not diagnostic of prolapse. Minor degrees of posterior systolic mitral valve otion may represent a variant of normal. Caution should be exercised in making the echocardiographic diagnosis of mitral prolapse until this question is settled.<\/jats:p>","DOI":"10.1002\/jcu.1870050406","type":"journal-article","created":{"date-parts":[[2007,2,27]],"date-time":"2007-02-27T23:08:37Z","timestamp":1172617717000},"page":"243-247","source":"Crossref","is-referenced-by-count":17,"title":["Echocardiographic spectrum of posterior systolic motion of the mitral valve in the general population"],"prefix":"10.1002","volume":"5","author":[{"given":"Antoine","family":"Bloch","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul A.","family":"Vignola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harriet","family":"Walker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alan D.","family":"Kaplan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip N.","family":"Chiotellis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert S.","family":"Lees","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gordon S.","family":"Myers","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,12]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.52.4.651"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(75)90028-4"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.43.4.503"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.49.3.428"},{"key":"e_1_2_1_6_2","first-page":"293","volume-title":"Clinical usefulness of echocardiography.
