Both transthoracic and transesophageal echocardiography demonstrated a posteriorly directed eccentric jet of severe mitral regurgitation with flail anterior mitral valve leaflet attached presumably to the anterior papillary muscle. Intraoperative findings demonstrated rupture of the postero-medial papillary muscle attached via chords to the anterior mitral valve leaflet. This case serves to remind us that both the anterior and posterior leaflets of the mitral valve are attached to both papillary muscle heads. The direction and eccentricity of the mitral regurgitant jet on echocardiography helps to locate the leaflet involved, but not necessarily the coexisting papillary muscle pathology.<\/jats:p>","DOI":"10.1186\/1476-7120-6-5","type":"journal-article","created":{"date-parts":[[2008,1,19]],"date-time":"2008-01-19T07:13:25Z","timestamp":1200726805000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Acute severe mitral regurgitation: consideration of papillary muscle architecture"],"prefix":"10.1186","volume":"6","author":[{"given":"Andrew","family":"Czarnecki","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amar","family":"Thakrar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tielan","family":"Fang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Lytwyn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roien","family":"Ahmadie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edward","family":"Pascoe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Davinder S","family":"Jassal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2008,1,18]]},"reference":[{"key":"187_CR1","doi-asserted-by":"publisher","first-page":"272","DOI":"10.1016\/0735-1097(91)90738-U","volume":"17","author":"RB Himmelman","year":"1991","unstructured":"Himmelman RB, Kusumoto F, Oken K, Lee E, Cahalan MK, Shah PM, Schiller MB: The flail mitral valve: echocardiographic findings by precordial and trans-esophageal imaging and Doppler color flow mapping.
