Successful treatment in a case of acute myocardial infarction due to spontaneous coronary artery dissection

Summary Spontaneous coronary dissection is a rare cause of myocardial ischemia, myocardial infarction, and sudden death. In the present case, we performed stenting only of the severe stenotic lesion of the dissection with a short bare metal stent, and left the remaining long length of dissection vessel untreated. Six months after coronary stenting, follow-up angiography revealed complete healing of the coronary dissection and no significant in-stent restenosis. This case clearly demonstrates the usefulness of intravascular ultrasound (IVUS) imaging in the diagnosis of coronary dissection and IVUS imaging guides to the choice of the best stenting.
