We present a case of PM rupture due to isolated PM infarction in a patient with unobstructed coronary arteries, which could be misdiagnosed as a vegetation or other mass given the absence of regional wall motion abnormalities (RWMAs) on transthoracic echocardiogram. Our case highlights that in patients with severe mitral regurgitation and associated mitral valve mass, the absence of RWMAs should not exclude ischemic PM rupture from differential diagnosis.<\/jats:p>","DOI":"10.1111\/echo.14881","type":"journal-article","created":{"date-parts":[[2020,10,4]],"date-time":"2020-10-04T14:29:57Z","timestamp":1601821797000},"page":"1855-1859","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Isolated papillary muscle rupture with nonobstructive coronary artery disease, minimal myocardial infarction, and normal wall motion"],"prefix":"10.1111","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1921-8117","authenticated-orcid":false,"given":"Eleni S.","family":"Nakou","sequence":"first","affiliation":[{"name":"Department of Cardiology King\u2019s College Hospital London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konstantinos C.","family":"Theodoropoulos","sequence":"additional","affiliation":[{"name":"Department of Cardiology King\u2019s College Hospital London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hizbullah","family":"Shaikh","sequence":"additional","affiliation":[{"name":"Department of Histopathology King\u2019s College Hospital London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George","family":"Amin\u2010Youssef","sequence":"additional","affiliation":[{"name":"Department of Cardiology King\u2019s College Hospital London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark J.","family":"Monaghan","sequence":"additional","affiliation":[{"name":"Department of Cardiology King\u2019s College Hospital London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandros","family":"Papachristidis","sequence":"additional","affiliation":[{"name":"Department of Cardiology King\u2019s College Hospital London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,10,4]]},"reference":[{"issue":"3","key":"e_1_2_6_2_1","first-page":"I85","article-title":"Value of regional wall motion abnormality in the emergency room diagnosis of acute myocardial infarction.
