A72-year-old woman complaining of
orthopnea was admitted with cardiogenic shock. Her systolic blood
pressure was only 66mmHg and electrocardiogram showed high lateral
myocardial infarction. Transthoracic echocardiogram showed severe
mitral regurgitation and disruption of the anterolateral papillary
muscle. After orotracheal intubation and intraaortic balloon
pumping (IABP), coronary angiogram was performed and an occlusion
of the entrance of circumflex artery (＃11) was diagnosed. Percutaneous
coronary intervention was done successfully and emergency mitral
valve replacement was performed using a St. Jude Medical prosthetic
valve preserving the posterior mitral valve leaflet and mitral
apparatus. Her postoperative recovery was entirely uneventful
and she was followed up as an outpatient. Acute anterolateral
papillary muscle rupture is a rare complication of acute myocardial
infarction (AMI), although left coronary artery disease is associated
with it and immediate recanalization is an important issue to
rescue the patient.
