Coronary pseudoaneurysms following implantation of drug-eluting stents, although rare, are not unknown. Nearly all such cases have been reported in patients with sirolimus or paclitaxel polymer-based stents. We describe a case of coronary pseudoaneurysm developing with a non-polymer-based drug-eluting stent in a 50-year-old man who was successfully managed by coronary artery bypass grafting.
