Very late coronary aneurysm formation with subsequent stent thrombosis secondary to drug-eluting stent

Drug-eluting stents have changed the practice in interventional cardiology. With the widespread use of these stents important safety concerns regarding stent thrombosis and formation of coronary artery aneurysm have been expressed. While the majority of attention was focused on stent thrombosis, the formation of coronary aneurysm was only described in anecdotal reports. We report on a patient who suffered from very late stent thrombosis in association with coronary artery aneurysm formation secondary to drug-eluting stent but not to bare-metal stent.
