ECG demonstrated new-onset atrial fibrillation. Transthoracic echocardiogram showed global impairment in left ventricular systolic function with left ventricular ejection fraction of 20%. Cardiac MRI (CMRI) demonstrated generalised severe myocarditis. A SARS-CoV-2 PCR was positive for SARS-CoV-2 RNA. As such, we diagnosed our patient with COVID-19-associated myocarditis based on CMRI appearances and positive SARS-CoV-2 swab. This case highlights that COVID-19-associated myocarditis can present as new atrial fibrillation and heart failure without the classic COVID-19-associated symptoms.<\/jats:p>","DOI":"10.1136\/bcr-2021-244027","type":"journal-article","created":{"date-parts":[[2021,7,12]],"date-time":"2021-07-12T12:35:04Z","timestamp":1626093304000},"page":"e244027","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":18,"title":["COVID-19-associated myocarditis presenting as new-onset heart failure and atrial fibrillation"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9753-3916","authenticated-orcid":false,"given":"Sean","family":"Gaine","sequence":"first","affiliation":[{"name":"Cardiology, St James's Hospital, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Devitt","sequence":"additional","affiliation":[{"name":"Department of Medicine, Fiona Stanley Hospital, Murdoch, Western Australia, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6086-3279","authenticated-orcid":false,"given":"John Joseph","family":"Coughlan","sequence":"additional","affiliation":[{"name":"Cardiology, Tallaght University Hospital, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ian","family":"Pearson","sequence":"additional","affiliation":[{"name":"Cardiology, St James's Hospital, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,7,12]]},"reference":[{"key":"2025082708074555000_14.7.e244027.1","doi-asserted-by":"crossref","first-page":"802","DOI":"10.1001\/jamacardio.2020.0950","article-title":"Association of cardiac injury with mortality in hospitalized patients with COVID-19 in Wuhan, China","volume":"5","author":"Shi","year":"2020","journal-title":"JAMA Cardiol"},{"key":"2025082708074555000_14.7.e244027.2","doi-asserted-by":"crossref","unstructured":"Inciardi RM , Lupi L , Zaccone G .
