A Case of Coronary Artery Aneurysm after Sirolimus-Eluting Stent Implantation

ABSTRACT

This report describes the case of a 26-year-old male diagnosed with angina on exertion. A diagnostic coronary angiography revealed significant luminal narrowing at the middle third of the left anterior descending artery and proximal circumflex artery. The patient underwent implantation of sirolimus-eluting stents. Eight months after implantation of the stents, a follow-up coronary angiography showed intrastent coronary artery aneurysms. We suggest that the implantation of the sirolimus-eluting stent caused late formation of a coronary artery aneurysm.
