Using speckle tracking echocardiography, we investigated whether the extent of pre\u2010<jats:styled-content style=\"fixed-case\">CRT SF<\/jats:styled-content> was associated with left ventricular (<jats:styled-content style=\"fixed-case\">LV<\/jats:styled-content>) functional recovery after <jats:styled-content style=\"fixed-case\">CRT<\/jats:styled-content> device implantation. Fifteen patients with left bundle branch block with a mean <jats:styled-content style=\"fixed-case\">LV<\/jats:styled-content> ejection fraction of 23\u00a0\u00b1\u00a09% were enrolled in this study. The extent of presystolic ventricular flash (<jats:styled-content style=\"fixed-case\">PSVF<\/jats:styled-content>), which was defined if there was a peak in the radial strain curve in the preejection period, was semiquantified by counting the number of <jats:styled-content style=\"fixed-case\">PSVF<\/jats:styled-content>\u2010positive segments. Patients underwent radial strain analysis before and between 3 and 6\u00a0months after <jats:styled-content style=\"fixed-case\">CRT<\/jats:styled-content>. After <jats:styled-content style=\"fixed-case\">CRT<\/jats:styled-content> device implantation, <jats:styled-content style=\"fixed-case\">LV<\/jats:styled-content> end\u2010diastolic and end\u2010systolic volumes were decreased, <jats:styled-content style=\"fixed-case\">LV<\/jats:styled-content> ejection fraction was increased, and <jats:styled-content style=\"fixed-case\">LV<\/jats:styled-content> filling time corrected by RR interval was increased. The number of <jats:styled-content style=\"fixed-case\">PSVF<\/jats:styled-content>\u2010positive segments at baseline showed a graded association with improvement in both <jats:styled-content style=\"fixed-case\">LV<\/jats:styled-content> ejection fraction and <jats:styled-content style=\"fixed-case\">LV<\/jats:styled-content> filling time. In conclusion, the finding that a larger number of <jats:styled-content style=\"fixed-case\">PSVF<\/jats:styled-content>\u2010positive segments before <jats:styled-content style=\"fixed-case\">CRT<\/jats:styled-content> predicted fair <jats:styled-content style=\"fixed-case\">LV<\/jats:styled-content> functional recovery after <jats:styled-content style=\"fixed-case\">CRT<\/jats:styled-content> suggests that <jats:styled-content style=\"fixed-case\">PSVF<\/jats:styled-content> may represent a substrate that is amenable to functional response to <jats:styled-content style=\"fixed-case\">CRT<\/jats:styled-content>.<\/jats:p>","DOI":"10.1111\/echo.12308","type":"journal-article","created":{"date-parts":[[2013,7,30]],"date-time":"2013-07-30T11:59:56Z","timestamp":1375185596000},"page":"149-154","source":"Crossref","is-referenced-by-count":1,"title":["Association between Presystolic Ventricular Flash and Left Ventricular Functional Recovery after Cardiac Resynchronization Therapy"],"prefix":"10.1111","volume":"31","author":[{"given":"Takahide","family":"Ito","sequence":"first","affiliation":[{"name":"Department of Cardiology Osaka Medical College Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shun","family":"Kizawa","sequence":"additional","affiliation":[{"name":"Department of Cardiology Osaka Medical College Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shimpei","family":"Nogi","sequence":"additional","affiliation":[{"name":"Department of Cardiology Osaka Medical College Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinsaku","family":"Shimamoto","sequence":"additional","affiliation":[{"name":"Department of Cardiology Osaka Medical College Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaori","family":"Yokoyama","sequence":"additional","affiliation":[{"name":"Department of Cardiology Osaka Medical College Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobukazu","family":"Ishizaka","sequence":"additional","affiliation":[{"name":"Department of Cardiology Osaka Medical College Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,7,30]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.49.5.876"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehn481"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1532\/HSF98.20091129"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/eur235"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.105.554006"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2005.10.040"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.107.750190"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2010.09.038"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1460-9592.2003.00003.x"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0894-7317(03)00335-3"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.105.571455"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2010.01.015"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCHEARTFAILURE.111.962704"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehp050"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.2007.00719.x"}],"container-title":["Echocardiography"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fecho.12308","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/echo.12308","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,2]],"date-time":"2023-10-02T13:00:17Z","timestamp":1696251617000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/echo.12308"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,7,30]]},"references-count":15,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2014,2]]}},"alternative-id":["10.1111\/echo.12308"],"URL":"https:\/\/doi.org\/10.1111\/echo.12308","archive":["Portico"],"relation":{},"ISSN":["0742-2822","1540-8175"],"issn-type":[{"value":"0742-2822","type":"print"},{"value":"1540-8175","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,7,30]]}}}
