In her subsequent pregnancy, an initial measurement of 47\u2005mm raised concern. Expert review highlighted the challenges of accurately measuring asymmetric neo-aortas post-ASO and confirmed that the neo-aorta was stable (43\u2005mm). The pregnancy continued without complications under beta-blocker therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>No neo-aortic dissections have been reported after ASO, and progression above 2\u2005mm was reported only in a few (2\/131). Preconception evaluation, standardized measurement techniques, and trimester-based surveillance are essential. Mode of delivery should be individualized; caesarean delivery may be reasonable when dilation exceeds 45\u2005mm.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1753495x261484223","type":"journal-article","created":{"date-parts":[[2026,9,15]],"date-time":"2026-09-15T04:22:57Z","timestamp":1789446177000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Neo-Aortic Root Dilation in Pregnancy After Arterial Switch for Complete Transposition of the Great Arteries"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-1498-9132","authenticated-orcid":false,"given":"Ariane","family":"H\u00e9bert M\u00e9tellus","sequence":"first","affiliation":[{"name":"Universit\u00e9 de Sherbrooke"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9126-1075","authenticated-orcid":false,"given":"Fran\u00e7ois-Pierre","family":"Mongeon","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Montr\u00e9al"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2231-396X","authenticated-orcid":false,"given":"Doan Hoa","family":"Do","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Sherbrooke"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-5900-2741","authenticated-orcid":false,"given":"\u00c9velyne","family":"Ra\u00eeche","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Sherbrooke"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-3571-7060","authenticated-orcid":false,"given":"Mandy","family":"Malick","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Sherbrooke"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3211-7364","authenticated-orcid":false,"given":"Nadine","family":"Sauv\u00e9","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Sherbrooke"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,9,14]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.3390\/diagnostics14111185"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.4103\/njcp.njcp_484_24"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(19)40063-9"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/21501351241311280"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2018.09.025"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezab006"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1136\/heartjnl-2019-315157"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2023.09.038"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocmr.2025.101899"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2016.05.048"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2009.11.013"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2010.03.047"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.hlc.2019.07.016"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.2006.00816.x"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1161\/JAHA.122.026862"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezad426"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1001\/jamacardio.2018.2747"},{"key":"e_1_3_3_19_2","doi-asserted-by":"publisher","DOI":"10.1136\/heartjnl-2020-318685"},{"key":"e_1_3_3_20_2","doi-asserted-by":"publisher","DOI":"10.1177\/1753495X19825964"},{"key":"e_1_3_3_21_2","first-page":"1062","article-title":"Pregnancy in women with complex congenital heart disease.
