Left ventricular pseudoaneurysm is a rare mechanical complication of acute myocardial infarction. In the present case, an 80-year-old man presenting with a subacute non-ST segment elevation myocardial infarction was found to have an occluded second obtuse marginal branch of the left circumflex coronary artery. Following the implantation of two drug-eluting stents, the patient developed no-reflow phenomenon. Coronary angiography 6 weeks later revealed persistence of the no-reflow phenomenon. During the left ventriculogram, a massive pseudoaneurysm was diagnosed and the patient successfully underwent emergency surgery. The persistence of no-reflow was likely due to the fact that the myocardial territory supplied by the infarct-related artery was completely necrosed resulting in persistent flow impairment through the vessel.
