[A case of acute postinfarction mitral regurgitation and cardiogenic shock caused by a total rupture of the papillary muscle].
We report a case of mitral regurgitation caused by a total rupture of the posterior papillary muscle that had occurred after acute myocardial infarction. A 72-year-old woman was transferred to our hospital for cardiogenic shock. Echocardiogram revealed massive mitral regurgitation and prolapse of posterior mitral leaflet presumably due to a rupture of a papillary muscle. Cardiac catheterization demonstrated a total occlusion in the segment 2 of the right coronary artery. She had developed progressively increasing heart failure even though the patient had received a successful PTCA for a total occlusion of the right coronary artery. She underwent an emergency mitral valve replacement with preservation of the posterior leaflet using a SJM prosthetic valve. Intraoperative findings were confirmative of total rupture of the posterior papillary muscle. A postoperative course was uneventful. This case is the seventh case which has been reported as the successful operation of a total rupture of the papillary muscle in Japan.
