In the latter case, diagnosis can be challenging to confirm through transthoracic echocardiography alone, and may require a cardiac computed tomography angiography examination for a definitive diagnosis. For patients experiencing recurrent large volumes of bloody pericardial effusion within one month, and exhibiting no atrial enlargement but showing abnormalities of the atrial wall in echocardiography, it is important to be vigilant about the potential for atrial aneurysm rupture in the heart. Timely treatment is essential to prevent the progression of the condition, which could otherwise result in a poor prognosis.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fped.2024.1369345","type":"journal-article","created":{"date-parts":[[2024,4,2]],"date-time":"2024-04-02T05:13:39Z","timestamp":1712034819000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Case report of a ruptured right atrial aneurysm in a child and a comprehensive literature review"],"prefix":"10.3389","volume":"12","author":[{"given":"Jie","family":"Zhou","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Xin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiao","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mei","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,4,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"639","DOI":"10.1111\/j.0742-2822.2004.03156.x","article-title":"Right atrial aneurysm in adults\u2013report of three cases and review of literature","volume":"21","author":"Chockalingam","year":"2004","journal-title":"Echocardiography"},{"key":"B2","doi-asserted-by":"publisher","first-page":"104","DOI":"10.21470\/1678-9741-2018-0047","article-title":"Congenital aneurysm of the right atrium: two cases report","volume":"34","author":"Melo","year":"2019","journal-title":"Braz J Cardiovasc Surg"},{"key":"B3","doi-asserted-by":"publisher","first-page":"124","DOI":"10.1161\/01.CIR.38.1.124","article-title":"Congenital aneurysm (diverticulum) of the right atrium.
