A case of coronary artery true aneurysm developed after stent implantation / 대한내과학회지

ABSTRACT

Coronary aneurysm is a rare disorder, defined as a abnormal dilatation that exceeds 1.5 times the diameter of the adjacent segment of artery. Percutaneous transluminal coronary angioplasty is often associated with a coronary aneurysm and mechanical injury of vessel wall during the procedure is suspected as the cause. The reported incidence of coronary aneurysms in Caucasians was 4.9%, but the incidence in Asian population was 0.25%. Morphologically, aneurysms can be divided into true versus pseudo aneurysms. These differentiation by intravascular (interventional) ultrasound is important to predict prognosis of the coronary aneurysm. We experienced a case of coronary artery true aneurysm, that developed after coronary balloon angioplasty and stent implantation. So we report the case.
