Circumferential spontaneous coronary artery dissection in an elderly man: a case report.

An 82-year-old man developed acute inferior myocardial infarction. Emergent coronary angiography demonstrated thrombotic occlusion in the right coronary artery. Intracoronary thrombolytic therapy was performed with successful recanalization. However, circumferential dissection with luminal stenosis was revealed at the point of thrombus formation. Repeat angiography 6 months later showed resolution of the dissection. This is the first description of circumferential spontaneous coronary artery dissection. In addition, the present patient is older than any previous patients.
