In mid\u2010 to late\u2010systole the ventricular septum contracted vigorously, forming a bend or sharp convexity toward the left ventricle, while motion of the posterolateral basal left ventricle was diminished and delayed. This finding was not encountered In 35 other patients with innocent systolic murmurs, or in 15 patients with mitral regurgitation of etiologies other than mitral valve prolapse. This abnormal pattern of left ventricular contraction on cross\u2010sectional echocardiography occurred with equal frequency In patients with holoaystollc and late\u2010systolic prolapse; it was seen more frequently In patients with severe prolapse than In those with mild to moderate prolapse.<\/jats:p>","DOI":"10.1002\/ccd.1810070106","type":"journal-article","created":{"date-parts":[[2007,3,1]],"date-time":"2007-03-01T01:12:11Z","timestamp":1172711531000},"page":"35-41","source":"Crossref","is-referenced-by-count":1,"title":["Cross\u2010sectional echocardiographic visualization of abnormal systolic motion of the left ventricle in mitral valve prolapse"],"prefix":"10.1002","volume":"7","author":[{"given":"Ivan A.","family":"D'Cruz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shirish","family":"Shah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leroy J.","family":"Hirsch","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto N.","family":"Goldbarg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,10,24]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.54.5.716"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(69)90029-0"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(70)90726-5"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.47.1.27"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.48.2.287"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.52.3.490"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.49.3.428"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.57.3.503"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.50.1.33"}],"container-title":["Catheterization and Cardiovascular Diagnosis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fccd.1810070106","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.1810070106","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,12]],"date-time":"2023-11-12T06:39:57Z","timestamp":1699771197000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.1810070106"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1981,1]]},"references-count":9,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1981,1]]}},"alternative-id":["10.1002\/ccd.1810070106"],"URL":"https:\/\/doi.org\/10.1002\/ccd.1810070106","archive":["Portico"],"relation":{},"ISSN":["0098-6569","1097-0304"],"issn-type":[{"value":"0098-6569","type":"print"},{"value":"1097-0304","type":"electronic"}],"subject":[],"published":{"date-parts":[[1981,1]]}}}
