  • Look Inside

A 56-year-old woman with a history of myocardial infarction was admitted to our hospital because of chest pain. Electrocardiogram showed ischemic ST - Tchanges, and stress T1 myocardial scintigraphy showed persistent defect in the posterolateral wall and redistri-bution in the inferior wall. The coronary angiogram revealed total obstruction at # 11 of the left circumflex artery and 90%stenosis at # 3 of the right coronary artery (RCA). PTCA for RCA # 3 was undertaken and the stenosis was dilated without coronary dissection. Three months later, the coronary angiogram showed aneurysm formation with a size of 8×3 mm and with 65 % stenosis at the same portion. Six months later, the coronary aneurysm was markedly reduced, but reste-nosis had progressed to 75%. Therefore. we performed GE II stent implantation for RCA # 3 and the lesion was dilated adequately and 3 months later, restenosis had disappeared. Thus, we had encountered a rare case in whichl we could observe the natural course of a coro-nary aneurysm following PTCA.
