Here, we describe a case of papillary muscle rupture caused by a microscopic MI. A 76-year-old woman was referred to our institution, where she developed cardiac arrest upon admission. Severe mitral regurgitation was noted without significant coronary artery lesions. Emergency surgery was performed, and posteromedial papillary muscle rupture was observed. Postoperatively, cardiac magnetic resonance imaging revealed a microscopic MI of the posteromedial papillary muscle.<\/jats:p>","DOI":"10.1093\/icvts\/ivz201","type":"journal-article","created":{"date-parts":[[2019,7,24]],"date-time":"2019-07-24T07:22:13Z","timestamp":1563952933000},"page":"971-972","source":"Crossref","is-referenced-by-count":1,"title":["Ischaemic papillary muscle rupture without significant coronary artery lesion"],"prefix":"10.1093","volume":"29","author":[{"given":"Yuichiro","family":"Kitada","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Nerima Hikarigaoka Hospital, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mamoru","family":"Arakawa","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Nerima Hikarigaoka Hospital, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atsushi","family":"Miyagawa","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Nerima Hikarigaoka Hospital, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8806-5110","authenticated-orcid":false,"given":"Homare","family":"Okamura","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Nerima Hikarigaoka Hospital, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2019,8,5]]},"reference":[{"key":"2019112510403384400_ivz201-B1","doi-asserted-by":"crossref","first-page":"424","DOI":"10.1016\/S0002-9149(99)80119-2","article-title":"Left ventricular and papillary muscle rupture following blunt chest trauma","volume":"76","author":"Cho","year":"1995","journal-title":"Am J Cardiol"},{"key":"2019112510403384400_ivz201-B2","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1186\/1749-8090-3-61","article-title":"Cardiogenic shock as a complication of acute mitral valve regurgitation following posteromedial papillary muscle infarction in the absence of coronary artery disease","volume":"3","author":"Bizzarri","year":"2008","journal-title":"J Cardiothorac Surg"},{"key":"2019112510403384400_ivz201-B3","doi-asserted-by":"crossref","first-page":"538","DOI":"10.1253\/circj.CJ-09-0648","article-title":"Long-term clinical course of patients with isolated myocardial bridge","volume":"74","author":"Kim","year":"2010","journal-title":"Circ J"},{"key":"2019112510403384400_ivz201-B4","doi-asserted-by":"crossref","first-page":"108","DOI":"10.15420\/icr.2018.15.2","article-title":"Primary microvascular angina: clinical characteristics, pathogenesis and management","volume":"13","author":"Lanza","year":"2018","journal-title":"Interv Cardiol"},{"key":"2019112510403384400_ivz201-B5","doi-asserted-by":"crossref","first-page":"661","DOI":"10.1016\/j.jcmg.2010.03.006","article-title":"Diagnostic value of CMR in patients with biomarker-positive acute chest pain and unobstructed coronary arteries","volume":"3","author":"Mather","year":"2010","journal-title":"JACC Cardiovasc Imaging"}],"container-title":["Interactive CardioVascular and Thoracic Surgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/icvts\/article-pdf\/29\/6\/971\/31117728\/ivz201.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/icvts\/article-pdf\/29\/6\/971\/31117728\/ivz201.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,11,25]],"date-time":"2019-11-25T10:41:59Z","timestamp":1574678519000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/icvts\/article\/29\/6\/971\/5543878"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,8,5]]},"references-count":5,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2019,8,5]]},"published-print":{"date-parts":[[2019,12,1]]}},"URL":"https:\/\/doi.org\/10.1093\/icvts\/ivz201","relation":{},"ISSN":["1569-9285"],"issn-type":[{"type":"electronic","value":"1569-9285"}],"subject":[],"published-other":{"date-parts":[[2019,12]]},"published":{"date-parts":[[2019,8,5]]}}}
