Mitral regurgitation after myocardial infarction. Coronary artery bypass grafting and mitral valve replacement with chordae preservation.
A patient with acute ischemic mitral regurgitation after acute myocardial infarction required emergency coronary artery bypass grafting and mitral valve replacement with chordae preservation. For severe mitral regurgitation and heart failure due to myocardial infarction and ischemic papillary muscle dysfunction, mitral valve replacement with chordae preservation was effective. Here, we discuss the etiology of ischemic mitral regurgitation and the operative method for valve repair or replacement.
