The underlying mechanisms of this thrombus in the COVID-19 infection may be attributed to the hypercoagulation and inflammatory state of the disease incurred by the SARS-CoV-2 virus.<\/jats:p>","DOI":"10.3389\/fped.2021.656720","type":"journal-article","created":{"date-parts":[[2021,6,25]],"date-time":"2021-06-25T04:26:26Z","timestamp":1624595186000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Case Report: Acute Intracardiac Thrombosis in Children With Coronavirus Disease 2019 (COVID-19)"],"prefix":"10.3389","volume":"9","author":[{"given":"Hamid","family":"Bigdelian","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohsen","family":"Sedighi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad Reza","family":"Sabri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bahar","family":"Dehghan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chehreh","family":"Mahdavi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alireza","family":"Ahmadi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mehdi","family":"Ghaderian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hamid","family":"Rahimi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atefeh","family":"Sadeghizadeh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Monirsadat","family":"Emadoleslami","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seyed Nasser","family":"Mostafavi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rana","family":"Saleh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Niloofar","family":"Javadi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maryam","family":"Derakhshan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zahra","family":"Pourmoghaddas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shima","family":"Sarfarazi Moghadam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2021,6,25]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"811","DOI":"10.1001\/jamacardio.2020.1017","article-title":"Cardiovascular implications of fatal outcomes of patients with coronavirus disease 2019 (COVID-19)","volume":"5","author":"Guo","year":"2020","journal-title":"JAMA Cardiol."},{"key":"B2","unstructured":"Covid-192021"},{"key":"B3","doi-asserted-by":"publisher","first-page":"2649","DOI":"10.2147\/IDR.S259064","article-title":"The coronavirus disease 2019 (COVID-19) in children: a study in an Iranian children's referral hospital","volume":"13","author":"Mahmoudi","year":"2020","journal-title":"Infect Drug Resist."},{"key":"B4","doi-asserted-by":"publisher","first-page":"311","DOI":"10.1007\/s40256-020-00420-2","article-title":"COVID 19 pandemic: cardiovascular complications and future implications","volume":"20","author":"Bandyopadhyay","year":"2020","journal-title":"Am J Cardiovasc Drugs."},{"key":"B5","doi-asserted-by":"publisher","first-page":"1094","DOI":"10.1111\/jth.14817","article-title":"Anticoagulant treatment is associated with decreased mortality in severe coronavirus disease 2019 patients with coagulopathy","volume":"18","author":"Tang","year":"2020","journal-title":"J Thromb Haemost"},{"key":"B6","doi-asserted-by":"publisher","first-page":"1738","DOI":"10.1111\/jth.14850","article-title":"Hypercoagulability of COVID-19 patients in intensive care unit.
