Left atrial dissection is a rare entity, mostly occurring after mitral valve surgery, with only a few cases described after myocardial infarction. The authors report a case of a 60-year-old man who presented with an inferior myocardial infarction, complicated with pseudoaneurysm of basal segment of left ventricular inferior wall, which expanded through the mitral ring to left atria, causing left atrial free wall dissection. The left ventriculo-atrial communication through the pseudoaneurysm caused major para-mitral regurgitation and the development of acute heart failure. Good clinical outcome was achieved with stabilization of acute heart failure with high-dose diuretic therapy and delayed cardiac surgery with closure of left ventriculo-atrial communication.
