He was successfully treated with emergency double valve replacement using mechanical valves. The pathogenesis of acute rupture of the anterior chordae tendinae, without any evidence of infective endocarditis or ischemic heart disease seems to have been attrition of the subvalvular mitral apparatus by the chronic regurgitant jet of aortic incompetence with chronic volume overload. We review the literature with specific focus on the occurrence of this unusual event.<\/jats:p>","DOI":"10.1186\/1749-8090-1-33","type":"journal-article","created":{"date-parts":[[2006,10,6]],"date-time":"2006-10-06T20:25:30Z","timestamp":1160166330000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Double valve replacement for acute spontaneous left chordal rupture secondary to chronic aortic incompetence"],"prefix":"10.1186","volume":"1","author":[{"given":"Sandeep","family":"Agarwala","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanjay","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Berridge","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jim","family":"McLenachan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David J","family":"O'Regan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2006,10,6]]},"reference":[{"issue":"5","key":"33_CR1","first-page":"512","volume":"2","author":"D Horstkotte","year":"1993","unstructured":"Horstkotte D, Schulte HD, Niehues R, Klein RM, Piper C, Strauer BE: Diagnostic and therapeutic considerations in acute, severe mitral regurgitation: experience in 42 consecutive patients entering the intensive care unit with pulmonary edema.
