Left ventricular pseudoaneurysm is a rare lesion that occurs when a contained free‐wall rupture occurs after a transmural myocardial infarction. Such a pseudoaneurysm may be lethal if subsequent rupture or progressive heart failure occurs. We describe a 67‐year‐old man who, one year after undergoing coronary artery bypass grafting, developed an infero‐apical left ventricular pseudoaneurysm between the bases of two papillary muscles without incurring significant mitral regurgitation. This was a highly unusual presentation. We were able to repair the aneurysm and restore normal mitral geometry without causing regurgitation. (J Card Surg 2010;25:668‐670)
