[Embolism in a fragment of the mitral papillary muscle to the left main coronary artery. A rare complication of valve replacement].
A 64-year-old man, who underwent double valve replacement for mitral and aortic incompetence due to infective endocarditis, presented with a coronary embolism of a fragment of mitral papillary muscle in the immediate post-operative period. The diagnosis, suggested by the sudden development of acute myocardial insufficiency during ventricular filling, was confirmed by the absence of clinical or electrical improvement during circulatory assistance and by surgical exploration of the left coronary artery. Complete recovery after embolectomy emphasises the value of the association of circulatory assistance and immediate myocardial revascularisation.
