Coronary artery aneurysm commonly occurs secondary to atherosclerosis,but aneurysm formation after stenting is a rare phenomenon specially after drug eluting stent implantation. Drug-eluting stents (DES) elute antiproliferative drugs, can inhibit neointimal growth and may delay healing after vascular injury, and DES implantation may be associated with a risk of coronary artery aneurysm formation. Coronary aneurysms have been reported from 3 days to up to 4 years after DES implantation procedures, with varying clinical presentations. Incidence of coronary artery aneurysms after DES implantation is low within the first 9 months, with a reported incidence of 0.2% to 2.3%, a rate similar to that reported after bare-metal stent (BMS) implantation (0.3% to 3.9%). In our case,the patient is a nondiabetic ,nonhypertensive 68 year old male who underwent coronary angioplasty in the RCA with everolimus eluting stent following acute coronary syndrome.After few weeks the patient came with exertional angina and coronary angiography revealed stent aneurysm formation with new disease proximal to the stent.
