Their rotational variables were compared with 18 controls.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All the patients (19 boys and 16 girls; median age: 44.4 days; range: 13\u201084\u2009days) showed normal septal motion preoperatively; however, septal motion changed into flat septum or paradoxical septal motion after surgery. Left ventricular end\u2010diastolic internal dimension and fractional shortening significantly decreased after surgery (<jats:italic>P<\/jats:italic>\u2009=\u2009.001 and <jats:italic>P<\/jats:italic>\u2009=\u2009.000). Patients showed significant postoperative reduction of peak systolic apical rotation and maximal torsion (<jats:italic>P<\/jats:italic>\u2009=\u2009.010 and <jats:italic>P<\/jats:italic>\u2009=\u2009.000). Peak systolic basal rotation decreased after surgery but it was not significantly (<jats:italic>P<\/jats:italic>\u2009=\u2009.106).

Decreased rotation\/torsion variables may reflect postoperative changes of ventricular loading conditions. Because systolic strain was preserved, postoperative echocardiographic results should not be interpreted as abnormal or decreased ventricular function.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jcu.22650","type":"journal-article","created":{"date-parts":[[2018,10,31]],"date-time":"2018-10-31T04:24:39Z","timestamp":1540959879000},"page":"88-94","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Left ventricular rotation and torsion in neonates and infants younger than three months with symptomatic ventricular septal defect: Acute effects from open heart surgery"],"prefix":"10.1002","volume":"47","author":[{"given":"Jung Eun","family":"Kwon","sequence":"first","affiliation":[{"name":"Department of Pediatrics, School of Medicine Kyungpook National University, Division of Pediatric Cardiology, Kyungpook National University Children's Hospital  Daegu Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1631-574X","authenticated-orcid":false,"given":"Yeo Hyang","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, School of Medicine Kyungpook National University, Division of Pediatric Cardiology, Kyungpook National University Children's Hospital  Daegu Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,10,30]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(76)90152-1"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2009.10.057"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1510\/icvts.2008.201723"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(03)01328-6"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezt003"},{"key":"e_1_2_7_7_1","first-page":"143","article-title":"The myocardial performance index in children after surgical correction of congenital malformations with intracardiac shunt","volume":"65","author":"Zacharska\u2010Kokot E","year":"2007","journal-title":"Kardiol Pol"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.5114\/aoms.2010.14251"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8175.2011.01448.x"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8175.2009.01037.x"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajpheart.00104.2016"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/echo.12374"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951113000978"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jjcc.2012.12.016"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2005.02.082"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.4070\/kcj.2008.38.11.596"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2005.09.067"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2007.04.045"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.105.537639"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.4250\/jcu.2016.24.3.223"}],"container-title":["Journal of Clinical Ultrasound"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fjcu.22650","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jcu.22650","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,14]],"date-time":"2023-09-14T22:01:57Z","timestamp":1694728917000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jcu.22650"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,10,30]]},"references-count":19,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2019,2]]}},"alternative-id":["10.1002\/jcu.22650"],"URL":"https:\/\/doi.org\/10.1002\/jcu.22650","archive":["Portico"],"relation":{},"ISSN":["0091-2751","1097-0096"],"issn-type":[{"type":"print","value":"0091-2751"},{"type":"electronic","value":"1097-0096"}],"subject":[],"published":{"date-parts":[[2018,10,30]]},"assertion":[{"value":"2018-07-10","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-09-23","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-10-30","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
