Acute myocardial infarction in an 80 year-old woman caused by left main occlusion with concomitant chronic total occlusions of right and left coronary artery: successful treatment with percutaneous revascularization.
Although acute left main coronary artery occlusion is rare, it carries a very high mortality rate. Following the encouraging results of trials testing the effect of primary percutaneous coronary intervention, more cases of left main stenosis are treated as culprit lesion in acute myocardial infarction. Few cases of primary percutaneous intervention on left main occlusion have been published. We present the case of an elderly patient presenting with acute myocardial infarction complicated by cardiogenic shock due to left main occlusion, with concomitant chronic total occlusion of right and left anterior descending coronary arteries. Successful percutaneous intervention as a bridge to coronary artery bypass grafting was performed with stent implantation, which resulted in the relief of obstruction, the restoration of blood flow and the immediate clinical improvement of the patient. The patient left the hospital in good condition after 11 days, although she had refused the proposed coronary artery bypass grafting.
