The angle between the left pulmonary artery and main pulmonary artery was measured using echocardiography and computed tomography angiography (CTA). Furthermore, STI was used to record the global longitudinal strain of the four\u2010chamber view (GLS4), the global longitudinal strain of the two\u2010chamber view (GLS2), and the global longitudinal strain of the right ventricle (RVGLS).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The GLS4, GLS2, and RVGLS values in the TOF groups with different pulmonary artery branch angles were significantly lower than those in the control group. Furthermore, the GLS2 and RVGLS values were significantly lower for angles of 90\u2010100\u00b0 and &lt;90\u00b0 (vs &gt;100\u00b0). Multivariate linear regression analyses revealed that pulmonary regurgitation and the angle between the left and main pulmonary arteries were two important factors affecting RVGLS. The Bland\u2010Altman consistency test revealed good agreement regarding the pulmonary artery branch angles measured using echocardiography and CTA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In patients with TOF, the RVGLS was lower for acute left pulmonary artery angulation than for round and blunt left pulmonary artery angulation. The angle of the pulmonary artery branches was an important factor affecting RVGLS. Echocardiography can be used to measure the angle of the pulmonary artery branches, which provides valuable information for surgical correction of pulmonary artery morphology.<\/jats:p><\/jats:sec>","DOI":"10.1111\/echo.14948","type":"journal-article","created":{"date-parts":[[2020,12,4]],"date-time":"2020-12-04T04:49:06Z","timestamp":1607057346000},"page":"89-96","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Assessing right ventricular systolic function using ultrasonic speckle\u2010tracking imaging in repaired Tetralogy of Fallot with different pulmonary artery branch angles"],"prefix":"10.1111","volume":"38","author":[{"given":"Shuai","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Echocardiography Diagnosis Children\u2019s Hospital of Hebei Province Hebei Medical University Shijiazhuang China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9052-5876","authenticated-orcid":false,"given":"Xinjian","family":"He","sequence":"additional","affiliation":[{"name":"Department of Echocardiography Diagnosis Children\u2019s Hospital of Hebei Province Hebei Medical University Shijiazhuang China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Echocardiography Diagnosis Children\u2019s Hospital of Hebei Province Hebei Medical University Shijiazhuang China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanhui","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Echocardiography Diagnosis Children\u2019s Hospital of Hebei Province Hebei Medical University Shijiazhuang China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2740-9538","authenticated-orcid":false,"given":"Jiaoyang","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Echocardiography Diagnosis Children\u2019s Hospital of Hebei Province Hebei Medical University Shijiazhuang China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Echocardiography Diagnosis Children\u2019s Hospital of Hebei Province Hebei Medical University Shijiazhuang China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yun","family":"Cui","sequence":"additional","affiliation":[{"name":"Department of Echocardiography Diagnosis Children\u2019s Hospital of Hebei Province Hebei Medical University Shijiazhuang China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Di","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Echocardiography Diagnosis Children\u2019s Hospital of Hebei Province Hebei Medical University Shijiazhuang China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,12,3]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(02)01886-7"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(00)02714-8"},{"issue":"1","key":"e_1_2_8_4_1","first-page":"39","article-title":"Analysis of pulmonary artery morphological variability in Tetralogy of Fallot","volume":"44","author":"Zhang WM","year":"2017","journal-title":"Int Cardiovasc Dis"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/198108"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000077064.67790.5B"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000004426"},{"key":"e_1_2_8_8_1","first-page":"1347","article-title":"Assessment of ventricular function in adults with repaired Tetralogy of Fallot using myocardial deformation imaging","volume":"16","author":"Menting ME","year":"2015","journal-title":"Eur Heart J Cardiovasc Imaging"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2010.05.010"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2013.11.009"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1067\/mje.2002.116532"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/echo.12386"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/echo.13362"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1093\/icvts\/ivw179"},{"key":"e_1_2_8_15_1","first-page":"III14\u20109","article-title":"Long\u2010term vascular function after total repair of Tetralogy of Fallot.
