A late coronary aneurysm after sirolimus stent implantation which was treated with coronary graft stent

Drug eluting stents are being used frequently because of their less restenotic properties. However, their effect on preventing neo-intimal hyperplasia may cause many adverse effects such as coronary artery aneurysm (CAA). We report a case that presented with a CAA which was the latest developed CAA after the implantation of drug eluting stents in literature so far. A 57-year-old male presented with dyspnea and typical angina on effort. Coronary angiography was performed. A large CAA was detected at the site of a drug eluting stent which was implanted in the LAD artery 5.5 years ago. It was treated with a coronary stent graft successfully.
